2-Thunder takes Apple machines to a very high supercomputing grade.
Thunder, I think runs on a 1000+ Apple machine cluster.
No, that's the 'Big Mac' machine at VPI built by Srinidhi Varadarajan,
which was no.6 on the TOP500, but didn't make it this time because
it has been taken apart for rebuilding. It originally used Apple
servers with dual G4s in a tower case, but they're being replaced
by Apple XServe 1U dual-G4s.
Thunder is based on Intel Itanium2 (Madison) nodes (probably dual
or quad CPU, I'm not sure) and Quadrics interconnect. A planned CPU
upgrade next year will replace the Madison CPUs with dual-core
Montecito CPUs, almost doubling the peak performance without any other
change. It may get to No.1 with this upgrade.
Thanks for the correction. I missed that while reading

The super-computer I built was for Lawrence Livermore National Labs
). It has 4096 Itanium2 64 bit Processors, 8TB of
RAM, Quadrics Interconnect and runs GNU/Linux. Code named "Thunder",
with a performance of 20 trillion floating point operations per second
will rank second place on the next TOP500 list of the worlds most
powerful supercomputers. All the software I wrote for Thunder is
released under GNU GPL.
With accessible hardware, broadband and free software, supercomputing
may reach many more easily. HTH.
