Greetings SP User,

A four day outage has been scheduled for seaborg on Oct 11 - Oct 14. The
system will be upgraded from AIX 4.3 to AIX 5.1 and many other software
levels will also be upgraded.

AIX 5.1
Parallel Environment 3.2
IBM C/C++ 6.0
IBM Fortran 8.1

With a few exceptions existing executables will run as before. Major 
changes include:

* 64 bit MPI is now supported (was beta software).
* Existing 64 bit binaries must be recompiled, 32 bit
   codes should run without modification.
* New compiler features, including:
     Fortran support for OpenMP v2.0
     C++  support for OpenMP v1.0 and MPI Bindings

We will keep you posted at

David Skinner
