Running UDFs in parallel

Emre Turkoz · February 1, 2011, 07:03

Hi,

I wanted to calculate PMV & PPD, namely some runtime additional variables with my analysis. To do that, I had to compile a Fortran file, usr_pmvppd.F, modify ccl and put it into CFX etc. I'm fine with all that. The only problem is that I can't run it in parallel. Serial solution works. Should we include an extra expression while compiling usr_pmvppd.F as in the case of double precision: cfx5mkext -double?

Thank you very much for your help.

Try to set up an identical case without your UDFs, then make a partition file and set up your case including UDF with using this partition file.

Hope this will help.

Thank you, Claudia.

I found out where my mistake lies. I tried to use MPICH2 protocol but the ccl file of cfx5mkext is in the way that MPI parallelization should be used.

Best Regards,
Emre.
