SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Heap leaching is an industrial mining process to extract precious metals, copper, uranium, and other compounds from ore via a series of chemical reactions that absorb specific minerals and then re-separates them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ore, whereas in situ mining lacks these liners and pulls pregnant solution up to obtain the minerals. Most mining companies, favor the economic feasibility of the heap leaching, considering that heap leaching is a better alternative to conventional processing (such as flotation, agitation, and vat leaching). Additionally, dump leaching is an essential part of most copper mining operations and along with other deterministic factors, determines the quality grade of the produced material. Due to the effect that the dump leaching has, i.e. it can contribute substantially to the economic viability of the mining process it is advantageous to include the results of the leaching operation in the economic overall project evaluation. This, in effect, requires that the key controllable variables, which have an effect on the recovery of the metal and the quality of solution coming from a dump leaching process. The process has ancient origins; one of the classical methods for the manufacture of copperas (iron sulfate) was to heap up iron pyrite and collect the leachate from the heap, which was then boiled with iron to produce iron(II) sulfate

Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Asteroid mining is the exploitation of raw materials from asteroids and other minor planets, including near-Earth objects. Minerals and volatiles could be mined from an asteroid or spent comet then used in space for in-situ utilization (e.g. construction materials and rocket propellant) or taken back to Earth. These include gold, iridium, silver, osmium, palladium, platinum, rhenium, rhodium, ruthenium and tungsten for transport back to Earth; iron, cobalt, manganese, molybdenum, nickel, aluminium, and titanium for construction; water and oxygen to sustain astronauts; as well as hydrogen, ammonia, and oxygen for use as rocket propellant. Due to the astronomically high costs of current space transportation, extraction techniques still being developed and lingering uncertainties about target selection, terrestrial mining is currently the only means of raw mineral acquisition today. Based on known terrestrial reserves, and growing consumption in both developed and developing countries, key elements needed for modern industry and food production could be exhausted on Earth within 50–60 years. These include phosphorus, antimony, zinc, tin, lead, indium, silver, gold and copper. In response, it has been suggested that platinum, cobalt and other valuable elements from asteroids may be mined and sent to Earth for profit, used to build solar-power satellites and space habitats, and water processed from ice to refuel orbiting propellant depots. Although asteroids and Earth accreted from the same starting materials, Earth's relatively stronger gravity pulled all heavy siderophilic (iron-loving) elements into its core during its molten youth more than four billion years ago. This left the crust depleted of such valuable elements until a rain of asteroid impacts re-infused the depleted crust with metals like gold, cobalt, iron, manganese, molybdenum, nickel, osmium, palladium, platinum, rhenium, rhodium, ruthenium and tungsten (some flow from core to surface does occur, e.g. at the Bushveld Igneous Complex, a famously rich source of platinum-group metals). Today, these metals are mined from Earth's crust, and they are essential for economic and technological progress. Hence, the geologic history of Earth may very well set the stage for a future of asteroid mining. In 2006, the Keck Observatory announced that the binary Jupiter trojan 617 Patroclus, and possibly large numbers of other Jupiter trojans, are likely extinct comets and consist largely of water ice. Similarly, Jupiter-family comets, and possibly near-Earth asteroids that are extinct comets, might also provide water. The process of in-situ resource utilization—using materials native to space for propellant, thermal management, tankage, radiation shielding, and other high-mass components of space infrastructure—could lead to radical reductions in its cost. Although whether these cost reductions could be achieved, and if achieved would offset the enormous infrastructure investment required, is unknown. Ice would satisfy one of two necessary conditions to enable "human expansion into the Solar System" (the ultimate goal for human space flight proposed by the 2009 "Augustine Commission" Review of United States Human Space Flight Plans Committee): physical sustainability and economic sustainability. From the astrobiological perspective, asteroid prospecting could provide scientific data for the search for extraterrestrial intelligence (SETI). Some astrophysicists have suggested that if advanced extraterrestrial civilizations employed asteroid mining long ago, the hallmarks of these activities might be detectable. Why extraterrestrials would have resorted to asteroid mining in near proximity to earth, with its readily available resources, has not been explained.

