Introduction
The timings below were generated on various machines using a simple benchmarking utility in slicer (bench.tcl). The goal was to look at performance scaling for multi-threaded processing.
The machines used were:
- localhost.localdomain: an 8 processor Opteron system with 128 Gig of RAM made available for testing by PC's for Everyone
- mimer.local: a 2 processor G5 PowerMac
- forest: a 10 processor SunFire
- vision: a 6 processor Sun
- rock: a 3.4 gigahertz pentium 4 dell XPS laptop (one processor - two thread timings use 'hyper threading')
- deuce: a dual processor opteron
- glider: a dual processor xeon (with hyperthreading to get 4 threads)
Times in the boxes are in seconds.
Results generated with blur.tcl. Gaussian smoothing with local memory access.
