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 which are further described below 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.
