RE: [gmx-users] problem of paralleled running
Can't help you directly, other than suggestion you provide a lot more information than you have. Direct copy/paste of the command lines used, error messages and log files generated, how GROMACS was installed etc. Catch ya, Dr. Dallas Warren Medicinal Chemistry and Drug Action Monash Institute of Pharmaceutical Sciences, Monash University 381 Royal Parade, Parkville VIC 3010 dallas.war...@monash.edu +61 3 9903 9304 - When the only tool you own is a hammer, every problem begins to resemble a nail.

Could someone help me figure it out? Thanks very much! Gromacs 4.5.1 is somewhat viral on cpu (takes all of them if not told otherwise). I you submit multiple jobs to a node without telling gromacs (ie. mdrun) how many cpus to use, all the jobs will use all the cpus simultaneously. This can cause job failure. If you use SGE, you may want to use SMP or MPI.
