High-performance switches

The IBM product PVMe takes advantage of the IBM SP high performance switch, and can as such be expected to perform somewhat better than the public domain version. Indeed, not until around 28 to 32 processors can a definite decrease in performance be detected. For the 32-processor calculation the speed-up factor was 28.44, which, given our initial aim, we find satisfactory. [Pg.275]
