The content test was done on all four architectures, yielding similar results on each architecture. One sequence (13955) took significantly more time than the others in the BLASTP test, and another sequence (14133) took less time than the others in the BLASTX test. However, for BLASTN, the run time was fairly consistent for all five sequences. The Cray CS6400 search times are shown in Table , with the neighborhood word list sizes and number of database word hits for each sequence.

The results of the sequence length test for the SGI Challenge are plotted in Figure . The results for other architectures are similar. The confidence intervals are plotted in the figure.
Figure: Length test on SGI Challenge: Doubling the length of the sequence doubles the run time.
