Hi ROss:
thanks a lot for prompt reply.
I use *Intel^® Parallel Studio XE 2011 for Linux**
<
https://registrationcenter.intel.com/RegCenter/NComForm.aspx?ProductID=1540>
and mpich2-1.4.1. The MPI goes well for intel compiler. neither series
or MPI.CUDA works although I don't get any error when I compile tjhem.
It doesn't work when I try to submit for job running.... Yes, I submit
errors in previous thread, and here they are:
mpiexec -np 2 $AMBERHOME/bin/pmemd.cuda.MPI -i md.in -p bm.prmtop -c
npt.rst -o md.out -r md.rst -x md.mdcrd &
but it failed with following infomrations:
