MPIEXEC parallization not working on windows 7

[Shatendra]

We are using 12.8.2 on windows 7. As a single core application it runs well but fails if we try to run mpiexec. It fails some time in redhat too. Can some one suggest if there is a licensing problem or OS related problem?

Licensing possibly, you need to have "ATKSlave" features in your license to run in MPI parallel. But as long as you have that, ATK is extensively tested to work in parallel on both Windows and Linux (although the Windows MPI environment is rare).
