OFED 1.2 April 16 meeting summary
Main decisions:
1. RC2 will be ready on the US morning of Wed April 18. (RC2 date is
derived from Intel schedule for the 256 nodes cluster)
2. RC3 due date is April 26.
3. All release notes and other documents should be ready for RC3
Hi Tziporet. I am not sure who handles the release notes, but we need to
add release notes for MVAPICH2. I've attached an
mvapich2_release_notes.txt file that is similar to the files in the
docs/ subdirectory of the OFED RC2 release. Can this be added?

Open Fabrics Enterprise Distribution (OFED)
MVAPICH2-0.9.8 in OFED 1.2 Release Notes
April 2007
Overview
--------
These are the release notes for MVAPICH2-0.9.8. This is OFED's edition of
the MVAPICH2-0.9.8 release. MVAPICH2 is an MPI2 implementation over
InfiniBand from Ohio State University (OSU)
(http://nowlab.cse.ohio-state.edu/projects/mpi-iba/).
Software Dependencies
---------------------
MVAPICH2 depends on the installation of the OFED Distribution stack with
OpenSM running. The MPI module also requires an established network
interface (either InfiniBand, IPoIB, or Ethernet). BLCR support is needed
if built with fault tolerance support.
New Features
------------
MVAPICH2 (MPI-2 over InfiniBand) is an MPI-2 implementation based on
MPICH2. MVAPICH2 0.9.8 is available as a single integrated package (with
MPICH2 1.0.3). This version of MVAPICH2-0.9.8 for OFED has the following
additional features:
- RDMA CM-based connection management support for OFA Gen2 interface
- Support for OFA iWARP: This is for the emerging 10GigE adapters
supporting OFA iWARP interface
- Fault tolerance support
* Checkpoint-restart support for application transparent systems-level
fault tolerance. BLCR-based support using native OFA Gen2 interface
* Flexible interface to work with different files systems. Tested with
ext3 (local disk), NFS and PVFS2
- Efficient Buffer Organization for Memory Scalability of Intra-node
Communication
- Shared memory optimizations for collective communication operations
Main Verification Flows
-----------------------
In order to verify the correctness of MVAPICH2-0.9.8, the following tests
and parameters were run.
