This is describing a demo that combines Lane15 Infiniband, AMD Opterons

I don't know what will be announced, but there is obviously a bunch of
work in this area.

The systems are usable today, with most support and applications running
in 32 bit.  Our 28Cz-5 release, first showing this evening, and the
28Dz-5 Demo Zero Install Cluster, introduced Tuesday, are 32 bit
releases that have Opteron tweaks and testing.  The x86-64 release date
has not yet been decided.

I'm not certain if we will be running a 32 or 64 bit kernel on Opterons
at SC2002, but the applications we are running on the systems are all
still in 32 bit mode.  That will change when the SC2002 pressure is

The system software is almost ready

We've had an Alpha AXP distribution out for ages, but...
