Building a Bioinformatics Supercomputing Cluster
Our local cluster is able to search an up-to-date database with fewer concurrent users and better overall throughput times than is the NCBI Web site. Simple wall-clock time trials were performed using our cluster and the NCBI Web site. We used eight simple queries consisting of protein and DNA sequences. A timer was started after submitting a query from the Web site and stopped once the results were displayed in the browser window. Trials on the NCBI Web site were performed at various times throughout the span of two weeks. All eight trials were averaged and compared to the cluster's times. The purpose of timing the query from the point of submission until the results are displayed was to observe times that an actual user would incur. On average, the cluster took less time to complete a query.