Site Characterization and In Situ Bioremediation Case History
 
01:54
Penn E&R’s In Situ Remediation Group is currently applying advanced delivery technology for an in situ bioremediation project to remediate soil and ground water at a former industrial operation in eastern Pennsylvania. Significant concentrations of chlorinated volatile organic compounds (CVOCs) including trichloroethene (TCE) are being reduced on an accelerated basis by this process. This process will reduce long term costs associated with managing this property so that it will comply with Pennsylvania’s Brownfields Program (Act 2) standards.

Yellow Cradle to Grave (Uranium Mining Fallout)

The nuclear industry is a many-headed toxic beast – nuclear power and nuclear weapons are just the most visible ones. Mining, milling, processing, reprocessing, manufacturing, and transporting nuclear materials are some other heads of the beast that are less visible. All are desecrating Mother Earth and killing her peoples. It’s time to deal with the initial stage of this problem. We can begin by cleaning up the abandoned uranium mines and placing a National Environmental Security Moratorium on all uranium extraction. https://www.popularresistance.org/the-toxic-threat-of-abandoned-uranium-mines-in-the-united-states/ USA Cows Fed Copper To Hide Radiated Gray Spots ☠ Lake By Uranium Mine Melts Steel! surprise pop up bonus link Coldplay - Yellow https://youtu.be/yKNxeF4KMsY USA Cows Fed Copper To Hide Radiated Gray Spots ☠ Lake By Uranium Mine Melts Steel! https://youtu.be/d1lMSpP9WYQ Irresponsible corporations and negligent government agencies have abandoned more than 10,000 toxic uranium mines throughout the US. These hazardous mines poison our air, land and water and harm public health. Currently no laws require cleanup of these dangerous sites. A new campaign, Clean Up The Mines!, aims for remediation of these mines through federal legislation and action, and public education. Abandoned Uranium Mines (AUMs) The Environmental Protection Agency and US Geological Survey document over 10,000 abandoned uranium mines in the US, most in 15 western states on public, private, and tribal lands. Over 4,200 of these mines produced uranium that was sold to the US Atomic Energy Commission for use in nuclear weapons from the 1940s through the 1970s. Starting in the 1960s, much of the mining was done to provide fuel for nuclear power plants. There are several AUMs in and near the Grand Canyon, 169 of them within 40 miles of Mt. Rushmore, and eight right on the edge of Grand Teton / Yellowstone National Parks. One in seven (10 million) people in the western US lives within 50 miles of an AUM. CLICK HERE TO SIGN THE PETITION TO CLEAN UP THE MINES AND ALL Future Uranium Mining Down! http://www.cleanupthemines.org/action/ AUM hazards and contamination pathways. Physical hazards of AUMs come from unmarked, unprotected mine entrances, cliffs, falling rocks, and collapsing buildings and equipment. Wind picks up radioactive dust from rock piles and blows it for miles people breathe fine particles into their lungs, resulting in much higher levels of lung cancer near AUMs. People carry the radioactive dust, dirt, and mud around on their clothes and shoes, spreading the contamination to their homes and families. One of the decay elements of uranium is radon gas. It seeps up through the ground in many areas around mine sites where people and animals breathe it in. Exposure to radon gas is the second leading cause of lung cancer in the US. Water picks up radiation in a variety of ways – rain washes radioactive dust from the air and rocks and carries it into streams and rivers. Surface and underground water dissolve uranium from rock and dust. This is particularly true of uranium that has been exposed to oxygen, which changes it from UIV to UVI, which is more soluble in water. (This is the principle used in ‘In Situ Leaching’, similar to fracking techniques, the method most commonly used now.) The result is polluted rivers, lakes, and aquifers, with no safe available drinking water for thousands of communities.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Dump leaching is an industrial process to extract precious metals and copper from ores. Dump leaching is similar to heap leaching, however in the case of dump leaching ore is taken directly from the mine and stacked on the leach pad without crushing where, in the case of gold and silver, the dump is irrigated with a dilute cyanide solution that percolates through the ore to dissolve gold and silver. The solution containing gold and silver exits the base of the dump, is collected and precious metals extracted. The resultant barren solution is recharged with additional cyanide and returned to the dump. This method of leaching is usually suitable for low grade ores because it is very low cost. However, it operates with slow kinetics and may take up about 1 to 2 years to extract 50% of the desired mineral.

Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Bioremediation is a waste management technique that involves the use of organisms to remove or neutralize pollutants from a contaminated site. According to the United States EPA, bioremediation is a “treatment that uses naturally occurring organisms to break down hazardous substances into less toxic or non toxic substances”. Technologies can be generally classified as in situ or ex situ. In situ bioremediation involves treating the contaminated material at the site, while ex situ involves the removal of the contaminated material to be treated elsewhere. Some examples of bioremediation related technologies are phytoremediation, bioventing, bioleaching, landfarming, bioreactor, composting, bioaugmentation, rhizofiltration, and biostimulation. Bioremediation may occur on its own (natural attenuation or intrinsic bioremediation) or may only effectively occur through the addition of fertilizers, oxygen, etc.,that help in enhancing the growth of the pollution-eating microbes within the medium (biostimulation). For example, the US Army Corps of Engineers demonstrated that windrowing and aeration of petroleum-contaminated soils enhanced bioremediation using the technique of landfarming. Depleted soil nitrogen status may encourage biodegradation of some nitrogenous organic chemicals, and soil materials with a high capacity to adsorb pollutants may slow down biodegradation owing to limited bioavailability of the chemicals to microbes. Recent advancements have also proven successful via the addition of matched microbe strains to the medium to enhance the resident microbe population's ability to break down contaminants. Microorganisms used to perform the function of bioremediation are known as bioremediators. However, not all contaminants are easily treated by bioremediation using microorganisms. For example, heavy metals such as cadmium and lead are not readily absorbed or captured by microorganisms. A recent experiment, however, suggests that fish bones have some success absorbing lead from contaminated soil. Bone char has been shown to bioremediate small amounts of cadmium, copper, and zinc. A recent experiment, suggests that the removals of pollutants (nitrate, silicate, chromium and sulphide) from tannery wastewater were studied in batch experiments using marine microalgae. The assimilation of metals such as mercury into the food chain may worsen matters. Phytoremediation is useful in these circumstances because natural plants or transgenic plants are able to bioaccumulate these toxins in their above-ground parts, which are then harvested for removal. The heavy metals in the harvested biomass may be further concentrated by incineration or even recycled for industrial use. Some damaged artifacts at museums contain microbes which could be specified as bio remediating agents. In contrast to this situation, other contaminants, such as aromatic hydrocarbons as are common in petroleum, are relatively simple targets for microbial degradation, and some soils may even have some capacity to autoremediate, as it were, owing to the presence of autochthonous microbial communities capable of degrading these compounds. The elimination of a wide range of pollutants and wastes from the environment requires increasing our understanding of the relative importance of different pathways and regulatory networks to carbon flux in particular environments and for particular compounds, and they will certainly accelerate the development of bioremediation technologies and biotransformation processes.

Overview of In- and Ex-Situ Technologies in Development for the Treatment of PFAS
 
01:21:39
Presented by Erika Houtz, PhD, PFAS Analytical Lead at Arcadis and Jeffrey McDonough, M.S., P.E. Principal Environmental Engineer at Arcadis Per- and polyfluoroalkyl substances (PFASs) comprise a diverse class of contaminants, which include PFOS (perfluorooctane sulfonate) and PFOA (perfluorooctanoic acid). PFASs are not amenable to bioremediation or conventional chemical treatment, and this limits in situ remediation options. PFAS are relatively ubiquitous in the environment at low concentrations, but source areas exhibit higher PFAS concentrations. While the USEPA Health Advisory Limit of 70 nanograms per liter for the summation of PFOA and PFOS is not a maximum contaminant level (MCL), to be protective of potential beneficial reuse aquifers, PFAS groundwater plumes emanating from source zones will require some form of active management. The use of conventional sorbents, such as granular activated carbon (GAC) and anion exchange (AIX) resins, to address PFASs in water have become a “de facto” interim measure in response to immediate needs for PFAS removal from drinking water. Challenges of more comprehensive PFAS treatment in drinking water may also be addressed using technologies such as reverse osmosis or nano-filtration. Extending these technologies to extracted groundwater for remediation purposes, which have various degrees of geochemical and co-contaminant competition, often requires a treatment train, combining conventional sorbents and engineered filtration with more innovative and emerging remediation solutions for PFASs. These emerging solutions include many types of technologies to address source zones, mitigate mass flux in aquifers, or address PFASs in extracted water to improve the efficiency of conventional drinking water treatment technologies. There are new flocculation technologies, novel AIX resins, new engineered sorptive media, electrochemical oxidation, electrocoagulation, sonolysis, and advanced oxidation processes combined with advanced reductive processes. Remediation technologies for PFAS source zones in soil are primarily limited to excavation with onsite or offsite incineration and in situ soil stabilization. For in situ soil stabilization to be considered viable, ongoing research and development is being conducted to evaluate the longevity of fixation amidst circumneutral pH and biotransformation, which may enhance PFAS dissolution. Remediation of PFAS source zones and the associated groundwater plumes presently requires multiple technologies to protect human health in a cost-conscious manner. An investment in research and development to explore new technologies is part of a key initiative for groundwater preservation and protection of human health. The technologies discussed here will be presented, and their applicability/readiness to the remediation market will be assessed.

