Outside of the active_frac it looks normal. I have heard of this problem on other projects, one fix was to do a project reset. That will wipe out any active WUs, but will reset all vars and start clean.

Interesting you mention "reset" rather than attach/detach. I did R & R the BOINC MGR, but didn't try a reset.


Rather than kill the current WUs, you could set "no new tasks" and let the queue run out, then do the reset.

Absolutely! There's too much at stake here for all involved, and I expect the same consideration from my fellow wingmen. I am a little teed off though, that on one of my attempts at modifying the active_frac file I got a download error. Haven't had any errors since the faulty WUs of several months back, so I suspect my fiddling around had something to do with it.

Thanks for your suggestions.

<edit

I take that back: Seems 638479 has errored out on 3 other peeps w/i minutes of mine.

Here ya' go Mike:

Q6600 Stress Test @ 3.6 Running

Q6600 Stress Test @ 3.6 Stopped

This was an >14 hr stress test done just a week or two ago. The initial validation period was approx 24 hrs Quad Prime95, 8 hrs Memtest86+, and 2 or 3 hours looping 3DMark2001, before initial deployment. I then re-validate (varying time frames) every few months. All machines are on APC UPSs with USB enabled s/w shutdown.

Trust me, I'm glad you're concerned about stability. I'm somewhat of a stability freak myself. To be any less, especially on a alpha or beta project, is unconscionably irresponsible, IMHO.

Thanks for bringing it up, tho.

Nah -

Just tried again, with BOINC fully exited. I could launch BOINC while suspended, and the active_frac file was at the 0.99 value I entered. As soon as I took the project off suspend, it reverted back to the low value.

Is it 1679 that is the problem? It looks like you are over-clocking the snot out of it. My Q6600 (running @2.8 GHz) benchmarks at 2700, yours is 3600 or so. That may or may not be part of the issue, but I am worried when I see an average turn-around time or 0.07 (just over an hour).
Are you stopping Boinc (including the service, if running as a service) before doing the edit on client_state.xml? You can't change anything while boinc is active.

Good estimate - 3.6 she is, under water. I validate all my machines for a minimum of 12 - 24 hrs under Prime for all cores. I did this machine for >14 hrs using Quad Prime just recently. She's run thousands of DC WUs, including months of C@H over the past year or so, w/o any error issues, and I just re-validated her a few weeks ago. I'll see if I can host a screenie of the stress test completion, but I'm very confident of stability.

I did the HTML editing several times, including with BOINC exited. I do admit I'm no HTML pro, tho. I'm considering another R & R of the BOINC MGR, but this time checking if the BOINC folder is removed. IIRC, the BOINC diredctory remains after an uninstall....well it worked that way a while ago, not sure if it still does.

Hi guys -

Sorry to have yet another issue after yesterday's minor attachment SNAFU, but this has been an ongoing problem for many months, and is irritating the heck out me.

In my client_state file the active_frac value is ridiculously low; something on the order of 0.00048! This has been keeping me from getting more than one WU per core on this specific machine (my other machines are fine), and also forcing one or two of the four WUs to always be running in "high priority" mode (the machine is a Q6600 C2Q). I have no idea how this came about.

To make matters more difficult, I've even manually edited the active_frac value using an HTML text editor, only to have it always revert back to the same extremely low value whenever the BOINC MGR contacts the project (including on initial start-up)! I'm trying to ascertain if the state reverts only during comm or if during other actions of the BOINC MGR, but I'm not fully knowledgeable on when comm is taking place in the normal launching and running cycles of the BOINC MGR.

Is the active_frac value set by the project server upon comm? Or possibly in some (XP) registry key (I checked and didn't see it in the usual BOINC reg keys)?

The only BOINC project currently running on this machine is C@H. To add further insult, I even removed and re-installed the BOINC MGR, to no avail.

I'm really at a loss on this one.

If this issue is beyond the scope of the C@H project forum, I'll head over to the BOINC forums. I hate to bother you guys with something "generic" BOINC if you believe this doesn't fall under the realm of C@H.

Thanks.

Eddie

Let's close this "ticket"! ;-)

I just got a successful attach. Maybe there was a breif glitch or reset server side. Maybe PEBKAC on my part.

Anyway, just waiting for work now.

Thx again for the reply.

A quick follow-up:

No issue I can see on my network, since I just did a quick successful "attach and detach" to another BOINC project.

I used the URL as directed on this site's frontpage:

http://www.cosmologyathome.org/

Can I assume this is the correct URL?

