How to ues MSMPI in CONVERGE?

fcl · January 17, 2019, 00:47

hello,
I want to use MSMPI to realize parallel computing in win10, but when I entered command like usual but just change "mpich" to "msmpi", the system didn't give a respond. Please tell me what I can do to solve it. THX

Hi,

you need to enter "mpiexec" and not "msmpi".

See example: mpiexec-n 4 converge-2.4.23-msmpi-win64.exe

Hi,
Thanks for your reply. My cmd input is as follow:
"C:\Program Files\Microsoft MPI\Bin\mpiexec.exe" -wdir D:\angle30 -n 6 "C:\Program Files\CONVERGE2.2\converge-2.2.0-msmpi-windows-64-071614.exe"
Could you please tell me is there any problem?

Well, i am using Environment Variables in Windows, which is why my command is much shorter. I am opening the CMD in case setup folder as well.
Anyway, i tested your way:

"C:\Program Files\Microsoft MPI\Bin\mpiexec.exe" -wdir D:\CONVERGE\Example\CHT_pipe_flow -n 4 "C:\Program Files\CONVERGE\converge-udf-2.4.22-msmpi-win64.exe"

and it worked.
What type of response do you get?

It's strange because I didn’t get any response. As you can see, my solver is CONVERGE 2.2. I'll test it on CONVERGE 2.3. Thanks for your help.
