I have a complicated problem with FLUENT 13 MPI. I open the projects (cas, which was created and results which were obtained (dat) on another computer with version 12.1 of FLUENT and get a message:

I mean this is a problem with starting MPI (hp-mpi or intel mpi). On another computer I didn't have such errors with this files.
The firewall on the compure is turned off.

The same problem I have if I use versions 12.1 and 6.3.26. Without any differense.
I tried to update hp-mpi from HP site and get version 8. But it did not solve my problem.
I tried to reinstall OS (W7 x64) and ANSYS (13 and 12.1), but errors were the same.
I believe that core i7 k2600 on ASUS P8P67 had some incompatibility with ANSYS software when MPI used.

Hi Taurus,

I am currently a PhD student and will shortly be purchasing a computer with the i7 2600k processor (although with a intel motherboard) with the intention of running Ansys CFX 12.1 and probably OpenFOAM. I was just wondering if you had resolved this issue or know whether or not it is a compatibility issue with the processor specifically? It'd be a nightmare if I couldn't parallel process on it! One possible solution is to switch off the hyperthreading in the bios. I have seen CFX 11 working fine on an earlier version of the i7.