What is REVEGETATION? What does REVEGETATION mean? REVEGETATION meaning - REVEGETATION pronunciation - REVEGETATION definition - REVEGETATION explanation - How to pronounce REVEGETATION? Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Revegetation is the process of replanting and rebuilding the soil of disturbed land. This may be a natural process produced by plant colonization and succession, manmade rewilding projects, accelerated process designed to repair damage to a landscape due to wildfire, mining, flood, or other cause. Originally the process was simply one of applying seed and fertilizer to disturbed lands, usually grasses or clover. The fibrous root network of grasses is useful for short-term erosion control, particularly on sloping ground. Establishing long-term plant communities requires forethought as to appropriate species for the climate, size of stock required, and impact of replanted vegetation on local fauna. The motivations behind revegetation are diverse, answering needs that are both technical and aesthetic, but it is usually erosion prevention that is the primary reason. Revegetation helps prevent soil erosion, enhances the ability of the soil to absorb more water in significant rain events, and in conjunction reduces turbidity dramatically in adjoining bodies of water. Revegetation also aids protection of engineered grades and other earthworks. Revegetation is often used to join up patches of natural habitat that have been lost, and can be a very important tool in places where much of the natural vegetation has been cleared. It is therefore particularly important in urban environments, and research in Brisbane has shown that revegetation projects can significantly improve urban bird populations The Brisbane study showed that connecting a revegetation patch with existing habitat improved bird species richness, while simply concentrating on making large patches of habitat was the best way to increase bird abundance. Revegetation plans therefore need to consider how the revegetated sites are connected with existing habitat patches. Revegetation in agricultural areas can support breeding bird populations, but often it supports more common species, rather than those that are in decline. Mine reclamation may involve soil amendment, replacement, or creation, particularly for areas that have been strip mined or suffered severe erosion or soil compaction. In some cases, the native soil may be removed prior to construction and replaced with fill for the duration of the work. After construction is completed, the fill is again removed and replaced with the reserved native soil for revegetation. Mycorrhizae, symbiotic fungal-plant communities, are important to the success of revegetation efforts. Most woody plant species need these root-fungi communities to thrive, and nursery or greenhouse transplants may not have sufficient or correct mycorrhizae for good survival. Regional differences in ectomycorrhizal fungi may also affect the success of revegetation.

