  1. The fourthcorner analysis is performed on the Bacillus anthracis example dataset on 1 and 10 cores for different numbers of permutations as indicated in the first row. The following rows indicate the required user time in seconds while the last row indicates the relative speed-up of the multi-threading approach. The run time was profiled on a server with 72 Cores (Intel Xeon CPU E5-2699 v3 @ 2.30 GHz) with 512 GB RAM
