I believe the problem is related to Ubuntu providing something wrong and not a bug mpich2. I have mpich2 working fine on SL6. I will try to compile my own mpich2 installation on ubuntu and re-test on again and return back.
I just have bad flu now,, so it might take a week or so before I can return back with more detailed information. But as I pointed out before, this seem to have happened to a person before who updated his libraries but not mpich2 installation. (as far as I understand from the thread I mentioned in my first post). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1045326 Title: using valgrind with mpirun causes problems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mpich2/+bug/1045326/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
