| | 3 | The final test to do was the parallelized test, using differing numbers of front end nodes. I manually launched these jobs, as I haven't organized a proper automatic parallelization over the front end nodes. I also increased the bundle size to 100MB, which does squeeze a bit more speed relative to the 10MB bundles (54.5 MB/s vs 30.5 MB/s at 32 jobs per node). The linear fits are simple eye-ball lines, illustrating that we do not scale perfectly between 1 and 4 nodes. Based on this, we can get gigabit/s speeds using 3 nodes without seriously overtaxing the system with connections. |
