“The ATLAS cluster, linpack measured 32.8 TFlops and a
theoretical peak of about 50 TFlops, consists of 1342 Supermicro
computer nodes (Intel Xeon 3220 quad-cores 2,4 GHz, 8 GB RAM, 500
GB Hitachi HDD, IPMI remote management) along with 31 data servers
(2x Intel Xeon E5345 2,33 GHz, 16 GB RAM, Areca 1261ML, 16×750 GB
Hitachi HDD) plus 4 similar head nodes with 4 x 750 GB HDD. Those
are all running Debian GNU / Linux 4.0 Etch with a few
modifications like custom kernel and Condor queuing system.
Additional storage space is supplied by 13 Sun Fire X4500 running
Solaris 10. The system was built from off-the-shelf computers from
a German company, Pyramid Computer GmbH.”
