1) Message boards : Number crunching : What happend on July 5th ? (Message 21209) Posted 26 Jul 2006 by mahdia Post: Grettings from Berlin ! As you look at the user charts at the rosetta homepage there is a significant increase near the 5th of July . What happend on that day (or the days before) ? I looked through the project news and the forums, but found nothing special action undertaken from the project team to attract such a lot of new users. Regards, mahdia
2) Message boards : Number crunching : can it really be so slow ? (Message 687) Posted 28 Sep 2005 by mahdia Post: Hello ! Today morning when I came into my office, another workunit on the fast P4 was stucked at 1% since 5 hours. After a restart of the whole boinc service all works fine and the particular WU is at 16,67 % right now. It seems, that there is a bug in the rosetta application, which causes under circumstances the application to be stucked. Looks like an invalid ending condition of a loop or so (this is only a assumption). Regards, mahdia

(Message 616) Posted 27 Sep 2005 by mahdia Post: If you are running multiple projects on that computer, you may also need to extend the time between project switching from 60 minutes to 120-180 minutes. Otherwise it will never reach the next checkpoint before switches and will always revert back to the last checkpoint. But doesn't that matter when applications are stay in memory while preempted ? As an additional, I had one work unit get stuck at at 1%. A simple restart of BOINC fixed it, and the work unit finished fine. This is an option, if you can watch the computer in regular intervals. But all my BOINCing hosts are on 7/24 and BOINC runs in service mode with no one is logged on .

It tends to move in jumps. It often appears "stuck" at certain percentages, 83.3% for example is a regular "sticking point". It is not in fact stuck, it suddenly lurches forward after a stage has been completed. I know this well. But stucking on 1% for over 10 hours is not normal. It seems to be a problem with this particular workunit. The next one I started 5 minutes ago reached 8.33 % just this moment. Seems to work well. I wonder if the workunits should behave so different? Perhaps they do ohter sort of computation, but I don't think so. Perhaps there was a drunken bit in ;-)

(Message 611) Posted 27 Sep 2005 by mahdia Post: [/quote] Right, too slow specially when i read "but the good old P3 seems to stuck on 1% since 10 hours" Can you suspend this wu (not abort) and begin a new wu ? [/quote] Suspended, let's look, how the next one will do the job.

7) Message boards : Number crunching : can it really be so slow ? (Message 603) Posted 27 Sep 2005 by mahdia Post: Hello. I added this interesting project (one of three current protein projects, I think) to two of my computers. One of these two is a P3 1 GHz, the other a P4 3 GHz HT. On the last one all works fine, but the good old P3 seems to stuck on 1% since 10 hours. The displayed speed is ca. 5 MFlOPs, which is realy slow. The same computer reaches over 600 MFlOPs with Einstein@home, so I wonder, why the rosetta application is so slow ?
