The '''Distributed European Infrastructure for Supercomputing Applications''' ('''DEISA''') is a [[European Union]] [[supercomputer]] project. It is made up of a consortium of eleven leading national supercomputing centres from seven [[Europe]]an countries. It supportspromotes pan-European research by providing and operating a distributed supercomputing environment all over Europe and aims at delivering a turnkey operational solution for a futureon European [[high-performance computing]] systemsystems. By extending the European collaborative environment in the area of supercomputing, DEISA follows the suggestions of [[ESFRI]].

== History ==

The DEISA project started as DEISA1<ref>[http://cordis.europa.eu/search/index.cfm?fuseaction=proj.document&PJ_LANG=EN&PJ_RCN=9043360&pid=0&q=0B66388C6D78D5C148A0745B42BDAE57&type=sim DEISA1 on [[Cordis]]]</ref> in 2002 developing and supporting a pan-European distributed high performance computing infrastructure. The initial project was funded by the [[European Commission]] in [[Sixth Framework Programme|FP6]]. The funding continued for the follow-up project DEISA2<ref>[http://cordis.europa.eu/search/index.cfm?fuseaction=proj.document&PJ_LANG=EN&PJ_RCN=10069312&pid=0&q=552A6FB756E2670E450CDD0BC5BED465&type=sim Continued funding]</ref> in [[Seventh Framework Programme|FP7]].

The DEISA infrastructure couples the eleven national supercomputing centres which form the DEISA consortium with a dedicated (mostly 10Gbit10&nbsp;Gbit/s) network connection provided by [[GEANT2|GÉANT2]] on the European level and the [[NREN]]s on the national level.research Newand associateeducation partnersnetwork]]s will also be connected to this infrastructure(NRENs).

The DEISA infrastructure couples the eleven national supercomputing centres which form the DEISA consortium with a dedicated (mostly 10Gbit/s) network connection provided by [[GEANT2|GÉANT2]] on the European level and the [[NREN]]s on the national level. New associate partners will also be connected to this infrastructure.

==Deisa Benchmark Suite==

DEISA has produced a packaged [[benchmark (computing)|benchmark suite]] to help computer scientists assess the performance of parallel supercomputer systems. The benchmark comprises a number of real applications codes taken from a wide range of scientific disciplines. All the codes are packaged into a structured framework allowing compilation, execution and analysis to be configured and carried out via a set of standard input files.

The codes were chosen as representative of the scientific projects performed on the DEISA supercomputers. The codes and associated datasets have beenwere selected to be useful infor benchmarking systems with peak performances ranging up to hundreds of teraflops, machines which are more powerful than a desktop [[personal computer|] by factors of tens of thousands.

are more powerful than a desktop [[personal computer|PC]] by factors of tens of thousands.

The current suite containscontained codes relevant to [[astrophysics]], [[fluid dynamics]], [[climate modelling]], [[bioscience]]s, [[materials science]], [[nuclear fusion|fusion power]] and fundamental [[particle physics]]. It has been run by DEISA on a range of its own supercomputers and records of the results are kept for comparison.{{Where |date= August 2013}} The DEISA benchmark was used by the EU-funded PRACE project as a starting point for their investigations of benchmarks for the next generation of petaflop supercomputers.
