Greetings!
The LAM team has released LAM/MPI 7.0b12 for testing. At present, all
known critical bugs for the 7.0 release have been solved (with the obvious
exception of documentation). We do not anticipate any major changes in
source code between 7.0b12 and the 7.0 release, unless issues are found
during testing. We invite you to try the beta release on your platform.
Downloads and information can be found at:
http://www.lam-mpi.org/beta/
As expected, this is *BETA* software -- there are likely still to be some
kinks. This is not for production use. The web page notes all issues we
are aware of - if you find something, please let us know on the LAM
mailing list.
New features in LAM 7.0 include:
* Run-time selectable RPI drivers
* Support for Myrinet/gm networks
* TotalView parallel debugger support
* Support for booting LAM using the PBS TM extensions
* Support for running LAM under BProc environments
* Support for checkpoint/restart using the BLCR checkpoint/restart
package
* More complete C++ bindings
* Upgraded ROMIO MPI I/O package
* Support for MPI_THREAD_FUNNELED and MPI_THREAD_SERIALIZED
Known issues in the 7.0b8 release include:
* Documentation is still rough - please bear with us.
* TotalView support on Solaris may require special compiler
flags - in particular, for some versions of the Forte compilers,
you may have to use the configure option
--with-tv-debug-flags="-g -W0,-y-s"
to work around a bug in the Forte compiler suite.
* It appears that Libtool is unable to reliably build shared
libraries using the Forte compilers on Solaris. We have not
been able to find a work-around for this problem.
Documentation is available in the doc directory of the tarball as two PDF
files: an Install Guide and User's Guide. At present, the Install
Guide is not polished, but should contain everything you need to know
about building and installing LAM/MPI. If you find some missing content,
please let us know. The User's Guide is still very much a work in
progress, but feel free to comment on that as well.
The checkpoint/restart functionality in LAM/MPI is only available if you
have the Berkeley Labs Checkpoint/Restart (BLCR) package installed.
Unfortunately, this package is not publically available at this time. We
will post information to the LAM mailing lists when the package becomes
available for public download.
