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 the sixth of the [[Sixth Framework Programme|Programmes for Research and Technological Development]] (FP6) from 2004 through 2008.<ref>{{Cite web |title= Distributed European Infrastructure for supercomputing applications |work= Project funding web site |publisher= [[CORDIS]] |url= http://cordis.europa.eu/projects/rcn/80148_en.html |accessdate= 13 August 2013 }}</ref> 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 10 Gbit/s) network connection provided by [[GEANT2|GÉANT2]] on the European level and the [[national research and education network]]s (NRENs).
