Hello users,

Thanks Ron Rahaman that was much helpful.

I am having redhat linux workstation and I have downloaded openmpi in it to run it parallel

I typed ./nekbmpi eddy_uv 4 I getting different error it says p= 4 has passed but not compiled with DMPI. I have no clue what does that mean.

I have attached screen shot of the error(screen shot 5)

Thanks,

Mansi Patel

Hello Users,

I have Redhat linux workstation, I have already compiled code with nekb by making changes in makenek file, but now I want to run it parallel. At first when I compiled it by making F77 = mpif77 and cc= mpicc and commenting IFMPI ="false" I got errors that mpi not found than I installed openmpi

Now when I compile using makenek it gets compiled successfully but when I try to run it using nekbmpi i get errors like

mv: cannot stat `eddy_uv.sch': No such file or directory
and sometimes if i do ./nekbmpi eddy_uv 4 it and put enter i get no errors on first time but if i enter again for second time I get same error that is mv: cannot stat `eddy_uv.sch': No such file or directory
I want to understand what mistake I am doing and what should I do to get rid of errors and also which file can help me to see whats going on in simulation

Thanks,
Mansi Patel

Hi Mansi,

I suspect that you can safely ignore the error.  The error probably comes
from line 7 of the "nekbmpi" script:
mv $1.sch $1.sch1
This command is intended to move the .sch file from a previous run, in case
there's one in your directory. If this is your first run, there will be no
.sch file in your directory, and the "mv" command will give the error you
saw. So it probably doesn't indicate a problem.

Best,
