    Abstract

    A striking example of the effectiveness of High Performance Computing was recently demonstrated on an IBM POWER4 platform. The project involved a biological application called "Independently Consistent Expression Discriminator (ICED)." ICED is a sample classification application for microarray data analysis that helps identify disease-relevant genes for medical research. After enabling and tuning ICED on an IBM eServer pSeries 690, a job that used to take more than three days on Microsoft Windows now takes about 10 minutes on AIX.