If so, then it's possible there may be a problem on the server side.

Ageless -

Thx for the quick reply.

I'll take a quick run thru on the port configs. I always have Defender disabled by default (I just use a hdwr router as a firewall, and AVG antivirus).

Since BOINC's inception I've never had an issues with my router or s/w security apps...well, until now!

Thx again.

Guys -

I just upgraded to BOINC 5.10.20 after a short absence here, and cannot (re)attach.

Bringing this to your attention in case this is a problem associated with the beta/CAMB 1.27 cutover that you may not be aware of.

Regards,

Eddie

It looks like the errors are much less frequent now, but I\'d like to hear from you guys: have you had a lot of problems in the last 12 hours or so with errors popping up?

27 WUs since 13 SEPT 01:56 UTC - No errors.

Just some feedback:

My memory is faulty; I forget that this version of CAMB only has 5 output files, instead of 6 with the new version that I haven\'t released yet. Therefore, the template file is wrong.

Anyway, I corrected it. Let\'s see if this helps out.

I was getting consistent *cannot rename file* errors on all recent WUs created prior to your correction described in the quote above (approx 100 WUs). Immediately, following the timestamp of the quote above, all my new WUs have run normally and completed w/o errors (11 consecutive WUs).

ref: My results log -

Perhaps a nexus?

My system:

Intel C2Q G0 stepping
Intel i965P Chipset
Win XP-Pro SP2
BOINC ver 5.10.13

Hope this helps.

Hi -

I am having exactly the same symptoms as Saenger.

The new WU's d/l, or attempt to d/l, and the WU's seem to attempt to start, but there is no time incrementing/decrementing displayed under the "Task" tab of the BOINC mgr. The BOINC mgr then freezes up for a minute or so, and the newly d/l'd WU's status changes to "computation error".

This occurs with every WU downloaded since last nite (several dozen).

My system:

Intel C2Q G0 stepping
Intel i965P Chipset
Win XP-Pro SP2
BOINC ver 5.10.13

Hope this helps.

Best regards.

For reference, here's the msg I'm seeing in the BOINC mgr whenever I get a WU that immediately errors out:

9/12/2007 4:06:09 AM|Cosmology@Home|[error] Can't rename output file wu_091107_190054_13_0_0

Perhaps this may assist in diagnosing the issue.

Unless I have an issue that's unrelated and specific to my machine?

Hi -

I took a two credit hour astronomy class given by the Planetarium, which also fulfilled one of my undergrad DePaul University "free elective" classes. It was great. The class was taught by one of the chief astronomers managing the place, who also was one of the guys running Northwestern University's Telescope.

FWIW, there are also public tours of Northwestern's telescope given on Friday evenings (check out website), and it really is a blast-into-the-past experience of old-school turn-of-the-century astronomy! The building still has lot of the original construction, and entering it has the aura of walking into early 20th century astronomical observatory (unintended, I'm sure)!

As for the Alder Planetarium, well, what can I say? It is a real jewel; I highly suggest a visit by anyone passing through, or visiting Chicago. Great for children, too, but still some interesting enough for adults. Not sure if they still have classes offering telescope viewing time, or University credit. Been a while for me, too.

I read always Beta! I thought Cosmo is still in Alpha!?
Or have I missed something?


Alpha - Beta = Samo Samo, theres not much difference really ... :)


Well... ThereĀ“s a big difference! One starts with A, the other one with B... ;-)


hehe ... Well they should just go up the Alphabet, Alpha - Beta - Crash & Down because that's how a lot of the Projects seem to go ... ;)

* Alpha testing is simulated or actual operational testing by potential users/customers or an independent test team at the developers' site. Alpha testing is often employed for off-the-shelf software as a form of internal acceptance testing, before the software goes to beta testing.
* Beta testing comes after alpha testing. Versions of the software, known as beta versions, are released to a limited audience outside of the company. The software is released to groups of people so that further testing can ensure the product has few faults or bugs. Sometimes, beta versions are made available to the open public to increase the feedback field to a maximal number of future users.

Agreed.

This last set of definitions also accurately describes these terms as used in a hardware (not nescessarily I.T.) development project.

The alpha product is the final finished working protype that resides in-house (the culmination of the R & D effort).

The beta product will then be the initial limited release product to specific qualified cutomer intallation(s).

After validation on/at the beta site(s), the product then goes to full manufacturing release (RTM).
