We are pleased to announce the beta release of OSHMPI-2.0 (version 2.0b1), a portable OpenSHMEM implementation on top of MPI. It contains several key features.<br>
<br>
<a class="moz-txt-link-freetext" href="http://www.mcs.anl.gov/project/oshmpi/downloads/">http://www.mcs.anl.gov/project/oshmpi/downloads/</a><br>
<br>
A list of features:<br>
<br>
- Full support of OpenSHMEM 1.4 specification.<br>
<br>
- Function inline for all OSHMPI internal routines.<br>
<br>
- Caching internal MPI communicators for collective operations with PE active set.<br>
<br>
- OpenSHMEM multithreading safety support.<br>
<br>
- Active message support of OpenSHMEM atomic operations. MPI accumulates cannot be directly used because MPI does not guarantee atomicity between different reduce operations.<br>
<br>
- Optional asynchronous progress thread support for active message based atomic.<br>
<br>
Details of each feature can be found in CHANGES (<a class="moz-txt-link-freetext" href="https://github.com/pmodels/oshmpi/blob/master/CHANGES">https://github.com/pmodels/oshmpi/blob/master/CHANGES</a>).<br>
<br>
Regards,<br>
The OSHMPI Team<br>
