Dear all,
We have installed cuda 5.5 on our computer and compiled it successfully
with amber12 and ambertools13. When we run the command pmemd.cuda, we can
see that the simulation is running. however when we write nvidia-smi, we
get the following output
+------------------------------------------------------+

>From this we see that the GPU memory is not being used. What has gone wrong
here or what are we not doing so that the CUDA GPU works?
Thank you
