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

[黄河]

Hi Bamba and others,
 
Bamba, you have got it. There are some wrong when I compile the program. All the errors when compile the program is attached in a DOC file. 
 
Some basic operation system information of my computer:
1. Red Hat Enterprise Linux WS release 3 (Taroon Update 2)
2. PGI 7
3. NetCDF 4
4. MPI
 
Whether is because the system is not compatible with the RegCM4?
 
Much obliged!
 
Huanghe Gu

As far as I remember, there should not be any "regcm" in your Bin directory. If you compiled in Serial, you should find regcmSerial, if in parallel regcmMPI. May be Your program did not run because either you compiled it in serial or you did not provide the right executable.

Cheers !

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!
