A component-based implementation of multiple sequence alignment

This paper addresses the efficient execution of a Multiple Sequence Alignment (MSA) method, in particular the progressive alignment-based CLUSTAL W algorithm, on a cluster of workstations. We describe a scalable component-based implementation of CLUSTAL W program targeting distributed memory machines and multiple query workloads. We look at the effect of data caching on the performance of the data server. We present a distributed, persistent cache approach for caching intermediate results for reuse in subsequent or concurrent queries. Our initial results show that the cache-enabled CLUSTAL W program scales well on a cluster of workstations.
