[Panda, Dhabaleswar]

The MVAPICH team is pleased to announce the release of OSU
Micro-Benchmarks (OMB) 8.0rc.

The new features, enhancements, and bug fixes for OSU Micro-Benchmarks
(OMB) 8.0rc are listed here:

* New Features & Enhancements (since 7.5 series)
    - Fully rebuilt benchmarks on common template files.
                - Reduces variance between test code to facilitate easier
                  community contributions
                - Allows for single point of change contributions
    - Added unified OMB launcher for batch testing of pt2pt,
          collective, and RMA tests
                - Allows one-step run of some or all benchmarks of a given type
                - Configurable behavior allows for faster comprehensive benchmarking
                - Supports batch testing of some or all tests in a given category
                - Reports test failures or incompatible arguments on exit
                - Fully backwards compatible with existing scripts
                - Full details for using the launcher available in README
    - Added support for colored terminal output for enhanced visual output

* Bug Fixes (since 8.0b)
    - Restored build compatibility with MPI implementations that do not
      provide MPI-3 features.
    - Fixed incorrect tail and graph metrics in one-sided benchmarks.
    - Fixed hangs and incorrect communication in multi-threaded latency and
      multiple-buffer congestion benchmarks.
    - Fixed OpenACC point-to-point validation builds and accelerator barrier
      buffer allocation.
    - Fixed process shape detection causing exit before printing usage in some
      benchmarks.
        - Thanks to Ofir Michael @ NVIDIA for the report
    - Fixed unrecognized -T arguments silently falling back to the default
      datatype.
        - Thanks to Ken Raffenetti @ Cornelis Networks for the report
    - Improved launcher option validation, diagnostics, and repeated benchmark
      execution.
    - Disabled color output by default to prevent escape sequences in redirected
      output. Color output can still be enabled at configure time or runtime.
    - Improved validation for one-sided accumulate and atomic benchmarks.
    - Fixed several build, installation, and memory management issues found
      during beta testing.
