[mpich-discuss] MPICH2 and GPU

[bob ilgner]

Dear All,

I have two GPUs on 1 motherboard and want to use MPI to control the
CUDA on each GPU.

Program runs well in Windows 7 environment without MPICH2

When using "mpiexec -n 2 progname" then the CUDA error calls tell me
"no CUDA-capable device is detected".

i.e. the error only arises in the MPI environment.

Has anyone else experienced this before and is there something I need
to do with Mpich2 to be able to detect the GPUs ?

Regards, bob
