All releases of LAM/MPI
Release Notes: Man page cleanups. Fixes for when tkill is not in the default location. A fix for hangs in 64-bit builds on Mac OS X systems. Localhost searches have changed to 127.0.0.0/8. Support for Fortran types MPI_REAL{4,8,16} for predefined floating point operations. A compile error in "ib" RPI, a problem with MPI_COMM_ACCEPT on Fedora Core 4, name clashes with FreeBSD symbols, Cygwin installation symlinks, an issue with hostfile comments, and Totalview shared object support on OS X have been fixed. The restart logic in the "self" CR module has been cleaned up. A lot of checkpoint/restart documentation has been added.
Release Notes: This release is comprised of a rollup of incremental bugfixes and compiler updates since version 7.1.1. The most noticable change will be the updates to support modern versions of common compilers by updating configure tests and upgrading to the latest version of GNU Libtool. This release adds RHEL4 RPMs and an OS X Universal package for Tiger/10.4.
Release Notes: Minor bugfixes were made along with an upgrade to libtool 1.5.8.
Release Notes: A variety of new modules were added, including Infiniband point-to-point, shared memory collectives, and SLURM. Upgraded or fixed modules include Myrinet (1.6, 2.0.x), BProc (v4.0), and MagPIe collectives. New MPI-2 collectives (intercommunicators, EXSCAN, and ALLTOALLW) and MPI-2 datatypes (MPI_INTEGER[1|2|4|8] and MPI_REAL[4|8|16]) were added. "mpi_hostmap" functionality was added for users with multiple TCP networks. SSI modules can now be loaded dynamically at run-time instead of compiled into the MPI library.
Release Notes: An obscure race condition that occurred when running over 255 nodes was fixed along with a rare upper/lower bound datatype calculation error. MPI_IGNORE_ERRORCODES was changed to have correct casting, and TCP socket buffer run-time sizing was corrected. The interface detection code was reworked to allow arbitrary numbers of network interfaces, and fixes were made for TM (PBS), Solaris, and Sun Grid Engine. Some documentation and help messages were corrected.
Release Notes: This version allows resizing of fd_sets on platforms that support it. Timeouts in the lamd code were fixed. Missing SYSV libraries were added on platforms that need it. g77 is sought before f77 when looking for the default Fortran compilers.
Release Notes: This version fixes a broken libtool 1.5 test, does not propagate $LAM_MPI_SESSION_PREFIX, and fixes a minor blcr checkpoint/restart errors. It allows resizing of fd_sets on platforms that allow it, fixes timeouts in the lamd code, adds missing SYSV libraries on platforms that need it, and looks for g77 before f77 for the default Fortran compilers.
Release Notes: The 7.0.1 release accidentally did not include the Myrinet (gm) RPI module. This release fixes that issue.
Release Notes: This version adds support for Myrinet gm 2.0.x and fixes a number of small compile-time and run-time errors on a variety of different systems and compilers.
Release Notes: Introduction of the System Services Interface (SSI) extensible component architecture, allowing run-time selection of the underlying network transport layer, setting of many run-time tunable parameters, and 3rd party plugins to the LAM and MPI run-time environments. Native support for Myrinet networks. Native support for RSH/SSH, PBS, BProc, and Globus run-time environments. New SMP-optimized collective algorithms. New support for checkpoint/restart of parallel MPI jobs (when used with the Berkeley Labs Checkpoint/Restart package). New support for the Etnus TotalView parallel debugger.
