We have just released an accelerated implementation of profile HMM software for protein sequence analysis. It runs on CLC Bioinformatics Cell, which uses SIMD technology to unleash already existing powers in your computer processor. Searches previously taking more than 3 hours can be done in less than 10 minutes!
100 random sequences from Swiss-Prot were compared to the whole Pfam database. Both the fs and the ls versions of Pfam were used.
| Version | Time | MCUPS | Speedup factor |
| Original | 1:19:23 | 32,5 | 1 x |
| Cell | 0:03:26 | 749,6 | 23,1 x |
Ten random models from Pfam were compared to the whole of Swiss-Prot. Both fs and ls versions of the models were used.
| Version | Time | MCUPS | Speedup factor |
| Original | 1:33:23 | 57,1 | 1 x |
| Cell | 0:03:45 | 1420,3 | 24,9 x |
Computer: 2.13 GHz Intel Core 2 Duo with 2 GB RAM running Fedora Core 6.
| Database | HMMs/Sequences | Positions |
| Swiss-Prot 53.3 | 274295 | 100696439 |
| 100 proteins from Swiss-Prot | 100 | 40993 |
| Pfam 21.0 fs + ls | 17914 | 3772912 |
| 10 models from Pfam fs + ls | 20 | 3176 |
Notes
All programs were run with default parameters. Binary versions of the HMM files were used for hmmpfam.
