There are more details on TACC's Ranger
, but some of the highlights worth sharing:
The system occupies six rows of racks in54x38 feet of space, about 2,052 square feet or for those in the US, about half a basketball court
There are 3936 blades in 82 Sun Blade 6048 chassis, each blade with four quad core Opteron processors, for a total of 62,976 CPU cores delivering a peak of over 500 TFlops capacity. The system has completed a full Linpack benchmark, but you will probably have to wait until the next Top500 list to be published in June to find out exactly what the sustained Linpack performance is.
Each blade has 32 GB memory, expandable to 128 GB, for a total of 123 TBytes of main memory
There are 72 x4500 "Thumper" data servers with 1700 TBytes of storage running the Sun Lustre parallel file system.
All compute nodes and storage are directly connected via two Magnum (aka Sun DataCenter Switch 3456) 3456 port InfiniBand switches and approximately 14 kilometers of InfiniBand cable weighting two tons. A traditional IB switch network would have used 300+ switches and six times as many cables.
The Thumper/Lustre architecture is based on the Sun Scalable Storage Cluster solution, which utilizes Sun Fire x4600 data movers which can automatically archive and backup the Lustre file systems using
Sun QFS and
Sun SamFS to multiple StorageTek SL8500 tape silos.
Compute jobs are scheduled on the cluster using the Sun Grid Engine software.
The system is managed using Sun xVM Ops Center
The system uses 2.4 MWatts of power
NSF users have access to the latest Sun Studio optimizing compilers and performance libraries to develop their applications
And if that wasn't enough, right down the street is Rudy's Texas Bar-B-Q.
