ReplayEngine 1.7

There are two big new features in ReplayEngine 1.7. The first is support for shared memory. This means that programs that take advantage (either directly or via libraries) shared memory for inter-process communication can now be recorded and replayed under ReplayEngine.

The second is backwards continue functionality. This means that you can now run right to a crash and then set breakpoints or watch points and "continue back" to the last time that one of the breakpoints or watchpoints would have been triggered.

This release also introduces support for the following MPI library configurations

* MPICH 2 Nemesis and SSM channels
* Shared memory configuration for OpenMPI, Intel MPI, HP MPI, and LAM MPI

These MPIs join MPICH2, MVAPICH2, Open MPI, Intel MPI, HP MPI, MPICH 1 and SGI's MPT library, which continue to be supported as they were in previous releases. It is perhaps worth noting that native ib-verb support on Infiniband is still something we are working on for a future release. In the meantime users with infiniband hardware are advised to consider configuring their MPI library for IP over IB usage.

This release also includes improved performance and stability when using ReplayEngine with multi-thread codes (using either OpenMP or pthreads).
