Recently, two my colleagues (Grzegorz Kokosinski and Krzysztof Zarzycki) were at GTC 2012 (GPU Technology Conference) in San Jose, California.

Problem definition: given a reference sequence, how to find the one most similar to it among a large database? The sequences are millions characters long, and their similarity is calculated with a (quadratic) DP algorithm,... [More]
