HP Message-Passing Interface (MPI)
HP Message-Passing Interface (MPI) Version B.11.11 is a
high-performance implementation of the Message-Passing Interface
Standard. HP MPI complies fully with the 1.2 standard and partially
with the 2.0 standard. HP MPI provides an application programming
interface and software libraries to support parallel, message-passing
applications.
New features include:
• Support for the TotalView debugger.
• Support for collecting profiling information for applications linked
with the thread-compliant library in addition to those linked with the
standard MPI library.
• Expanded MPI-2 support.
• A new error checking flag (-ck ) in the mpirun utility.
• The mpirun utility no longer makes assumptions about how long it
will take before a process calls MPI_Init.
HP MPI supports the TotalView debugger on HP-UX version 11.0 or
later.
You can collect profiling information for applications linked with the
thread-compliant library in addition to those linked with the standard
MPI library. Counter instrumentation (MPI_INSTR) is supported for the
thread-compliant library regardless of thread level. Trace file generation
(XMPI) is supported for all thread levels except MPI_THREAD_MULTIPLE.
This release expands MPI-2 support by supporting MPI-2 object naming
routines.
The new error checking flag (-ck) allows you to check appfile set-up,
host machine and program availability, and file permissions without
creating MPI processes.
Timeout errors before MPI_Init that may have been seen in older
versions of the product do not occur in this version because mpirun no
longer makes assumptions about time to MPI_Init.
