I'm still looking for the new "-11" option that will allow OpenMPI compiled code to run even faster. I'm hoping that option makes it in soon (isn't it part of the 11.7 MPI standard?)

This release is essentially a complete rewrite of Open MPI based on new technologies such as C#, Java, and object-oriented Cobol (so say we all!). Buffer overflows and memory leaks are now things of the past. We strongly recommend that all users upgrade to Windows 7 to fully take advantage of the new powers embedded in Open MPI. This version can be downloaded from the The Onion web site or from many BitTorrent networks (seeding now; the Open MPI ISO is approximately 3.97GB -- please wait for the full upload). Here is an abbreviated list of changes in Open MPI 2009 as compared to the previous version: - Dropped support for MPI 2 in favor of the newly enhanced MPI 11.7 standard. MPI_COOK_DINNER support is only available with additional equipment (some assembly may be required). An experimental PVM-like API has been introduced to deal with the current limitations of the MPI 11.7 API. - Added a Twitter network transport capable of achieving peta-scale per second bandwidth (but only on useless data). - Dropped support for the barely-used x86 and x86_64 architectures in favor of the most recent ARM6 architecture. As a direct result, several Top500 sites are planning to convert from their now obsolete peta-scale machines to high-reliability iPhone clusters using the low-latency AT&T 3G network. - The iPhone iMPI app (powered by iOpen MPI) is now downloadable from the iTunes Store. Blackberry support will be included in a future release. - Fix all compiler errors related to the PGI 8.0 compiler by completely dropping support. - Add some "green" features for energy savings. The new "--bike" mpirun option will only run your parallel jobs only during the operation hours of the official Open MPI biking team. The "--preload-result" option will directly embed the final result in the parallel execution, leading to more scalable and reliable runs and decreasing the execution time of any parallel application under the real-time limit of 1 second. Open MPI is therefore EnergyStar compliant when used with these options. - In addition to moving Open MPI's lowest point-to-point transports to be an external project, limited support will be offered for industry-standard platforms. Our focus will now be to develop highly scalable transports based on widely distributed technologies such as SMTP, High Performance Gopher (v3.8 and later), OLE COMM, RSS/Atom, DNS, and Bonjour. - Opportunistic integration with Conflicker in order to utilize free resources distributed world-wide. - Support for all Fortran versions prior to Fortran 2020 has been dropped. Make today an Open MPI day! _______________________________________________ users mailing list us...@open-mpi.org http://www.open-mpi.org/mailman/listinfo.cgi/users
