Figure 2. Processing time per CCLE sample using the cluster-based configuration.

The 934 CCLE samples were processed on a cluster of 295 virtual machines. The horizontal lines represent the relative start and stop times at which each sample was processed. Darker lines identify samples that took longer to process. The longest-running sample took over 4.5 hours to process; the shortest-running sample completed in less than 1 hour. All but two samples finished processing within 7.5 hours. These two samples failed due to a disk-mounting error, so we reprocessed the samples on a smaller cluster (see Methods).
