We accelerated the OpenCL backend of pyPaSWAS sequence aligner




Last year we accelerated the OpenCL-code in PaSWAS, which is open source software to do DNA/RNA/protein sequence alignment and trimming. It has users world-wide in universities, research groups and industry.

Below you'll find the benchmark results of our acceleration work. You can also test out yourself, as the code is public 1. In the readme-file you can learn more about the idea of the software. Lots of background information is described in these two papers:

We chose PaSWAS because we really like bio-informatics and computational chemistry - the science is interesting, the problems are complex and the potential GPU-speedup is real. Other examples of such software we worked on are GROMACS 4 and TeraChem 5.

The efforts Stream HPC put into accelerating pyPaSWAS are very much appreciated. The speed-up has a direct effect on our ability to run even larger data sets. Also, Stream HPC shows that having computer science engineers on board life science projects is of great importance.

Benchmarks

A number of different datasets were used for the query and database. The comparison is between the performance of the original code and our branch. The scoring matrix used is BLOSUM80, with all other parameters set to default. NOTE: The results below are for the non-affine gap method.

An example of how a benchmark is run, is: time python pypaswas.py --loglevel=info -M BLOSUM80 data/canisLupusAnkyrinPRED.fasta ../canisLupusFamiliaris.faa_4284.faa --device_type=GPU --platform_name=AMD --framework=OpenCL --device=1

You can change the variables as we put in the dataset description.