What is OIL SHALE INDUSTRY? What does OIL SHALE INDUSTRY mean? OIL SHALE INDUSTRY meaning - OIL SHALE INDUSTRY definition - OIL SHALE INDUSTRY explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Oil shale industry is an industry of mining and processing of oil shale—a fine-grained sedimentary rock, containing significant amounts of kerogen (a solid mixture of organic chemical compounds), from which liquid hydrocarbons can be manufactured. The industry has developed in Brazil, China, Estonia and to some extent in Germany and Russia. Several other countries are currently conducting research on their oil shale reserves and production methods to improve efficiency and recovery. However, Australia has halted their pilot projects due to environmental concerns. Estonia accounted for about 70% of the world's oil shale production in a study published in 2005. Oil shale has been used for industrial purposes since the early 17th century, when it was mined for its minerals. Since the late 19th century, shale oil has also been used for its oil content and as a low grade fuel for power generation. However, barring countries having significant oil shale deposits, its use for power generation is not particularly widespread. Similarly, oil shale is a source for production of synthetic crude oil and it is seen as a solution towards increasing domestic production of oil in countries that are reliant on imports. Oil shale is mined either by traditional underground mining or surface mining techniques. There are several mining methods available, but the common aim of all these methods is to fragment the oil shale deposits in order to enable the transport of shale fragments to a power plant or retorting facility. The main methods of surface mining are open pit mining and strip mining. An important method of sub-surface mining is the room-and-pillar method. In this method, the material is extracted across a horizontal plane while leaving "pillars" of untouched material to support the roof. These pillars reduce the likelihood of a collapse. Oil shale can also be obtained as a by-product of coal mining. The largest oil shale mine in the world is the Estonia Mine, operated by Enefit Kaevandused. In 2005, Estonia mined 14.8 million tonnes of oil shale. During the same period, mining permits were issued for almost 24 million tonnes, with applications being received for mining an additional 26 million tonnes. In 2008, the Estonian Parliament approved the "National Development Plan for the Use of Oil Shale 2008-2015", which limits the annual extraction of oil shale to 20 million tonnes. Oil shale can be used as a fuel in thermal power plants, wherein oil shale is burnt like coal to drive the steam turbines. As of 2012, there are oil shale-fired power plants in Estonia with a generating capacity of 2,967 megawatts (MW), China, and Germany. Also Israel, Romania and Russia have run oil shale-fired power plants, but have shut them down or switched to other fuels like natural gas. Jordan and Egypt have announced their plans to construct oil shale-fired power plants, while Canada and Turkey plan to burn oil shale at the power plants along with coal. Thermal power plants which use oil shale as a fuel mostly employ two types of combustion methods. The traditional method is Pulverized combustion (PC) which is used in the older units of oil shale-fired power plants in Estonia, while the more advanced method is Fluidized bed combustion (FBC), which is used in the Holcim cement factory in Dotternhausen, Germany, and was used in the Mishor Rotem power plant in Israel. The main FBC technologies are Bubbling fluidized bed combustion (BFBC) and Circulating fluidized bed combustion (CFBC).

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Aquatic biomonitoring is the science of inferring the ecological condition of rivers, lakes, streams, and wetlands by examining the organisms that live there. While aquatic biomonitoring is the most common form of such biomonitoring, any ecosystem can be studied in this manner. Biomonitoring typically takes different approaches: Bioassays, where test organisms are exposed to an environment to see if mutations or deaths occur. Typical organisms used in bioassays are fish, water fleas (Daphnia), and frogs. Community assessments, also called biosurveys, where an entire community of organisms is sampled, to see what types of taxa remain. In aquatic ecosystems, these assessments often focus on invertebrates, algae, macrophytes (aquatic plants), fish, or amphibians. Rarely, other large vertebrates (reptiles, birds, and mammals) are considered as well. Online biomonitoring devices, using the ability of animals to permanently taste their environment. Different types of animals are used for that purpose either under lab or field conditions. The use of valve opening/closing activity of clams is one of the possible ways to monitor in-situ the quality of freshwater and coastal waters. Aquatic invertebrates have the longest history of use in biomonitoring programs. In typical unpolluted temperate streams of Europe and North America, certain insect taxa predominate. Mayflies (Ephemeroptera), caddisflies (Trichoptera), and stoneflies (Plecoptera) are the most common insects in these undisturbed streams. In rivers disturbed by urbanization, agriculture, forestry, and other perturbations, flies (Diptera), and especially midges (family Chironomidae) predominate. Aquatic invertebrates are responsive to climate change. Aquatic Biomonitoring is important in monitoring marine life and their ecosystems. Monitoring aquatic life can also be beneficial in understanding land ecosystems as well. Before there were tetrapods, there were fish. These fish then evolved into tetrapods that we see today. Because of this, aquatic life still has a major impact on life on land. Aquatic biomonitoring can represent the overall health and status of the environment, detect different environmental trends and how different stressors will affect those trends, and interpret the affect of different environmental activity will have on the overall health of the environment. Pollution and general stresses to aquatic life can have a huge impact on the environment in general. The main sources of pollution to oceans, rivers, and lakes are sewage, oil spills, land runoff, littering, ocean mining, and nuclear waste. These types of pollution cause a huge upset to marine life and can endanger any species in the water or that live close to the water. When aquatic species are affected, it causes a ripple effect. Many aquatic animals are a main food source for many land animals. For example: if a specific species of fish ingest toxins and become sick, the birds that ingest that species of fish will also become sick. Then the animal that ingest that bird will also become sick. This is a problem that can be avoided by monitoring all life and conditions in different bodies of water, including fresh and salt water. The main draw back on aquatic biomonitoring is simplifying data and making data easier for all to understand. Taking data from monitoring sites and making it available for people to use in the health fields and other environmental fields can be a challenge. Mechanisms that are used for Aquatic Biomonitoring are monitoring and assessing aquatic species and ecosystems, monitoring the behavior of certain aquatic species and assessing any changes in species behavior, and looking at contaminants in the water and their effect on marine life. Water is graded on several scales. One is the water’s appearance. Is the water clear, cloudy, full of algae. Next, water is graded on its chemistry levels. How much of each enzyme or mineral located in the water is extremely important. Any changes in any of these factors can change the water’s environment overall and therefore change how life in the water is.

