Cray systems specifications and queues

Due to the many Cray systems now on the SCD computer room floor (eight of 'em), this brief specifications chart is often useful to me. You might find it helpful when preparing your jobs. The first four systems are the community computing machines, and the second four power the Accelerated Computing Environment (ACE).

*  antero can do *all* HPM (high Performance Monitor groups simultaneously.
** antero has *2* sets of vector registers, so peak MFLOPS is 2*480.

For additional information about each Cray computer, try the 'CRAYINFO' command. This tells you about the batch job queues, your interactive limits, disk quotas, etc.

Cray job queues

For the convenience of Cray users who might be submitting batch jobs to more than one Cray, here is a short summary of which job queues are allowed on the various Cray systems.
