The Open MPI Team, representing a consortium of research, academic, and industry partners, is pleased to announce the release of Open MPI version 1.7.3. As usual, the release is available from the OpenMPI web site:
http://www.open-mpi.org/software/ompi/v1.7/ This is a joint bug-fix and feature release within the 1.7 feature release series. - Make CUDA-aware support dynamically load libcuda.so so CUDA-aware MPI library can run on systems without CUDA software. - Fix various issues with dynamic processes and intercommunicator operations under Torque. Thanks to Suraj Prabhakaran for reporting the problem. - Enable support for the Mellanox MXM2 library by default. - Improve support for Portals 4. - Various Solaris fixes. Many thanks to Siegmar Gross for his incredible patience in reporting all the issues. - MPI-2.2: Add reduction support for MPI_C_*COMPLEX and MPI::*COMPLEX. - Fixed internal accounting when openpty() fails. Thanks to Michal Peclo for reporting the issue and providing a patch. - Fixed too-large memory consumption in XRC mode of the openib BTL. Thanks to Alexey Ryzhikh for the patch. - Add bozo check for negative np values to mpirun to prevent a deadlock. Thanks to Upinder Malhi for identifying the issue. - Fixed MPI_IS_THREAD_MAIN behavior. Thanks to Lisandro Dalcin for pointing out the problem. - Various rankfile fixes. - Fix functionality over iWARP devices. - Various memory and performance optimizations and tweaks. - Fix MPI_Cancel issue identified by Fujitsu. - Add missing support for MPI_Get_address in the "use mpi" TKR implementation. Thanks to Hugo Gagnon for identifying the issue. - MPI-3: Add support for MPI_Count. - MPI-2.2: Add missing MPI_IN_PLACE support for MPI_ALLTOALL. - Added new usnic BTL to support the Cisco usNIC device. - Minor VampirTrace update to 18.104.22.168. - Removed support for ancient OS X systems (i.e., prior to 10.5). - Fixed obscure packing/unpacking datatype bug. Thanks to Takahiro Kawashima for identifying the issue. - Add run-time support for PMI2 environments. - Update openib BTL default parameters to include support for Mellanox ConnectX3-Pro devices. - Update libevent to v2.0.21. - "ompi_info --param TYPE PLUGIN" now only shows a small number of MCA parameters by default. Add "--level 9" or "--all" to see *all* MCA parameters. See README for more details. - Add support for asynchronous CUDA-aware copies. - Add support for Mellanox MPI collective operation offload via the "hcoll" library. - MPI-3: Add support for the MPI_T interface. Open MPI's MCA parameters are now accessible via the MPI_T control variable interface. Support has been added for a small number of MPI_T performance variables. - Add Gentoo memory hooks override. Thanks to Justin Bronder for the patch. - Added new "mindist" process mapper, allowing placement of processes via PCI locality information reported by the BIOS. - MPI-2.2: Add support for MPI_Dist_graph functionality.
