Hi, Do you have multiple versions of MPICH2 installed in your (user) system? MPICH2 implementation on Windows does not support installing multiple versions of the suite in the same system. Regards, Jayesh ----- Original Message ----- From: "Robert Bauer" <[email protected]> To: [email protected] Sent: Monday, November 26, 2012 1:20:15 AM Subject: [mpich-discuss] FW: MPICH2 matters Dear sirs: I find that in the windows environment some of the users of our software that uses MPICH2 may have more than one version of MPICH2 installed on their system. Therefore I am not aware of where the smpd.exe that is presently loaded comes from. If my software launches the incorrect mpiexec, then a version mismatch notice is given. Is there a way to enquire which version of smpd.exe is loaded at any time? smpd -version only gives the version that is closest in the PATH environment variable, and is not necessarily the one that is loaded.
