HP-MPI Version 1.2 for Windows Release Note

1 HP-MPI V1.2 for Windows Release Note
1.1 Announcement
This release note describes the release of HP-MPI Version 1.2 for Windows®.
HP-MPI V1.2 is the November 2008 release of HP-MPI, the HP fully functional implementation
of the Message Passing Interface standard for Windows. HP-MPI V1.2 for Windows is supported
on servers and workstations running Windows HPC Server 2008 (HPCS).
1.2 What’s in This Version
HP-MPI is a high-performance implementation of the Message Passing Interface standard.
HP-MPI complies fully with the MPI-1.2 standard and provides MPI-2 one-sided functionality.
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 shared libraries. Therefore, HP-MPI must be installed on all machines in the same
directory or be accessible through a shared file system.
NOTE: The default directory location for HP-MPI for Windows 64-bit is
C:\Program Files (x86)\Hewlett-Packard\HP-MPI
1.2.1 Platforms Supported
HP-MPI V1.2 for Windows is supported on the following hardware running HPCS. An active
directory domain is required to run HP-MPI.
• HP Cluster Platform 3000 and 4000
• HP ProLiant BL20p, BL25p, BL30p, BL35p, DL140, DL145, DL360, DL380, DL385, DL460C,
DL480C, and DL585
NOTE: HP-MPI strives to be compiler neutral. HP-MPI V1.2 for Windows systems was tested
with the Intel® Fortran 10.1 and Visual Studio 2008 compilers. In addition, other compilers can
be used if the Fortran calling convention is C by reference. HP-MPI does not support the Compaq
Visual Fortran (CVF) default calling convention.
1.2.2 Directory Structure
All HP-MPI for Windows files are stored in the directory specified at installation (default: C:\
Program Files (x86)\Hewlett-Packard\HP-MPI). The directory structure is organized
as described in Table 1-1.
If you choose to move the HP-MPI installation directory from its default location, set the
MPI_ROOT environment variable to point to the new location.
