1) Message boards : Number crunching : combining video cards (Message 1424845)
Posted 298 days ago by Profile Tazz


I will probably catch a lot of heat for this, but using .5 CPU core I am running 2 APs on each of my GTX660SC with no problems. My AP run times seems to be consistent with both your GTX660Tis and the GTX680s, and your GTX660Ti has more memory than my 660SCs. It really seems inconceivable to me that I'm the only one with a Fermi or newer card doing this and why every one is insisting on using 1 core for each AP task. Regardless to what everyone says, I've been running this scenario prior to v7 with no problems, so I think I've shot that requirement in the head. If your card has the memory to deal with 2 AP tasks, I see no reason to use a full core for each task.


I'm currently running 2 APs on 3 GTX560s spreads over 2 computers. A GTS450 also runs 2 with no problems. It's all setup to free up 1 core when the APs start. The run times on the GTX560s seem OK at 2300-2500 seconds. The times on the GTS450 varies a little more, 3000-4000 seconds on %0 blanked APs.

I just calculated my main machine to be at $1.75 a day crunching.

1.75*365=$638.75 per year.

I'll stop there, to add up the 4 other machines *might* scare me.

I was wondering the other day how much I was spending in power for S@H. I decided against calculating it out because I knew that I would try to talk myself into cutting back.

Electricity cost for me is $0.13790/kWh

I'll Try to get stable build the GPU did get work by stay at waiting to start.



Double check that "Use GPU while computer is in use." is selected in the local preferences. OR "Suspend GPU work while computer is in use?" = NO on the website preferences. Whichever prefs your using.

OK, I thought that I was beginning to understand how this worked but something don't seem right. This is the app_config that I started out with:

<app_config>
<app>
<name>astropulse_v6</name>
<max_concurrent>1</max_concurrent>
<gpu_versions>
<gpu_usage>.51</gpu_usage>
<cpu_usage>1.0</cpu_usage>
</gpu_versions>
</app>
<app>
<name>setiathome_v7</name>
<gpu_versions>
<gpu_usage>.49</gpu_usage>
<cpu_usage>.06</cpu_usage>
</gpu_versions>
</app>
</app_config>

From watching it run on two of my hosts I concluded that <max_concurrent>1</max_concurrent> will only let 1 AP run at a time so I didn't really need to divide up the GPU with the .49 and .51 since there's only one GPU in each of those two machines.

I changed the GPU usage to .50 for AP and .50 for MB (and yes I did save it), with BOINC running, and then did the "Read config file" command in BOINC. It's still showing that they're using 0.06CPUs + .49GPUs. I restarted the computer and it's still showing the 'old' settings.

In another host I have 2 video cards so I changed to <max_concurrent>2</max_concurrent> and left the .51 and .49
I'm thinking that this will not let 2 APs run on 1 GPU, but I'll have 1 AP and 1 MB on each.

In the task list for your computers.

OOhhhh, Ohhhh, I got one. Let's see what happens!


That one went well. It stopped 1 core to use and ran along with the MB task. 8269.98 seconds validated for 815.85 credits.

I added -unroll 10 -ffa_block 6144 -ffa_block_fetch 1536 to the ap_cmdline_win_x86_SSE2_OpenCL_NV.txt file. That will work, right?

I've got everything selected to do AP, just waiting for some. I do not have any command line parameters set because I have no idea what they mean.

I think you can just ignore those words.

With this design, the max concurrent also impacts the cpu tasks - I wish the design was different.


Here's what I've got:
Lunatics app_info for MB only. <count>.5</count> is the only change made.

This app_config:
<app_config>
<app>
<name>astropulse_v6</name>
<max_concurrent>1</max_concurrent>
<gpu_versions>
<gpu_usage>.51</gpu_usage>
<cpu_usage>1.0</cpu_usage>
</gpu_versions>
</app>
<app>
<name>setiathome_v7</name>
<gpu_versions>
<gpu_usage>.49</gpu_usage>
<cpu_usage>.06</cpu_usage>
</gpu_versions>
</app>
</app_config>

After I check AP in the .41 installer do I have to change anything in the app_info? Just the <count> back to .5 for MB?

