Many thanks in advance |

But I have problems with using Platform MPI on Supermicro server with Windows Server 2008 r2 (mpid.exe crashes) while Intel MPI works well. |

Then find main differences between 'em (hardware + software) and it may give you a cause. Maybe there is a software that interfere or conversely you missed something.

Platform MPI should work fine with windows 7, I'm guessing there is a firewall issue with the one computer that isn't working. You may have to open the MPI port in the firewall:
Also add firewall exceptions for MPI: On the Windows Firewall dialog box, click the Exceptions tab and then click Add Program. Browse to the following programs: • For Platform MPI: – <ANSYS Inc installation path>\v150\CFX\bin\<CFX5OS>\solver-pcmpi.exe – <ANSYS Inc installation path>\v150\CFX\bin\<CFX5OS>\double\solverpcmpi.exe – <ANSYS Inc installationpath>\v150\commonfiles\MPI\Platform\<v ersion number>\winx64\sbin\pcmpiwin32service.exe – <ANSYS Inc installation path>\v150\commonfiles\MPI\Platform\<version number>\winx64\bin\mpirun.exe – <ANSYS Inc installation path>\v150\commonfiles\MPI\Platform\<version number>\winx64\bin\mpid.exe Did you install platform MPI? Have you run the MPI test program? Local MPI Test: Make a folder called "temp" in c:, it may already exist. Run the following command in cmd: Change to c: then type: cd\temp. Then Type: "C:\Program Files\ANSYS Inc\v150\ansys\bin\winx64\ansys150.exe" -np 2 -mpitest Like I said, you may have to open the MPI port in the firewall for both inbound and outbound traffic. |

What is the problem? Can you be more specific? Did you run MPI test? Is the MPI service running?

The way Platform MPI starts in startmethods.ccl uses some type of process pinning that doesn't work with larger Intel v3 processors. You need to delete affwidth and affcycle.
With v17 Intel MPI works much faster anyways on our cluster. |
