All, This is with great pleasure that the Open MPI ULFM team announces the new release candidate for ULFM 2.0. [https://bitbucket.org/icldistcomp/ulfm2/get/ulfm2.0rc.tar.bz2] The focus for ULFM 2.0 has been toward integration with current Open MPI master, performance, and stability. - ULFM is now based upon Open MPI master branch (#689f1be9). - Fault Tolerance is enabled by default and is controlled with MCA variables. - Added support for multithreaded modes (MPI_THREAD_MULTIPLE, etc.) - Added support for non-blocking collective operations (NBC). - Added support for CMA shared memory transport (Vader). - Added support for advanced failure detection at the MPI level. Implements the algorithm described in "Failure detection and propagation in HPC systems." <https://doi.org/10.1109/SC.2016.26>. - Removed the need for special handling of CID allocation. - Non-usable components are automatically removed from the build during configure - RMA, FILES, and TOPO components are enabled by default, and usage in a fault tolerant execution warns that they may cause undefined behavior after a failure. - Bugfixes, bugfixes, bugfixes As usual, you can find more information on [http://fault-tolerance.org/2017/11/03/ulfm-2-0/] or on the (new*) project repository [https://bitbucket.org/icldistcomp/ulfm2/overview] Happy Hacking, The Open MPI ULFM team. * the ULFM1 repository will go into archival mode.
