[gmx-users] parallel problem

[Yuguang Mu]

I do use
 mpirun -c 2 mdrun -np 2  -s mini
But the problem is the same :

Back Off! I just backed up mini.log to #mini.log#
Reading file mini.tpr, VERSION 3.0.5 (single precision)
Reading file mini.tpr, VERSION 3.0.5 (single precision)
Fatal error: run input file mini.tpr was made for 2 nodes,
             while mdrun expected it to be for 1 nodes.
