FWIW, I'll be at SC09 next week, mostly on INRIA Booth #1405. I'll present hwloc (among other software we develop here).
I'll have a USB key with lstopo static binaries (from the libpci branch) so that people can run it on their machine immediately. I hope somebody will show up with a 192-core laptop, otherwise the lstopo output will often be very simple :) Brice
