[RegCNET] 回复： Re : Need a help in parallel run of Regcm4

[黄河]

Hi Bamba and others,
 
Thanks for your help. The run command I used is "mpirun -np 4 /home/ghh/regcm/Bin/regcm regcm.in >regcm.out". The problem remains.
 
The program could run used the command like "./regcm regcm.in".
 
Thank you very much!

Hi

You just forgot to run you executable file. It should be something like:
mpirun -np 4 /home/ghh/regcm/Bin/regcmMPI regcm.in > regcm.out &

Cheers

There is a question when I continue running the command "mpirun -np 4 /home/ghh/regcm/Bin regcm.in >regcm.out". The error like the following.
---------------------------------------------------------------------
It seems that [at least] one of processes that was started with mpirun did not invoke MPI_INIT before quitting (it is possible that more than one process did not invoke MPI_INIT -- mpirun was only notified of the first one, which was on onde n0).
 
mpirun can *only* be used with MPI programs (i. e., programs that invoke MPI_INIT and MPI_FINALIZE). You can use the "lamexec" program to run non-MPI programs over the lambooted nodes.
----------------------------------------------------------------------
How to invoke MPI_INIT to all processes? Please help me out with this problem.
Thank you very much!
