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

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

Hi,Paul:
    I change this line:
    mpiexec -np $2 ./nek5000 > $1.log.$2 &
   to

   mpiexec -n $2 ./nek5000 > $1.log.$2 &
   in nekbmpi and then changed the name to 'runnek' in each node
   Then type ./runnek xxx 48
   While the error still exsits.

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
