I have one team member that has picked up a -24000, and another that has +24000. Something going on that\'s for sure!

This wu after 32 hours had crawled to 1.6% complete. Obviously one of the crawlers, so I\'ve aborted it.

On my quads, I let it download some wu\'s, then set the project to \"No New Tasks\", then \"Suspend\" all but, (say), one of the wu\'s. When that wu is finished, I \"Resume\" another. So on until they are all gone, then I download some more.

That way I can have however many CPDN wu\'s running as I like. With the real long deadlines, having a few non-started wu\'s lying around for a few months is no issue.

IE7 is CPU hog only if one of pages contains really nasty javascript,so badly written,that it needs huge amount of proccessing.One of the more visible is \"falling snow\".If no such script runs IE7 is really inactive...

There are other reasons IE can hog resources if left running. I had found that if I used a site which required the QuickTime plugin, sometimes IE would seem to freeze but the Task Manager shows it using very lareg amounts of CPU.

Whilst I appreciate this is not an IE7 problem per-se, a casual Windows user will not necessarily comprehend the plugin concept - to a casual glance, IE7 is using the CPU.

Always remember that there are people out theer that just turn the machine on, press the button the usually press and wait for the result, they do not consider the machinations or consequences of their actions.

*** EDIT ***

Uninstall/Reinstall QuickTime fixed this particular issue.

Grabbed a new model, this one, an \"SM\", and it appears to be running as expected. It has sent a scoring trickle, which upon back calculation gives a c/hr of 23 as expected.

I will allow the model to complete and then force it to run a \"CM\" to see if the problem was specific to the original configuration of the machine, (and/or any resulting fallout), or generic.

Okay, I\'ll abort this one, which I hate to do, and get another to see if it performs better.

Following up a bit, I found an issue with the disk drive, (more specifically with the disk drive cable), which was generating a few errors in the event log. This is now fixed so I switched the model on again to see if that was the cause.

When I did, it dropped from 1.101% 78:38:20 back to 1.092% 77:38:05, (machine had been down as I was replacing the cable). I let it run for an hour and it went up to 1.101% at 78:41:02 so basically it had crunched 0.009 in just over an hour.

If the trickles come at 1.38% intervals, that gives ~153 hours per trickle, or roughly 2.2 credit per CPU hour, which is a long way from the 23 c/hr quoted earlier.

The assumption there is that the progress per unit time is a straight line - is that a fair assumption, (or within reason anyway)?

If so, I do not understand the stupifying under-performence of the wu on this box. Projects like POEM, Einstein, Rosetta, MalariaControl, SIMAP etc. are producing much the same RAC as my other Q6600.

It is not lack of resources. The task is using less physical and virtual memory then several of the other projects. The 2 machines have different MoBo\'s but one is a top notch Asus, the other an equally good MSI. RAM is the same, disks are the same, OS is the same, graphics cards are the same, heatsinks are the same, clocking is the same. Cabinets are different colours ;)

Weird stuff going on in North Sjælland.

I\'ve suspended CPDN right now. I\'ll play around with it a bit more as time permits. Some of the numbers I needed have come out of this thread anyway, so I know what I should be seeing.

I have just run several passes of the diagnostics I use, and the h/w seems to check out. What is odd is that I can\'t access the Windows EventLog. I am re-installing Windows at the moment.

When I first built it, loaded Windows and BOINC, I left it running for 3 days crunching just SIMAP. It was RAC\'ing over 2000 a day which is about right.

<fx>Shrugs</fx> Beats me what\'s up. It is ripping through Rosetta, SIMAP, MCDN and POEM. There are a couple of other projects on there with very small quotas, but even they are churning work out.

It says in the graphics that it is on step 8069 of 259248, 1.04% crunched, and 71:19:41 of CPU time to get there.

The 1GB is an unfortunate temporary situation. When I ordered the components for this system, I had ordered 2GB of Corsair 4.4.4.12 RAM. Upon building the system and testing it, Memtest-86 v3.3 showed a fault in the RAM, which moved upon swapping the modules around. It has been sent back. The result is that the machine running CPDN is running with a stick stolen from this machine, (another Q6600). At this time, the system is not overclocked, although as it is a G0 chip and has a huge Zalman on it, on a top-notch MoBo, it probably will be when the right memory arrives.

There does not appear to be any commonality between the messages preceeding the trickle-up. There are 10 projects on the machine, and most of the messages refer to regular events from these. Suspending, Restarting, Uploading - your familiar with this stuff. Just searched stdoutae.txt, no memory issues, just the confirmation of memory usage when BOINC starts and reflects the defaults for the location of the machine. No apparent errors.% done seems to be gradually increasing, not jumping about.

Is showing 25% CPU use, as expected. Similar resource figures as POEM, about half of what Rosetta is using. Remember, the model is fairly new, ISTR that the demands go up as the model progresses. Leave in memory is set as usual, no graphics running.

If, as you say, it will not generate a \"real\" trickle until it gets to 1.38% then that is probably why, since it has not. I am suprised to see it performing as poorly as that however when other members of my team with regular hardware are getting scoring trickles every day or so. If the machine trickled now and got 311 for it, that would be a credit/hour of less then 5, hugely below what it is acheiving anywhere else.

I have trimmed the \"got 0 new tasks\" and \"requesting...\" parts of the messages to prevent phattening.

The models have changed since I last ran CPDN. It used to run with 30% quote on a 3.2GHz Prescott HT. In that rig, it got pretty much 1 trickle per day. It is now running at 25% on a 2.4GHz Q6600, so basically has exclusive use of 1 core. I would have expected significantly more to be done per 24 hour period in this rig.

These \"I\'ve resumed\" trickles must be something new, I don\'t recall them when I was running CPDN before. The \"real\" trickles must be larger then the old. The model is at 1.022% so is probably why there are no trickles.

I can see other people getting trickles reasonably regularly however, and getting 311 credit for them. See link in previous post.

I picked up this wu a couple of days ago. I can see it sending trickle_up messages, yet the result shows \"No Trickles\".

I saw that there had been some credit problems around Christmas, but can also see that my team mates trickles are appearing normally.

Anything to check?

I seem to recall my RAC dropping when I went from regular slabs to Sulphur cycle, that was never addressed.

I can already see the rankings at a couple of the big team sites being screwed about. I suspect there will be more said about this.

Surely everyone should receive a boost then not just a random few.

If you look at the stats page I linked, you\'ll see some who regularly contribute get nothing, others that have not contributed at all recently have got some, and variations in between.

I seem to get 160.7 credits per trickle incidently.

A large number of my team members received a sudden influx of credit yesterday. People that normally earn 3-400 per day yesterday received thousands! Not everbody was so blessed, others that get credit every day received their normal quota.

My current Sulphur Cycle model is grinding enexorably to completion. When the last one finished, it downloaded a new Sulphur Cycle. I see, however, that there are 3 different \"projects\" now, the Sulphur Cycle, BBC, and Seasonal Attribution.

Can I chosse what to do when the current model finishes, or will it just download another Sulphur Cycle wu?
60) Questions and Answers : Windows : RPC error. (Message 23272)
Posted 21 Jun 2006 by Profile adrianxw
Post:
The CPDN server is not responding correctly to the officially published team_email_list RPC. Rather then returning an XML list of users/userdata for team \"n\", it returns an error stating that only a team founder can edit team details. This is incorrect. At other projects where I have found this error, it was traced to outdated PHP files.

Note: I am using the prefix returned by the get_project_config RPC.
