    Find it on the revived Power User Apps page.

    This was built "hands-off" on YellowDog Linux on a Sony PS3 and thus should run under similar installations.

    In contrast to the BOINC Core Client of PS3Grid this is an unmodified one. In particular it doesn't hardcode the CPU number to 1, so without further settings ("on multiprocessor systems use only 1 cpus") this Core Client won't work with the PS3Grid Apps.

    The Einstein@Home App doesn't make use of the SPEs (yet), so isn't very fast compared to what other projects get out of the Cell CPU. On the other hand it should run on other non-Cell Linux/PPC systems, too.

    I'd be curious to know how running this App in two threads ("2 CPUs", per default) compares to one thread (limit to 1 CPU or use PS3Grid Client) on the Cell, and whether there are other installations it runs on, too.

        Sorry, I don't understand - are you running Linux on your G5 Mac or MacOS X?

          So, maybe i lust change something!

          The BOINC version used in this App probably still has the "lost heartbeat crash" bug we've seen a lot with Linux Apps e.g. 4.20. Try to get or compile a BOINC Core Client that doesn't hang e.g. on network problems.

          I intend to update the Linux/PPC App soon, which should fix the bug on the App side. I don't know when, though.
