22) Message boards : Number crunching : Problems with Rosetta version 5.64 (Message 41116) Posted 18 May 2007 by Neil Post: I am experiencing reboot about 3x/day with Rosetta 5.64 on my SuSE Linux 10.1 AMD Athlon 3800+ system. This reboot behavior stops when I suspend Rosetta. Was Rosetta ever running successfully on this Athlon 8300+ and then it recently developed this problem? or is this a new Rosetta client that's having trouble getting off the ground? Any ideas why? I'm just a beginner, but: 1. Hot microprocessor? You can reduce the load on your CPU in your General Preferences > Processor Usage > Use at most XX percent of CPU time Enforced by version 5.6 and greater 2. Linux-Boinc having trouble with Rosie 5.64? Maybe install WinXP onto your Linux computer, using an installation disk from one of your other machines. You should have a month before the Activation/Verification thingy kicks in to see if XP helps the spontaneous restart problem. 3. You might try downloading a copy of memt86, which exercises RAM. Let it run for a day especially during warmer ambient temperatures to see if errors are detected. Google for "spontaneous reboot." http://ask.metafilter.com/52269/XP-spontaneous-reboot-related-to-full-folders "... If the machine is "spontaneously rebooting," are you getting any event error log codes or blue screen errors, or stop log (memory dump) error codes? If so, investigating these could pinpoint your problem. In my experience, 99% of crashes resulting in "spontaneous reboots" turn out to be memory related..." He certainly sounds like he knows what he's talking about.

And even if it did, Rosetta does not have the capability to checkpoint at a forced point in time. It reaches predefined points in the model's computation and those are the only points where it can do a checkpoint. I was slow to reply because your meaning was slow to sink into my dense cranium. However, you couldn't say it any clearer. Checkpoints can only be created at predefined points in the model's computation. And it sounds like Rosetta is already taking advantage of most of those predefined points. OK, how about this for a compromise: How about adding an audible alert whenever Rosetta "does a checkpoint" or starts a new WU? If my WinXP starts to run hairy and if I'm able to wait until Boinc beeps, then I could take the opportunity to restart Windows without losing hardly any work. Of course, the beep should be user-selectable with an On/Off switch. I would only switch the alert On when my computer starts getting an anxious aura, and it should conveniently automatically reset to Off after Boinc restarts. Then, I would be one with my Boinc.

From the longest to shortest interval between checkpoints: 1. 2. 3. and, a more recent addition, checkpointing for pose and jumping jobs. These types of jobs should checkpoint at intervals depending on your disk write interval preference. I have an old Celeron 1.4 GHz with massive 256 kB L2 cache and Boinc 5.8.16. My antivirus wanted me to do a re-start, an infrequent request. I checked Rosetta, and my 5.64 WU was at 1:50 CPU Time, and 1:05 To Completion. After restarting, the work unit reverted to 1:20 CPU Time and 1:35 To Completion. I think it would preserve lots of work (especially on my general-use computer) if Checkpoints were also saved when Boinc is manually exited. Do we have the technology? ---- Query: Regarding "posing" and "jumping jobs," what is posing? I searched a few days ago and couldn't find a definition. I don’t sup-pose it has to do with manually exiting Boinc? Thanks. Neil
