[gmx-users] Cuda not detected

[Ye MEI]

try 
nvidia-smi -a
to see whether the GPU card has been correctly configured. 
This happens on my GPU node. Every time I reboot the computer, I must reconfigure the GPU cards with "nvidia-smi -a" using root account.

Hey,
I am playing with the gpu version of mdrun and could make it run with:
~/gromacs/gpu/bin/mdrun-gpu -s topol.tpr -device  
"OpenMM:platform=Cuda,memtest=15,deviceid=0,force-device=yes"
However after reboot of the machine ( which is a testing machine)
I get the following error:
-------------------------------------------------------
Program mdrun-gpu, VERSION 4.5.5
Source code file: /home/weber/gromacs/gromacs-4.5.5_gpu/src/kernel/ 
openmm_wrapper.cpp, line: 1272
Fatal error:
The requested platform "Cuda" could not be found.
echo $LD_LIBRARY_PATH:/opt/software/ganglia-3.1.7/lib64:/opt/software/ 
htop-0.8.3:/usr/local/cuda/lib64:/usr/local/cuda/lib:/home/weber/ 
OpenMM3.1.1-Linux64/lib

lib/mit/sbin:.:/usr/local/cuda/bin:/home/weber/cmake-2.8.6/bin
I run a simple gpu test program and it  works.
I believe something is not linked correctly, maybe someone can give me  
a hint.
Thank You
Andrzej
