HP-MPI V2.3 for Linux Release Note

1 Information About This Release
1.1 Announcement
HP-MPI V2.3 for Linux is the November 2008 release of HP-MPI, the HP implementation
of the Message Passing Interface standard for Linux. V2.3 for Linux is supported on
HP ProLiant and HP Integrity servers running Red Hat Enterprise Linux AS 4 and 5,
SuSE Linux Enterprise Server 9 and 10 operating systems, and HP XC3000, HP XC4000,
and HP XC6000 Clusters.
1.2 What’s in This Version
HP-MPI is a high-performance and production-quality implementation of the Message
Passing Interface standard for HP systems. HP-MPI fully complies with the MPI-2.1
standard. HP-MPI provides an application programming interface and software libraries
to support parallel, message-passing applications that are efficient, portable, and flexible.
HP-MPI uses enhancements to provide low latency and high bandwidth point-to-point
and collective communication routines. On clusters of shared-memory servers, HP-MPI
supports the use of shared memory for intranode communication while internode
communication uses a high speed interconnect.
HP-MPI supports a variety of high speed interconnects and enables you to build a
single executable that transparently uses the supported high-performance interconnects.
This greatly reduces efforts to make applications available on the newest interconnect
technologies.
HP-MPI is available as shared libraries. To use shared libraries, HP-MPI must be
installed on all machines in the same directory or accessible through the same shared
network path.
NOTE: HP-MPI V2.3 only provides shared libraries, and only supports execution of
executables linked against shared MPI libraries. Older executables linked against archive
libraries either need to be relinked with HP-MPI V2.3, or run under HP-MPI V2.2.7 or
earlier.
1.2.1 Platforms Supported
HP-MPI V2.3 is supported on the following systems.
