Debugging MPICH Applications
NOTE >> In many cases, you can bypass the procedure described in this section. For more information, see Debugging MPI Programs. |
To examine Message Passing Interface/Chameleon Standard (MPICH) applications, you must use MPICH version 1.2.5 or later on a homogenous collection of computers. If you need a copy of MPICH, you can obtain it at no cost from Argonne National Laboratory at
https:// www.mcs.anl.gov/mpi. (We strongly urge that you use a later version of MPICH.)
The MPICH library should use the ch_p4, ch_p4mpd, ch_shmem, ch_lfshmem, or ch_mpl devices.
• For networks of workstations, the default MPICH library is ch_p4.
• For shared-memory SMP computers, use ch_shmem.
• On an IBM SP computer, use the ch_mpl device.
The MPICH source distribution includes all these devices. Choose the device that best fits your environment when you configure and build MPICH.
