Are you actually using that computer???

I kept having this problem and now take regular backups of the BOINC folder.

I had a -161 error which manifested at the same time I was viewing a Real Video on the BBC News website.

Someone suggested it might be something to do with graphics card even though I didn\'t have the screensaver graphics running.

I reckon it\'s either that or memory related.....if something hogs the memory or cpu long enough to cause the fatal error.

I suggest you take backups if poss. Suspend the task, exit BOINC and create a backup (I just zip the folder), then restart BOINC and resume the project......2 minutes tops.


Using it \"some\" - the problem is the app won\'t even accually start - it loads, then just sits there.
no cpu time at all.
every other project runs like a racehorse.

hadxxxx5.0x refuses to run - error -161
running fine again on the Op 248\'s and Op 250\'s

any ideas?

BTW - nice charts
Seeing the same thing after a nice recovery in RAC after a big drop. could it be more complex models or "end of phase 3" increased resolution (longer worktimes) ??

What is up with the slow downward slide of the RAC?? I saw this a few times in beta/boinc/seti and thought it was all fixed...

Any ideas???

You describe the long and the short of it willy1. It doesn't matter if it's linux or windoze anymore, the benchmarks are equally bad. "Good enough" as John mentioned was supposed to be a very short-term bugfix, which has now turned into what seems a long term feature. Even true smp benches worse than a single proc mb of equal power. If you "roll your own" boinc_client, you'll gain some on the FP bench, and little or nothing on the INT bench. And yes it DOES have a direct effect on how much credit you claim and have granted, because credit is calculated on time-to-complete vs your benchmark.

FWIW

This has been an ongoing issue with boinc since last year when the benchmarking models changed. some rather powerful cpu's benchmark very badly, especially with HT enabled for both the windows and linux platforms. I resigned myself to the fact that ssl will not address the issue, and has no apparent desire to change it. I have a dual P4 3.06GHz xeon running Linux.latest.smp with HT enabled. The benchmark(s) look like a pIII on a bad day. Solution: Disable HT, reboot, benchmark, reboot, enable HT, and start your model run. As long as you don't change boinc client rev in the process, your machine won't re-bench on restart, so you're good-to-go, so to speak. Also, the self-built boinc_client weighs in at only 5.6mb whereas the "stock client" unzips to something like 8.9 mb as an execuable. You can tweak boinc_client with processor specific optimizations all you want, but it won't make the client apps (hasum etc.) run any faster in the long run. FWIW - YMMV.

The trick is not to let 500,000 people join up on the same day and end up "JQ'd" (old beta joke)
like SSL did - that was a **really big** mistake.

Post:
all my linux boxes have between 512mb and 2gb of regular memory - FC2 installs without a swap file by default..

it's the processor performance I'm complaining about - swap memory does nothing for that. only some optimization of the client to utilize smp/HT will help
