HP-MPI Version 2.2.7 for Linux Release Note

1 Information About This Release
1.1 Announcement
This release note describes the release of HP-MPI Version 2.2.7 for Linux.
Version 2.2.7 is the April 2008 release of HP-MPI, the HP fully functional implementation of the
Message Passing Interface standard for Linux. Version 2.2.7 for Linux is supported on HP ProLiant
and HP Integrity servers running Red Hat Enterprise Linux AS 4 and 5, or SuSE Linux Enterprise
Server 9 and 10 operating systems, as well as 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 complies fully with the MPI-2 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, whenever appropriate, to provide low latency and high bandwidth
point-to-point and collective communication routines. HP-MPI supports multi-protocol execution
of MPI applications on clusters of shared-memory servers so that applications can take advantage
of the shared memory for intra-node communications.
HP-MPI supports multiple interconnects and enables the customer to build a single executable
that transparently takes advantage of the supported high performance interconnects. This greatly
reduces the efforts of customers and Independent Software Vendors (ISVs) to make their
applications available on the newest interconnect technologies.
HP-MPI is available as both archive and shared libraries. HP recommends the use of shared
libraries. To use shared libraries, HP-MPI must be installed on all machines in the same directory
or accessible through a shared file system.
NOTE: The option to link archive versions of HP-MPI libraries is being deprecated and will be
removed from a future release of HP-MPI.
