• IMPI functionality. The Interoperable MPI protocol (IMPI) extends the power of MPI
by allowing applications to run on heterogeneous clusters of machines with various
architectures and operating systems, while allowing the program to use a different
implementation of MPI on each machine.
• Fortran profiling interface. To facilitate improved Fortran performance, we no longer
implement Fortran calls as wrappers to C calls. Consequently, profiling routines
built for C calls will no longer cause the corresponding Fortran calls to be wrapped
automatically. In order to profile Fortran routines, separate wrappers need to be
written for the Fortran calls.
• Expanded support for collecting profiling information. 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.
• A new error checking flag (-ck) in the mpirun utility. 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.
• The mpirun utility no longer makes assumptions about how long it will take before a
process calls MPI_Init. 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.

HP Visualize Conference
HP Visualize Conference is a collaborative conferencing solution for HP Workstations
that can interoperate with Microsoft’s NetMeeting, Sun’s SunForum, and SGI’s
SGImeeting products.
Functionality changes have not occurred in HP Visualize Conference since version 1.3
was released. Version 1.3 added support for NetMeeting 3 while maintaining backward
compatibility to version 1.2 and NetMeeting 2 via two running modes:
