[mpich-discuss] Random Aborts in An MPI Program

[Balaji, Pavan]

Mark,

Sorry, 1.0.6 is too old for us to help you here.  It might be a bug that was resolved a long time ago.

You can install mpich in your home directory.  You don’t need root permissions to install it.  Please see the README for such instructions.

Regards,

  — Pavan
