Saw this demo while at SC06 today - this is great news for folks looking to use HPC clusters.

The Open Grid Forum (OGF) announced its interoperability demonstration at the Supercomputing 2006 (SC06) conference showing the work being done towards interoperable high performance computing (HPC). Organizations participating in the demonstration include Altair Engineering, CROWN, EGEE, Fujitsu Labs of Europe, Genesis II, Globus Alliance, HP, Microsoft, OMII-UK, Platform Computing, Tokyo Institute of Technology, and University of Virginia. These participants are exhibiting their prototype implementations of OGF standards and draft specifications used to enable heterogeneous integration of HPC Grid solutions.
The demonstration involves compute clusters processing various HPC applications submitted via OGF's Open Grid Services Architecture (OGSATM) HPC Profile draft specification, which leverages common Web Services specifications and existing OGF standards. The use of widely adopted Web Services and OGF specifications enables the interoperable interaction between different HPC middleware platforms.
