Dear all,

 

I wonder if you could help me with this question.

I have got 3 Linux servers with 8 processors on each server. If I want to run a job using mpirun command

and specify the number of processors to be used on each server. Is there any way to do this? At the moment,

I find that I can only issue such command “mpirun –np 14 –host cfd1,cfd2 ./wrf.exe’ which means the mpirun

Will run the job using 7 processors on each server cfd1 and cfd2. Can I specify say using 8 processors on cfd1 and

6 processors on cfd2? I ask this question because I found that the different combination of processors on those

Servers can influence the computation time dramatically. Thank you very much in advance,

 

Cheers,

 

Min Zhu
