Internet : : We are now in the Top 100 of OGR-27 contest
Posted By: Krashan. on 2013/9/26 7:42:52
After two months of number crunching the Team MorphOS advanced another 100 places up and entered the top 100 of distributed.net OGR-27 contest. Now is the time for the real struggle. Why not to join our 28 members and accelerate the progress? :-)

To take part in the contest one installs distributed.net client - a small program running number crunching in the background. The client is available for lots of platforms, from mainstream down to hobby. Of course MorphOS has its version too. What is important, members of the team can run the client on any of their computers with any operating system. Then, the client downloads its work from distributed.net server (a few kB, so even GPRS connection is enough) and submits the work when done (again a few kB). The goal of the contest is to find the optimal Golomb ruler of size 27, a task, which can be only solved with computing brute force.

    Congratulations!

    Is there any benchmarking on how different MorphOS systems perform?

    Have added dnetc to WBStartup again (until the Mac-Mini fan gets annoying). I've got CoolCow installed, but a dnetc scheduler would probably be more useful: I don't care how loud the fan runs when I'm asleep or at work.

    There is general database on distributed.net site, but I can arrange something on morphos.pl if I will get some data submissions. From my measurements it seems that G4 processors performance is proportional to the clock frequency in a wide range of machines. Have no data for G5.

    I can add a scheduler to CoolCow. For example additional, user definable time period when dnetc is halted and period when dnetc runs fullspeed.

    Are there any MorphOS clients for the medical research crunchers like Folding@Home or the BOINC projects?

    I'll be interested to know how Efika performs aswell.

    Thanks, that would be very useful. :-)

    I've just started the AMD64 dnetc client on my quad core i7 VPS.

    I have to wait now for my name to show up on the stats page before I can join the MorphOS team I think.

    Ok, I've now joined the MorphOS team and also installed the dnetc client on my PowerBook too.

    The VPS runs 24/7 so it should crunch a fair few numbers I guess.

    One thing I noticed when playing around with the client is that 'dnetc -update' behaves as expected on Linux but on MOS once the update has finished it does something nasty to the dnetc executable and stops it from working again.

    It's no problem to just leave it and not run the update manually but thought thought I'd mention it anyhow.

    edit: Actually, even just running dnetc with no options corrupts the executable. I've had to disable the W protection bit for it to work properly.

    edit2: Hmm, it seems that even that doesn't fix the problem. Just running dnetc once and then rebooting is enough for it to corrupt the executable.

    I'm not sure why, any ideas gents?

    Seems very unlikely. Have you checked MD5 sum of the executable file, so you are sure it is really corrupted? BTW MorphOS dnetc client has nice GUI frontend, just start it from icon.

    Code:
    5/0.Work:Applications> lha x Downloads:dnetc-2.9111.520.lha
    5/0.Work:Applications> cd dnetc_mos/

    5/0.Work:Applications/dnetc_mos> md5sum dnetc
    0fe2b76cc42262e52f7736ec17e50474 dnetc

    5/0.Work:Applications/dnetc_mos> dnetc


    Works exactly as expected, so CTRL-C to break:

    Code:
    5/5.Work:Applications/dnetc_mos> dnetc                
    dnetc: file is not executable

    5/10.Work:Applications/dnetc_mos> md5sum dnetc
    b8056c983a03761ccc77b0590f2224b0 dnetc


    Same thing happens when running it from an icon.

    @Intuition:

    0fe2b76cc42262e52f7736ec17e50474 dnetc

    And this is the right hash.

    b8056c983a03761ccc77b0590f2224b0 dnetc

    Unbelieveable... I've checked it several times on my several machines, no such behaviour. The only files dnetc modifies are buffer files (and checkpoint file if one enables it). Maybe you've changed the config, so one of them is called "dnetc"? This may also suggest some general mass storage problem or filesystem corruption.

    Have you tried running it from an SFS partition, see if the behaviour is the same?

    Same thing happens on SFS partition and on RAM:


    It's very strange indeed.
