    Now that we have this wonderful new Linux 4.81 client (thanks guys!), what is the general opinion about running it on an optimised BIONC core program?

    If this was Seti@home I would just go for it, but the quality of the science is far more important here, so that is why I am asking for an opinion.

    Is it worth going for the 20% to 30% improvement in benchmark figures? Will it make a difference at the end of the day? Most importantly, will it affect the quality of the science?

    I have been getting results between 27,425.21 seconds and 28,510.32 seconds with the new Einstein 4.81 client on the standard 4.43 BOINC client.

    As we all know the BOINC core client is responsible for the benchmarking, which affects credit awarded, and I have been getting miserable benchmark scores under Linux :(

    Here are my Linux and WindowsXP benchmarks:
    Slackware Linux (std 2.6.12.3 kernel), BOINC 4.43:
    Measured floating point speed 986.5 million ops/sec
    Measured integer speed 1913.33 million ops/sec

    WinXP SP2, BOINC 4.44:
    Measured floating point speed 1875.86 million ops/sec
    Measured integer speed 3126.59 million ops/sec

    The computer is a dual-boot system, so everything should be effectively identical, other than me still having to recompile the Linux kernel to recognise my full 1Gig of Ram.

    I have checked the Wiki and it seems non-commited on this issue. The Seti forums are so full of moaning and hot air that it is hard to find any useful information at the moment :(

    PS No offence intended by the SETI comments :)

      The BOINC Core Client version doesn't affect the results at all, they are solely done by the Applications.

      The Client might have a minor impact on the crunching time (depending on how much CPU time it takes for itself and the priority setting it starts the App with), and of course on the benchmark results, thus on the credit claimed. A buggy client may cause more "client errors", but that's about it.

        Thanks very much :) Thats what I hoped but I wanted an expert opinion.

          Which optimized BOINC core client for Linux are you using and where did you get it?

            I'm not using one yet but there are 2 I was thinking of, Ned Slider and Cris Brosshard's 4.19 BOINC client here
            or perhaps the 4.44 here by Metod.

            Metod's are optimised for Intel and Ned's are mostly for AMD but Metod has a 4.44 client.

            I'll probably end up sticking with the vanilla BOINC :)

            PS: Here is the links page to unofficial clients at the BOINC site.

            Edit : linked and corrected hyperlinks
