Hi, I am trying to run OpenCL code on a new "mini-cluster" machine (4 x AMD Opteron(tm) Processor 6380 (16 Cores)) and I obtain the following error when the

clGetPlatformId() function is reached:


Setting of real/effective user Id to 0/0 failed

FATAL: Module fglrx not found.

Error! Fail to load fglrx kernel module! Maybe you can switch to root user to load kernel module directly

Segmentation fault (core dumped)


I have tried both AMD APP SDK v2.8 and 2.9 without success, the machine has not AMD GPU (only a Matrox one), and I would like to use meanwhile

the AMD CPUs before buying a proper GPU for OpenCL development. Thanks for your help.
