[gmx-users] not running on higher no of nodes

[Anupam Nath Jha]

Dear all

My job is running successfully on 32no of nodes (gromacs-3.3.3) of Rocks 4.3, 33
node cluster ( Dual processor, Quad core Intel Xeon: Total 264 cores ), but if I
am submitting same job for 64or higher no of nodes. it's coming without doing
anything.
this is my command line:

grompp_mpi -np 64 -f run.mdp -p topol.top -c pr.gro -o run.tpr
mpirun -machinefile ./machfile1 -np 64 mdrun_mpi -v -deffnm run

what's going wrong.

regards
anupam
