[mpich-discuss] [mpich2-dev] I can not make MPI recognizes a dual core

Tue May 25 13:42:46 CDT 2010

Hi,
Yes, I modified the default SMPD passphrase provided in the user input
textbox. The error is because I modified the passphrase or because I
provided an incorrect passphrase at the command line? Maybe I provided
an incorrect passphrase at the command line, maybe I should to
reinstall the MPICH2 and annotate the passphrase.
Thanks very much.

>  During the installation process, the MPICH2 installer requests for the SMPD passphrase. A default SMPD passphrase is provided in the user input textbox for convenience. Did you delete/remove the default passphrase during the installation step ?
>  Can you reply with details the steps used to install MPICH2 (You can add inputs to the installation steps that I provided in my previous email)? Also specify, in detail, if you modified any default input values during the installation process.
