[Nek5000-users] How to run Nek5000 in cluster based on mpich?

[nek5000-users at lists.mcs.anl.gov]

Hi, Paul:
     I read the nekbmpi file and find this:
    mpiexec -np $2 ./nek5000 > $1.log.$2 &
    so the nek5000 is executed by mpi. In mpich, the common way to run a executable program can be run as :
    mpiexec -n XX ./nek5000

    However, when I type this:
    mpiexec -n 32 ./nek5000 > turbChannel.log &
    error returns like:
     Fortran runtime error: File './NEK.rea' does not exist
Best reguards

Hi Xianbei,


Have a look at the nekbmpi script and modify to match the job submission
procedure on your cluster.

Hi,all:
   I have just built a small cluster of computers, based on mpich.I have tested the capability of this cluster, each node can be called freely.  Now I want to do my simulation in it, however, I don't know how to run Nek. As known, on only 1 computer, one can do like this:
  nekmpi XXX X
or
  nekbmpi XXX X
  while this is not the case in the cluster! I believe most of you have tried this, I'll appreciate if anyone can give me some advice.
Best regards
Xianbei
