Strudel ja CUDA

Meie serveris strudel on installeeritud tarkvarapakett NVIDIA CUDA Tookit ver. 5.0.35 koos samplitega

server strudel sisaldab kasutamiseks kolme CUDA graafikakaarti

graafikakaartideks on Club3D GT610 1024MB PCI-E 1x

graafikakaartide GPU on NVIDIA Geforce GT 610 1024MB mäluga, iga GPU sisaldab 48 CUDA coret, CUDA Compute Capability on 2.1

toolkiti ja samplite asukoht süsteemis ning muudatused mida tuleb environmenti teha et seda kasutada on nähtavad allpool olevast install-logi kokkuvõttest
