Docking performance accelerated 30-50 fold on the Cell/BE processor

Abstract:
The eHiTS flexible docking has proven to be among the most accurate pose prediction tools (http://www.simbiosys.com/ehits/ehits_validation.html) providing one of the highest enrichment factors based on comparative evaluation studies (http://www.simbiosys.com/ehits/ehits_enrichment.html).
The accurate results of eHiTS have been achieved at the price of longer
CPU times in the past, but that has changed with the recent port of the
algorithm to the Cell/BE processor (http://www.bio-itworld.com/issues/2008/july-august/simbiosys.html).
The revolutionary hardware that powers RoadRunner (the world's current
fastest supercomputer) and also available in the low cost SONY PS3 game
console, gives eHiTS 30-50 fold speedup compared to a single core
Intel/AMD processor. The advantages of the Cell/BE platform over other
acceleration techniques (FPGA,GPGPU) will be described, along with the
challenges faced during the porting effort. A new proximity data
structure is introduced that is optimized for SIMD architectures. It
allows efficient evaluation of short range pairwise interactions with
optimum cache locality.
