We are pleased to announce the second beta release of Casper (version 1.0b2), a portable process-based asynchronous progress model for MPI communication. It contains several new features and bug fixes over the previous release.

http://www.mcs.anl.gov/project/casper/downloads/

A list of changes:

- Offloading-based asynchronous progress for MPI non-blocking two-sided
  (point-to-point) communication.

- Performance profiling summary.

- Hwloc based locality optimization.

- Set CSP_NG=0 to fully disable Casper wrapping routines.

- BUG FIX: Support error handler for COMM_SELF, inter-communicator.

- BUG FIX: Fixed incompatible code with OpenMPI.

Details of each change can be found in CHANGES (https://github.com/pmodels/casper/blob/master/CHANGES).

Regards,
The Casper Team
