Message 48567 - Posted: 8 May 2011, 6:26:04 UTC

It looks like more than a few people are still having a problem where clients are aborting workunits early because of max time limit elapsed.

If you could post here with any information about your client (and if you're using an anonymous platform or anything like that), I'd appreciate it -- so it's all in one place for us to look over.

Is anyone having this happen for the CPU applications, or is it just limited to the GPU applications?

Message 48568 - Posted: 8 May 2011, 6:41:05 UTC - in response to Message 48567.

The two most recent configurations (from about an hour ago) for me:

ATI HD4850
BOINC 6.10.58

One -- Windows 7 64 bit
The other - Windows XP SP3 32 bit

What I saw on both was computation errors.

Seems only an GPU App Problem.

I've tried increasing the RSC_FPOPS_BOUND of newly generated workunits. I'm hoping this might increase the bounds the clients are calculating high enough so they won't automatically be canceling workunits. Let me know if it helps.

ok i will try now. Wait some minutes for my answer ^^

Edit:
After 9:11 Minutes ~ 75%
I think it runs longer then last times (~55%?), but still not long enough.

Message 48588 - Posted: 8 May 2011, 12:12:20 UTC

I am wondering what kind of points are allotted for the N-body projects. I've noticed that they start grabbing processor threads before they even start running. This shuts down processing on my other projects and reduces productivity on my machines. This type of project grabs all the processing threads of my 12 core system. If the points are high enough or the project important enough then OK. Please advise.

I am running only GPU

windows7, ultimate x64
12 GB ram, i7 960
2 ATI 5870, driver 11.3 BOINC 6.10.58

The first time I had errors was May 7 in the afternoon when I started the rig after a few days off.

The n-body workunits are multi-threaded -- so they'll use all cores that are available AFAIK.

The first 4 have made it through my 5870 CF rig. Your fix seems to worked. One question. Why are they running High Priority, they are only 2 minute tasks.

Running CPU only, have had several workunits fail.

My client is shown in my stats, and the errored workunits listed, as of this post.

Originally, I was experiencing the "timed out" error and the WU's only had an estimated time of 0:00:06 to 0:00:10 each. There was a fix applied and the times then went up to around normal - around 3:30 to 4:00 each.

I had approximately 10 old WU's that were downloaded around 2:15 a.m. EDT (5/8). I opened one up for work and it timed out as before, and I received new 2 WU's around 1:30 p.m. EDT (5/8). The first one downloaded and was completed, as well as the second one.

When the second one was completed, I was given ONE new WU instead of having the usual limit of 12. I'm not complaining about not getting any work, just advising of what's happened.

Here's my rig's information:

BOINC Version 6.10.58 - all programs are NOT OPTIMIZED
Platform: Microsoft Windows7 64-bit Home Premium
8Gb RAM
Intel Core2 Quad Q8400
ATI HD4850

I am also attached to PrimeGrid and Collatz, both using GPU.

Hello Travis,

This is about GPU

I see a few strange things:
1. The WU's run complete again without error but are 2 to 4 times longer. 2 to 4 minutes instead of 1.12 it was last week.

2. I got 24 new but they were not going to MW. I did manually. After all complete I got one new and one was runnig, so one ATI card has nothing to do. After half an hour I got 24 new ones, but they are not moved and replaced by new ones as last week.

3. The runtime is very variable but the cpu time is almost the same variing around 6 secs. Credits seem te be granted by cpu use and not the total running time.

4. High priority is gone now.

5. BOINC has an estimated run time of 2 hours, 21 minutes, 40 seconds for the WU's who take between 2 and 4 minutes now.

Windwos7, ultimate x64 12Gb RAM with 2ATI 5870 driver 11.3 BOINC 6.10.58 stock app, no modifications or tweaks and no anonymous client.

Have no problems at all with my HD6970 (cath 11.4 preview)

There is some lag, but I don't care.

The n-body WUs are failing due to maximum time limit elapsed. Everything else is fine. I have Win7 64-bit, an Intel Core i7 980X, and a Sapphire Radeon HD 6970. I am using BOINC 6.10.60. My Catalyst drivers are the 11.4 production drivers. I am using stock everything, no app_info.xml, and no overclocking whatsoever.

All WUs fail after 2 seconds.

I think the problem for my computer is the problem related here:
http://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=2345

My CPU don't support SSE2.
Can you do something pleas?
