Message 1165592 - Posted: 26 Oct 2011, 19:20:47 UTC - in response to Message 1165591.  

Looks like the limits have been raised to 200 CPU/400 GPU.

Nope...
Still 50/CPU core and 400/GPU core.

EDIT...
As I don't have any rigs running with HT on, I am not sure if the 50/CPU core is actually per logical CPU and ends up doubled with HT on.



Can someone then 'splain to me why with 223 wu's on hand (counting the 4 that are mid-crunch) I'm getting "Limit" responses from Berkeley?? My DCF is 1.0435 atm and MB wu's is all I got.

Pc is just a C2D e8400 and 1 460.

You have two cores, so 50 tasks each. The GPU will allow another 400 tasks, but if you are already at 100 CPU tasks, and your rig asks for more CPU work, you will bump into your CPU limit. If it asks for GPU work, you should get more work.

It is using total usable processors. A 4 core machine with HT, 8 usable processors, gets 400 tasks. A 4 core machine without HT, 4 usable processors, gets 200 tasks. A dual 6 core Xeon server with HT gets 1200 tasks!

Thanks, Steve!

I'll pay more attention to what is being asked for. The last 3 requests were for only CPU work.

I also would like the limits removed. The bandwidth seems to be able to handle it and I know my machines would like it. They keep saying that they have reached the maximum allowed tasks.

Actually, your machines simply pass on the message from the server without knowing what it means. A rational limits mechanism would instruct the core client not to ask for any more work until it completes some. That could even be extended so that if the user clicked Update the client could explain it wasn't asking for work because it was already at the limit.

Are you actually running out of work or are you closed to?

If it becomes "normal" like it's running after the memory upgrade on the HE router I personally don't need a large cache anymore.

I'd rather would like to have AP's again. And then lets see how the cricket looks like ;-)

IMHO raising the limits should be last step taken - after all other issues are sorted out.

Three hosts running, each having between 200 and 300 MultiBeam tasks.
Fourth host has trouble with it's GPU and has 46 tasks, which might not make the
deadline.

I'm going to post a guess here. I have read that there are two more fixes for the DCF problem that still need to be implemented. Each one will affect the DCF a bit, so by having lower caches, not as many work units are affected. The work in progress is turning over fairly quickly now, rather than be in a cache waiting for its turn. After the second, and hopefully final fix is in place, and has settled all the DCF's, perhaps then is when the limits will be increased, or eliminated.

That is my understanding as well. They don't want to open the floodgates fully yet, as there is some chance that the remaining adjustments to the server code 'may' goose the DCFs again, possibly resulting in over fetching by hosts until they compensate for the new fudge factors.
So I guess it's kinda preemptive damage control.

So now would be a good time to start sorting out the GPU estimated work time issues...

I am guessing that the next stage in peeling the band-aid off will probably not be until next Tuesday's outage.

they don't have to open the gates all the way ... all they need to do is lift them slightly ... and in doing so will take some of the heat out of the system ... it will take a day or two to settle again however they will establish a new/slightly higher operating position which should see some machines not call on seti as much as they are at the moment ...

Why bother ?? Now that AP is back on we can't download what's already been allocated.

I have units that have been waiting to download for 3 days and downloads are so slow I can't keep up to the current limit. Imagine the chaos if everyone was in "fill my x day cache" mode on top of the current schemozzle ?

Its starting to improve, not by a lot but the shorties are getting fewer and at the rate that the AP's are going out some users caches must be filling up.

Its only the faster machines that are affected by the current limits, a lot of the slower machines or those not running 24/7 will not even be reaching the limit anyway.

I'm guessing someone needs to cough-up another 100Mb furball for AP.

I did run out of CUDA-WUs even during the really short maintenance outage yesterday (local time).

No chance at all to keep even a reasonable amount of workload in the cache, to keep them running I have to babysitting the machines.

EDIT: OH, nevermind...it's the "Pendings" total that they are looking at, right? OK, I got 489 of those atm...I'll go back to watching Star Trek...


Do the " Pendings" count toward the limits ?
I have a quad core and a GTX 460LE GPU , that would make my limits around 600
WU's ?

I have 561 pending and 193 (atm) in processing.
I have had a total of over 800 in that manner... processing and pending combined...

No, not pendings. I was getting limit messages when asking for cpu work and I had 98-100 cpu wu's already in cache. I wasn't paying attention to the fact boinc was asking for more cpu work.

I would like to say something obscene about not figuring out how to delete a double-post, but that would be against the rules.

No, simply erasing the body didn't work. It wouldn't let me post a blank.
