Following several requests we have decided to extend submission deadline for PBC 2007 (http://pbc.pcz.pl). All papers should be submitted before May 9, 2007 (23:59 CEST). The goal of the PBC Workshop is to present the latest research in high-performance computing applied to bioinformatics. We are especially interested in parallel and distributed algorithms, memory efficient algorithms, and design of high-performance software for clusters, massively parallel systems and grids. Papers presented during Workshop will be included into the proceedings of the PPAM Conference (http://ppam.pcz.pl) and published after the conference by Springer-Verlag in the LNCS series. * Submission of Papers: Sunday, May 9, 2007 (23:59 CET) * Notification of Acceptance: Friday, June 15, 2007 * Conference: September 9-12, 2007 * Camera-Ready Papers: October 15, 2007 For more information please visit http://pbc.pcz.pl Regards, Jaroslaw Zola
