NOTES:

xt-mpt
The following features were added to MPT 5.2.0 over MPT 5.1.4:
- This new version is based on MPICH2 1.3a2 and includes numerous
fixes. It also includes some additional error checking. One class
of these errors involves the use of MPI_IN_PLACE. Some users may
find that using the MPICH_NO_BUFFER_ALIAS_CHECK environment
variable is a useful workaround until their application can be
corrected. See the intro_mpi man page for more information
concerning this environment variable.

In addition the following features were added in MPT updates since
the MPT 5.1.0 release and are also included:

- If a consistent ordering of the reduce operation is needed for
bitwise reproducibility, regardless of system configuration, two
new environment variables have been added to allow that. They are
MPICH_ALLREDUCE_NO_SMP and MPICH_REDUCE_NO_SMP and are described
further in the intro_mpi man page.

- Improvements to MPI-IO collective buffering.

- A check is now made during SHMEM initialization to detect
potential oversubscription of memory, and if detected, the
layout of the memory regions is printed. In addition, a new
environment variable, SHMEM_MEMINFO_DISPLAY, causes SHMEM to
display the layout even if oversubscription is not detected.
See the SHMEM_MEMINFO_DISPLAY environment variable in the
intro_shmem man page for more information.
