Guide to running multiple GPU work units

I'm confused?

Try removing app_config.xml, letting BOINC download work and the executables, and then adding it back.

Well, did that, and after resetting a few more times it finally kicked in. Back to crunching hcc gpu wus! My poor cruncher only has 2gbs ram in single channel as I had to lend 2 sticks to a friend, but seems to be doing okay anyways. My mother comes back from the cancer clinic in a week, seems most of her cancer is gone now. Got to find an answer before it comes back again!

I've not been active much but I'm back crunching here and there so we'll get that answer soon!

2GB single channel is fine--I'm running my i7-920 like that

I wish her the best!

Due to the upcoming outage WCG made some changes- looks like they are allowing us to cache 5,000 gpu wu's

Great, the first time I shut down since these HCC WUs and this happens

The major shutdown isn't due to start until Tuesday AFAIK so you should have plenty of time to fill up your buffer when you get back on Sunday.

FYI- I opened up my buffer and the wu's started flowing in like crazy!!! I must have added 1000 of them to each rig over the last 15 minutes

How do you open up the buffer?

Also, I am currently running the Catalyst 13.1 drivers. WU's are running about the same, 8 to 10 minutes each for 8 at a time, however what I have noticed is my video card is running 3 to 4C cooler than it was!!!

Just increase the Minimum and Maximum in the network settings tab:

That's what I'm talking about, thanks. Looks like Sunday I'll start stocking up on WUs

Thanks Norton! Do you have to set that on every system?

Yes

[johnspack]

Just to be certain, I also set the buffer in Workunit Cache Settings to 4 days in the device manager. Not sure if it does anything or not.

Left from previous versions. Minimum buffer is the important one according to SekeRob (take a look at WCG forum for more information).

Edit: Didn't get my sig right. Any suggestions to do it correct?

It is the first time I hear that something like this exist. I did some fast reading on wikipedia.

So is this all about giving away your computer's GPU power (when idle) to the benefit of scientists doing projects around the world (and that cant afford to buy a computer themselves) ? Or am I missing something?

That's basically what we do- distributed/grid computing for research on humitarian issues (clean water, clean energy, cancer research, etc...). The gpu project is new but the results have been tremendous, especially for Radeon 7xxx cards. All of the other projects currently run on cpu power.

So are you (or anyone in the forum here) part of the research team/teams?

I'll gladly give it a go with my 7970 in 2-3 weeks when im done with the heavy university workload i got atm. Hopefully I will have my system available for this program from now until summer.

You got it right including the part of not having the money to buy their own computer. The computer power that WGC (and other projects) get from donors amounts to millions of $/EUR. We are talking about several Pflop/s aka a top 5 super computer. Most of the people that contributes give their free CPU cycles (marginal cost in electricity) and then there are some that invest a little or in some cases a lot in building dedicated PCs to help accelerate the cure of among other cancer.

I was new to this 3 years ago as well but the decision to join wasn't hard. You can contribute with as little as you want. This is a good starting point http://www.techpowerup.com/forums/sh...d.php?t=106593

Oh right, so it is about very big projects that are split in very small parts which are then sent to many individual PCs for computing. Very interesting.

Just a heads-up for those thinking about switching to the 13.1 drivers, see my post over here:

Anyone else try them out?

Yes I run it on one rig (my 2x7700/i970). I installed it yesterday and so far no problems but it is a dedicated rig......

I don't think those drivers liked my oc of 1100 on the cards. That is the only thing I can think of....

They are literally the 12.11beta11 with WHQL signed and some visual changes to the CCC panel. Oh, also gives my corrupted display in Test2 of 3dMark11, using Displayport.

1100 MHz should be a safe OC. I ran my at 1102 until 10 min ago with no other errors then the sync thing. Now it is 1125 (one Asus and one XFX) at auto fan. The Asus is still at 10% and 50 C. I just love that HS.
