WCG Challenge Help Conquer Cancer (1st/2nd week of November)

[animal007uk]

Hi team, i am back home from london now and have so far run 2 GPU work units since being back on windows 7 .

I would like to try for 3 but CCC reports GPU usage at 98%, Is there anything i need to change in boinc options if i try to run 3 GPU work units?

Thanks in advance
Steve.

Very awesome of you!!!

I'll add it to the prize list

I personally have not changed anything in BOINC options. Just changed 0,5 to 0,33 in app_info.xml.
Do not be afraid of 98% usage. WU completing will take a bit more time.

To animal007uk just go for it. I experienced a slight lag in some programs (GPU heavy ones) but that's all. It had 94-95 % (one GPU unit at the time) before and 96-97 % now (3).

I noticed that KieX pick up in speed again and took away my blue berry pie so I changed my second 7770 to three GPUs. Let's see if it works this time.

Edit: I had to reduce CPU to 60 % (i7-970/12 to 7 "cores") to get a balance in GPU /CPU units. Went fro 250/280 W to a fairly constant 240 W for +10k PPD (maybe). I did the same in my i920 (8 to 6) to get that to work as well. No readings there but CPU temps went down.

Had a few noob mistakes the last few days trying to OC. Hopefully back at ~94K now that I left it at stock.

Thanks all will try it now and see how it goes :-)

The CPU OC is 21 x 200MHz.

That's actually slower than I'd expect--a bit longer than my GTX470.

What voltages do you need for that level of OC?

I have no idea what that is, but thank you!

Just keep us posted on how it's doing
I'm eager to try multi WUs on my HD7770 when it arrives

Thanks for all your contributions t_ski!

[KieX]

So this is a little bit of a tangent.. but wanted to give a big thanks to everyone contributing to this challenge. TPU is reaching new heights with your help I hope you catch the bug and stick with us a little longer after too.

For anyone who would like to know more about what all this (fun) scientific contribution is for there is a video here from the scientists explaining what they do with your hard work:

Another amazing day team!


I don't see us losing this competition at this point

[t_ski]

Dang, that's one heckova lead!

So far it all seems to be working fine no crashes or errors that i can see :-) All i need to do now is sort out my power options to stop the pc going into sleep mode at night when i goto bed.

Happy with the tempretures to, CPU = 54c max and GPU = 50c max

I am also going to see what happens if i try and do 4 GPU work units :-)

It is running at 1.360V on the core. The rest of the voltages are unchanged.

I sent a PM over to the54thvoid to see if he'd join us. He's got a pretty similar system to mine, except he only has two 7970's.

[the54thvoid]

So what do I have to do?

Software to download, how to register etc....

[t_ski]

Thanks for stopping by!

Start here:

And add in your GPUs by doing this:

http://www.techpowerup.com/forums/sh...d.php?t=174138

Post up in eaither one of those threads if/when you have questions - I'm new myself, but was able to get this up and running with everyone's support.

[the54thvoid]

Well, I'm up and running, seems to be just CPU for now. I see I can change CPU utilisation. It's at 60% for now is that right in terms of allowing other tasks or what are the basal requirements?

Also - How do i add the gpu's in? And how many WU's should i run?

GPU WUs you can enable on the "My Projects" page, just check off enable GPU Workunits for my devices. Just make sure you have a supported card.

You can run the CPU at 100% without any problems during normal usage.

[t_ski]

The second link I listed above talks about adding a custom app_info.xml file that will allow you to fun multiple work units per GPU. You can probably start out with three each and move to four or more as you feel comfortable.

[the54thvoid]

Hmm,

Noobishness approaches.

1: Create new profile on wcg site with HCC only and make it default.

How do i do this exactly? I don't see a create new profile option. Does it mean, create an entirely new profile from scratch? If so, can i still use the same e-mail address?

[t_ski]

No, you can just go into your profile and uncheck all the other options besides HCC, then save it.

Welcome aboard the54thvoid! It would be amazing to have you--with those GPUs doing 4 WUs each, you should be top-3 easy!

[the54thvoid]

Last question.

Which app file should i use?

The HCC for gpu only or the one with HCC for gpu and gfam for cpu. I'm guessing it's the gfam one?

Just run the one with the HCC GPU only. The CPU will do a fraction of what the GPUs do (like 5%), and this will let the CPU run cooler. And if you're going to be running 4 WUs/card that will be a sufficient load for the CPU anyways

[the54thvoid]

Hmm, nothing seems to be happening.

I'll work on it later.
