First, let me just say the GPU programming team should be given a bonus. MW@H is insane on two 4870's! 1 WU on a GPU taqkes ~ 3 minutes, whilst 1 WU on a cpu core takes ~ 3 hours.

I'm having this problem though. After a prolonged duration of BOINC running, the computer will "freeze" in a weird state. Nothing is overclocked, and the temps are fine (or at least within specification :| )
My screen will turn "on" but no video display or fans running on the cards as if they are calculating.

Could anyone shed some light on my freezing?

My hardware specs are below:

Gigabyte 790FXT
Phenom II 955BE
4 GB G Skill Trident 1600
1 Sapphire 4870 1 GB
1 HIS 4870 1 GB
80 GB Intel X-25M
700W OCZ GameXStream
Antec 900 two
HP w2408
card reader
dvd burner
MS wireless KB + M
MS Webcam

If there are any logs I can include direct me towards them and I reply with their contents
I ALWAYS keep my drivers up to date, BIOS, and everything that's update-able.

That's pretty strange. I have no idea myself but most of the people who frequent this forum are pretty knowledgeable so I hope they'll be able to point you in the right direction.

Hi,

this not so much an answer but an observation on your problem
i have a similar problem on collatz but not on here
to explain when i used torun 1 4890 card on both projects everything was fine but now i have 3 crossfired 4890's it works fine here and on DNETC but the computer dies as soon as you start collatz for no reason
could be your getting the same problem running more than one gpu on this projects and not on others ?

have i try withthe others like DNETC or COLLATZ and see what happens

best regards
Ian

Have you updated to the latest driver?

How do you "unfreeze" the system? Stop and restart BOINC only? Reboot?

When you restart, you should get new lines in the stdoutae log, what are the last 10-20 lines before this?

Note, always chasing the latest driver version in the case of BOINC is not always the best strategy. The key is to find a stable version that works and then update only when there is pressing need.

I am running 8.723.0.0 which should be from the 10-4 driver package.

which projects are you running on the GPU? MW only?

Well, here's a little update:

I guess because theres a gremlin hiding in my computer, it was having a bad day. I left it running over night and this morning everything is fine? I have the latest 10.4 drivers installed and BOINC is running 6.10.18. here is an excerpt from when BOINC opened last:

I'll keep a watch on the system, and if it becomes unstable again I'll repost. Thanks for all of the quick responses!

Um, we want the 10-20 lines BEFORE this ...

But only when it has acted badly ... those lines may tell us which tasks are causing the problems...

Anyway, for the moment you are running ...

Having the freezing issue also, but I think it basically started when I started running Collatz with MW and DNETC also. Seems like sometimes when it switches from one project to the next it gets a brain fart and freezes up. Didn't notice any freezing first few days I had the new setup running, and never freeze ups with the old setup (2 x GTX285s vs 2 x 5870s). Running 10.4 driver also.

Well, it's apparent that my gremlin likes to play hide and seek! I would post the lines before that, but whenever it messes around, I obviously don't have the chance to copy them before it crashes.

I'm going to try a few things before I post back. for one, I'm going to disable crossfire and see if that makes a difference. Second, I'm going to underclock the cards to say 700/900 as opposed to 750/900 and see if that makes a difference.
Anyhoo, we'll get it straightened out eventually.

Thanks!

You have to look in the BONC Directory and there is a file, it will contain all the log output from prior sessions ... it then "rolls-over" into an "old" version ... so you have two sets of log files there ...

I usually copy the file to the desktop rather than try to move it, and then use my favorite text editor to get the lines (TextPad)... You can also extend the size of the file so that it will log longer in case you have to go back for an extended period of time or if you have turned on lots of debug flags to try to show issues to UCB ... not needed for this exercise ... The file name is "stdoutdae.txt"

So, for example:

20-Mar-2010 10:33:18 [Leiden Classical] Sending scheduler request: To report completed tasks.
20-Mar-2010 10:33:18 [Leiden Classical] Reporting 1 completed tasks, requesting new tasks for GPU
20-Mar-2010 10:33:22 [Leiden Classical] Scheduler request completed: got 0 new tasks
20-Mar-2010 10:33:40 [---] Exit requested by user
20-Mar-2010 10:33:41 [---] Received signal 15
20-Mar-2010 10:34:06 [---] Starting BOINC client version 6.10.43 for x86_64-apple-darwin

You can see the end of the last session where I asked it to exit, and where I started BOINC again
