[gmx-users] GPU not found

[Albert]

Now the problem solved now after I reinstall NVIDIA driver. When I run in
single GPU, it works fine. However, when I try to run :

mpirun -np 2 mdrun_mpi -s test.tpr

it failed with messages:
[mpiexec at cudaA.compuBio] HYDU_getfullhostname
(./utils/others/others.c:136): getaddrinfo error (hostname: cudaA.compuBio,
error: Name or service not known)
[mpiexec at cudaA.compuBio] HYDU_sock_create_and_listen_portstr

[mpiexec at cudaA.compuBio] main (./ui/mpich/mpiexec.c:877): process manager

I am using intel mpi...........

thank you very much.

Albert
