The frequency is 50 to 60 Hz. Each processor in a node has its own separate L 1 and L 2 caches, with the L 2 cache configurable from 1 to 4 MB with a cache block size of 128 bytes and 2-way set associativity. More benchmarks and performance measurements on the Origin2000. 128 CPU CRAY Origin 2000 using 250 MHz R10000 MIPS processors and 32 GB Distributed Shared Memory. 6.5SE Operating System.
All timings presented here are in seconds of wall clock time as reported by the application.
These times include all program initialization and termination in addition to the time spent in the actual computation. For more on these tests, see Faulkner's work . Performance of Fortran 90 Array Intrinsic Functions on the SGI Origin2000 at Scientific Computing and Visualization lab of Boston Univ. The Advanced Architecture Performance Evaluation group at LANL did an interesting performance study of the Origin2000, a copy can be found here . NCSA keeps a suite of Performance Highlights for Computational Community .
