e-Science
Glossary
Ensemble
Running a computer model many times, each time slightly varying one or more parameters.
Grid computing
Using the resources of many separate but connected computers (usually via the internet) to simultaneously solve a problem.
Grid computing makes it possible for scientists to run a huge number of tasks (jobs) at once. For example they can carry out thousands of similar computations, with many different temperatures and pressures. If scientists want to fully exploit grid computing, they need to submit jobs to multiple computers in different locations. To make this easy from a desktop computer, the eMinerals team developed a new system to easily submit thousands of similar jobs and collate the information.
Grid tools
The tools used for grid computing (see above).
High level nuclear waste
British nuclear fuels defines this as waste which is radioactive enough to generate heat. This waste is what remains when the uranium and plutonium have been reprocessed. The high-level waste is concentrated by evaporation and stored inside double-walled stainless steel tanks inside thick concrete walls (encapsulation).
Terabyte
A terabyte is a trillion bytes or one thousand gigabytes.
