    Do they have a new Supercomputer?

    They have a real skyrocket statistic and most of the work is done by Erik A. Espinoza, so he must have a lot of CPU's (~400).

      I think it's the new LDAS cluster (LIGO Data Analysis System) there that now runs E@H as a backfeed job, i.e. if the nodes are doing nothing else. IIRC it has about 1200 Opteron cores.

          It will be interesting to see if they come close to beating Bruce Allen one day ;-)

            Doesn't the Nemo cluster have 1280 cores? It's gonna be a close race ;)

                  I think the Caltech cluster is slighly more powerful than Nemo, but apparently more busy with other jobs right now. Might become a close race.

                  Well Nemo had a head start...

                    Well Nemo had a head start... so I guess they will come out first in the end.

                      We are getting another 140 nodes for our cluster (280 cores). So we'll be up to 1560 cores in another month or so. You can track the usage of all the LSC computing clusters at this Ganglia site.

                      By the way, we are about to start using Nemo for doing some of the post-processing analysis from the Einstein@Home S4 run that finished early this summer. In general I expect that as the S5 run progreses, these LSC computing clusters will be more and more heavily used for other types of analysis, and their Einstein@Home 'bottom feeder' contributions will shrink.

                        Just out of interest: Do you have a rough estimate how long the S4 postprocessing will take?