BTW I already have 'Use at most %50.00 processors' leaving 1 free core. Does this look like it might work, I don't want to trash a bunch of work (again) not knowing what I'm doing.

Going on 14 years of Classic and MB crunching I would like to wet my feet in the AP realm but I'm not sure how to proceed. Yes, I know I check the box in the Lunatics .41 installer (GREAT job BTW guys) but Where/how is it easiest to control how many to run on GPU only? app_info or app_config or what combo of both?

I want to try on a dedicated cruncher that I just put together from spare parts I had laying around. Then, after I've got the hang of how it behaves, get it going on my other machines.

Specs: Athlon2 x2 215, GTS450 1GB, 4GB RAM

I currently run 2 MB at a time, I don't know if the 450 has the ummph to do 2 APs at a time. Maybe I should try 1 AP (when available) and 1 MB but still do 2 MB when there are no APs. Where to start?

Thanks in advance.

Posted 330 days ago by Profile Tazz
Not entirely OT, but two of my crunchers have been paired with quite a few of these machines leaving a mess.

This one has 18 Validation inconclusive, I think 5 or 6 of them show the same results. The rest of my wingmen have 1,000's of invalids and/or errors.

This one has 22. I checked some of them and there were a few wu's showing the same results but the most were paired with hosts giving invalids or errors.

We need to come up with a name for these machines giving junk results.
17) Message boards : Number crunching : Boot Sequence (Message 1408770)
Posted 337 days ago by Profile Tazz
Hi Again,

After trying to load linux, how do I boot from USB at startup. I realise that my old computer does not have boot sequence for USB (it's only cd/dvd, hdd and floppy) although it has 2 working USB port. Also, I try not to load linux using virtual machine as it defeats the purpose of running linux while being dependant on windows. Please advise.


You might want to look into Plop Boot Manager. I've been semi successful with it, but I found a workaround for what I was doing and left it.

You'll have to do some reading and there was an example that worked for me, so it shouldn't be too difficult. More or less, what it can do is it makes a bootable iso that you burn to a cd. In that iso there are pointers to your USB drive.

And that's about all I can tell you about Plop. I had DOS on a USB stick and no way to boot from it. I was able to boot from my CD and it gave me access to the USB drive, then I found a different solution involving virtual machines.
18) Message boards : Number crunching : Freeing CPU cores (Message 1401193)
Posted 355 days ago by Profile Tazz
<Thinking out loud here>

I have TThrottle running to keep track of my temps and throttle them down if need be. I've read that TThrottle's more effective/efficient at, um what's the words I'm looking for, CPU scheduling?. Would it be the same thing to set my BOINC preferences to allow 100% and use TThrottle to set the Max CPU% to 87.5 (for an eight core CPU)?

It would be running 8 tasks on 87.5% of 8 cores, or 8 tasks on 7 cores. I would guess it would cause an increase in crunching times for the CPUs, but it still would have a free 'core' for the GPU(s). Right?

</Thinking out loud here>

Posted 357 days ago by Profile Tazz
On a AMD CPU 88% isn`t enough.
At least on a FX 86% is needed.

86 should be freeing two cores - if you have more than 6 CPU tasks running, you've found a bug.


My FX 8150 is set to use 90% and it's crunching 7:
08/08/2013 11:13:54 AM | | max CPUs used: 7

One core should be enough for 2 GTX 560 with 2 wu's each, shouldn't it? The work times are similar to the GTX 560 in my other machine that has a free core (Phenom 9650) and 2 wu's. -- ONLY MB btw.

Posted 357 days ago by Profile Tazz
Has anyone posted the exact meaning of 'freeing up
a cpu core' in relation to gpu usage, and the where
and how to do so? And since there is more than one
way to do it, which would be the best/easiest/fastest
way to do it, in such a way that a newb would understand
it? A faq perhaps?


I 'free up a core' in the local Preferences>processor usage tab. "On multiprocessor systems, use at most ___% of the processors."

I set mine at 90% and it crunches on 7 cores and leaves the 8th free.
75% on a 4 core system will leave 1 free
