CERFACS Massively Parallel Resources

One of major issue to prepare codes to petaflop resources needs to adapt them on massively parallel servers.

CERFACS' Blue Gene server is representative of this kind of resources :

11.4 peak Tflops - 1.5 TB memory.
4096 Compute Cores (IBM PowerPC processor).
32 IO Nodes adressing 2 GPFS servers.

XL Fortran, XL C, XL C++, ESSL.
Blue Gene server allow CERFACS' researchers an efficient usage of our high parallel softwares on an high scalable supercomputer.
