The next phase of PSC's XT3 "Red Storm" system has been installed in PSC's WEC machine room. This brings the total installed XT3 capability to approximately 5 Tf. Application work, featured on a "live" XT3 in the PSC booth at SC04, continues on the expanded system. Further expansion is expected in the near future. This is the first installation of Cray's XT3 product anywhere.
