mpiP v3.1.0 release

We are pleased to announce the release of version 3.1.0 of the mpiP lightweight profiling library for MPI applications.

Release v3.1 addresses the following issues:

* Configure defaults to the optimal platform timer, but the timer can be specified with configure options.
* Support for rts_get_timebase on BG/L.
* Runtime flags can be used to specify that report generation be done by a single collector process (default) or by using a small fixed amount of memory and MPI collectives. The single collector process approach tends to be faster while the low-memory approach is useful for systems where memory availability may be a concern.

Release v3.0 addresses the following issues:

* New reporting formats with summary statistics ( See runtime options 'c' and 'v' ).
* New reporting algorithms to reduce memory requirements ( See configure flag --use-low-mem-report ).
* MPI_Pcontrol calls can reset statistics, generate multiple reports per run, and generate reports in various formats.... read more