In situ imaging and proteome profiling indicate andrographolide is a highly promiscuous compound. Lin Li et al (2015), Scientific Reports http://dx.doi.org/10.1038/srep11522 Natural products represent an enormous source of pharmacologically useful compounds, and are often used as the starting point in modern drug discovery. Many biologically interesting natural products are however not being pursued as potential drug candidates, partly due to a lack of well-defined mechanism-of-action. Traditional in vitro methods for target identification of natural products based on affinity protein enrichment from crude cellular lysates cannot faithfully recapitulate protein-drug interactions in living cells. Reported herein are dual-purpose probes inspired by the natural product andrographolide, capable of both reaction-based, real-time bioimaging and in situ proteome profiling/target identification in live mammalian cells. Our results confirm that andrographolide is a highly promiscuous compound and engaged in covalent interactions with numerous previously unknown cellular targets in cell type-specific manner. We caution its potential therapeutic effects should be further investigated in detail.

Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Geomechanics (from the Greek prefix geo- meaning "earth"; and "mechanics") involves the geologic study of the behavior of soil and rock. The two main disciplines of geomechanics are soil mechanics and rock mechanics. The former deals with the behaviour of soil from a small scale to a landslide scale. The latter deals with issues in geosciences related to rock mass characterization and rock mass mechanics, such as applied to petroleum industry or high depths, tunnel design, rock breakage, and rock drilling. Many aspects of geomechanics overlap with parts of geotechnical engineering, engineering geology, and geological engineering. Modern developments relate to seismology, continuum mechanics, discontinuum mechanics, and transport phenomena. In the petroleum engineering industry, geomechanics is used to predict important parameters, such as in-situ rock stresses, modulus of elasticity, leak-off coefficient and Poisson's ratio. Reservoir parameters that include: formation porosity, permeability and bottom hole pressure can be derived from geomechanical evaluation. The geotechnical engineer or geophysicist relies on various techniques to obtain reliable geomechanical models. These techniques that have evolved over the years, are: coring, log analysis; well testing methods like hydraulic fracturing, and geophysical sonar methods such as acoustic emission.

Data staging for in-situ processing and parallel IO/Coupling of HPC applications, John Biddiscombe
 
33:34
John Biddiscombe and Jerome Soumagne presents techniques for data staging for in-situ processing and parallel IO/Coupling of HPC applications. Parallel IO is used by HPC applications to quickly export data to disk, but the time/space taken to save and reload the results for post-processing is often prohibitive and so data-staging is emerging as a necessary and convenient method of holding data temporarily so that reduction operations can take place using post-processing tools. In this talk we discuss staging methods/libraries and how they have been used at CSCS for coupling of simulation and analysis for computational steering, and the future developments planned to cope with the ever growing size of data produced by simulations.
