High Performance Computing


       I am the manager of High Performance Computing @ UMASS Medical School
I work with the researchers here at UMASS on computational elements of HPC.  I am currently working on HG matching and the setting up of LIMS systems.  We currently are in the process of completing an upgrade to our clustered environment.  Our clustered environment will be upgraded and will have over 1400CPU’s between all the clusters running CentOS and SGE.
