A Symposium Highlighting Recent Research
Using the NIH Biowulf Cluster

Tuesday, February 3, 2009
8:30 am - 3:00 pm
Lipsett Amphitheater

In the last decade, the NIH Biowulf cluster has grown from 80 processors to 6500 processors, making it one of the larger general-purpose biomedical computing clusters in the world. NIH intramural researchers have used Biowulf for scientific computation related to genomics, molecular dynamics, image processing, statistical analysis, and other biomedical fields resulting in over 70 papers published in 2008.

The Helix Systems, CIT presents a one-day symposium focusing on recent research that has utilized the computational resources of the NIH Biowulf cluster.
