The LAM Team from the Open Systems Lab at Indiana University is
pleased to release LAM/MPI version 7.0.
Representing over two years of development, version 7.0 includes
significant new features for MPI applications programmers, parallel
programming/MPI researchers, and system administrators. An
abbreviated listing of these features includes:
- When used with the Berkeley Lab Checkpoint/Restart (BLCR) single-node
checkpointer, parallel MPI jobs can be involuntarily checkpointed
and restarted.
- Low-latency, high-bandwidth message passing on Myrinet networks.
- Extensive run-time tuning and underlying network selection
(vs. compile-time selection and tuning).
- SMP-aware collectives. Based on the MagPIe algorithms, several of
LAM's MPI collective functions have been optimized for use in
networks of SMPs.
- Integration with PBS, BProc, and Globus. LAM now uses the native
job starting mechanisms of each of these environments to launch jobs
in parallel.
- A comprehensive User's Guide, providing a user-centric description
of LAM/MPI, how to use all of its features, and how to tune MPI
applications at run-time.
- An extensible component architecture such that MPI researchers can
write small, self-contained components that "plug-in" to LAM/MPI.
- Support for the TotalView parallel debugger.
More information and documentation is available at the
newly-redesigned LAM/MPI web site:
