    I'm at this moment crunching a WU, so I thought I'd take a look to see if the other half of the Quorum had already been completed. To my surprise, it has been, by some super-cooled mega computer, because E@H says it was done in 0.00 CPU seconds... see for yourselves : http://einsteinathome.org/workunit/37025972

      If you take a look at the full tasks list for that computer, the large majority of tasks are taking around 30K seconds. For some reason, occasionally, a result will be reported with no elapsed cpu time. There is obviously a software glitch - perhaps in an OS library, or in BOINC's interaction with the OS - which is not allowing the proper calculation of cpu time. There is nothing wrong however with the science app output since the results are correctly validating and the correct credit is being recorded.

      The Windows 9x OS has a habit of doing things like this. There is nothing to be concerned about.

      Cheers,
      Gary.

        Thanks Gary.. I thought it must be something of the sort, but it's the first time I've seen such a WU, so I thought I'd better report it!! :)

          Not only W9x. His OS 2.6.20-gentoo-r8 is also known for that.
          Nice to see that Gentoo don't ever produce crunching errors like Bikeman wrotes in an other thread.
