Execution time of the alignment of sets of ten randomly-generated sequences of different sizes, using Clustal W implementations.

<p>The tested algorithms are the original Clustal W 1.83, the MC64-ClustalWP2 for Tile64 and PC, and two parallel implementations for x86 systems (MT-ClustalW and ClustalW-MPI). In addition, the minimum gain ratio of the MC64-ClustalWP2 against all the other implementations is exposed for each set of sequences.
