Impact of concurrency on the performance of a whole exome sequencing pipeline

摘要

Speedup comparison. Expected speedup for CES compared to the NPS for 2 and 3 samples as a function of the available number of processors and PaCo proportion γ. The magenta dashed line represents the measured speedup of the real pipeline tested. The green dashed-dotted line represents the expected performance gain based on the estimated proportion of sequential execution time of our pipeline. In the 2-samples figure there are three observed speedups associated to all the combinations of two samples out of the three available. In the 3-samples figure there is a single observed speedup associated as there is only one possibile triplet out of the three available samples
