I run three at a time on my 970s/980s, but I have it setup to run no more then 2APs at a time, while a MB will always be three per card. I'm sure the GPUs will run three APs at a time but I'm going for stability rather then speed. So I use .34 for the APs and .32 for the MBs, works smoothly for me.

I recently took foundership for Team RivaZone. There are 157 members, 5 with credit, 1 active(me). Team RivaZone is one of the earliest Seti teams formed March 1st, 1999. The team motto "Gathering RIVA users and their high-end CPUs for a little "extra credit" when not tearing up the latest 3D game." remains.

I figure there may be some users out there that remember this team and or site and may want to join/rejoin. If your one of them welcome aboard.

I'm curious, do you have any pictures of your current build? Would be fun to see your system coming together.

Looks good, maybe wait and see what the GTX950s will be. 750Ti's price may be reduced to $99.

Thanks for the information. The settings I choose to use were a mix. Using Zalster's command line, and Jeff Buck's app_config, which I applied in the app_info. The system is running smooth right now. I have max_concurrent set to six. My cpu utilization with the gpus running one MB and one AP each is around 50%.

Now here's a good question, has anyone had a 960 lock up from running three APs at a time? I ask this because I have a machine with two 970's and a 960, with MBs and APs set to .33, it hasn't locked up yet. I really like these 960s, there like little tanks.

On a side note I picked up a Titan Black to mess with, I'm guessing the settings for a 980/970 would be ideal for it. Anyone run one of these cards? its a hot little monster, but it really idles down when crunching APs.

My rig with two 750Tis locked up again this morning. It only does this when running two APs at a time.
My command line is as follows:
-use_sleep -unroll 10 -oclFFT_plan 256 16 512 -ffa_block 12288 -ffa_block_fetch 6144

Are there more conservative parameters that can be changed for this line?
Should I just change my AP tasks to one per gpu?

When I get home I'll be able to reboot the machine and if I can't find a stable solution for these AP tasks I may just remove astropluse and just crunch MBs on this machine.

Thanks for any help,
Todderbert

I do believe the Governments know more than they let on. Personally I think the term conspiracy comes to mind as in they don't want us to know what they know.

This comment should be in the politics thread really :-)

There is no conspiracy in regard to SETI,

Not from Seti itself, no. But it would likely be restricted in publishing stuff that the "government" didn't want public.

I'm happy to continue crunching. I have no more or less hope than when I started nearly 15 years ago!! And in any case the camaraderie here amongst like minded people is far better than anything on Facebook or Twitter.

So knock off the negativity folks :-)


Maybe we could start a Gaining Hope thread.

I'm with you on the happy to continue crunching. The real challenge is explaining to my wife why I need another rig.

I was most excited when I read about the team getting scope time. Money makes things happen, and I felt elated that they can now point the scope where they think ETI may be. I'm sure listening to the recent water worlds found would be a nice start. If our computer resources are allowed to help search this huge new influx of data, it will be amazing.

Nothing like Search, pcie expansion chassis mac


I like that unit. Horizontal mounting with spacing between cards...bonus handle on top.

If you are going to mix then go with the setting for the lowest gpu. I think the read me file in lunatics talks about how to set. I cheated, went to the source. Mike. Back when all these started to come out, we were quizzing him about what settings to use. He will probably be along at some point. He's over in Germany if I remember correctly. But my memory tends to be faulty lol

Keep that 960 with the 970. Think the 750 is too low for them.


I was thinking of running the three 960s all together, and just running a dual 970 for now. I found a mini 970 but its an ASUS with a backplate, looks like it would be pretty snug against the reference 970.

I'll have to read that txt file about the parameter settings and figure it out. A dual 980 build will be happening soon.

Fired up Team Viewer at work here and logged in to fix that error. Thank you Zalstar. Being a newb to this AP setup, is there a chart to use for different GPU configurations? I have one machine with 2-960s w/1-750, and another with 2-970s w/1-960. If mixed cards will cause a problem I can pull that 750 and move the 960 over to that machine.

In the last week I have had major issues with two of my machines. Both machines are Intel 4690Ks running two 750tis SC in each unit. Tuesday morning one of my machines greeted me with a black screen of death, no response or communications on the LAN, had to hard restart. This morning my second machine was wailing away at 100% fan usage on the GPUs, turned on the monitor and had a frozen desktop with no response. Had to hard restart that one too. Looking through event logs and found no errors on why the lockups occurred. The coincidence was that both machines were running 2-APs on a single 750ti at the time, also I had added this line suggested by Zalster just before the problems:
ap_cmdline_win_x86_SSE2_OpenCL_NV.txt
-use_sleep -unroll 28 -oclFFT_plan 256 16 256 -ffa_block 12288 -ffa_block_fetch 6144 -tune 1 64 4 1 -tune 2 64 4 1 -hp

These machines have been rock solid till now. They are only a month or two old so there is no dust build up and the line voltage to each machine is good.

So I'm leaning on the idea that 2-aps per 750 is too much, and/or the parameters above might not be the perfect command line setup. Any thoughts?

Looking at the 780ti, and 980tis they consume the same power as your titan Xs. I'm already heating up my basement with just my 960/970s. After I get my dual 980 setup going Ill look into the 980ti in the fall, hopefully after a price drop.

Loving that Outlander machine. How well does your Titan run Seti tasks? I was looking into used Titans, and Titan Blacks for the double precision for other projects.

Besides the -use_sleep parameter, switching to the latest r2887 app might help. I've noticed that the CPU times for AP on my xw9400 just about dropped off the charts with r2887. That box has a couple GTX 660s and a couple GTX 750Tis.

Did you notice a difference in completion times for the AP units?

Virtually identical times, maybe even just a hair better, on 3 of the 4 GPUs. For some odd reason, though, one of 750Ti cards is taking about 50% longer. I haven't taken the time to research that yet. I suspect something else is going on there.

If I were to add this new app to my folder and make the changes to app_info will it dump my current AP tasks?

Zalster,

I looked at my APs results and compared them to yours. It seems yours run with 10% cpu and mine seem to run at 100%. Same as Cliff's. Am I missing a setting? My MB cuda tasks run the 10% cpu. I'm running my 970's .33gpu/.5cpu.

Not meaning to shift this threat off topic I just had a look at one of the tasks and noticed that they were running for over an hour for an MB task this seems really long. I run 2 tasks and a time & the Max I have seen a task run for I think is about 15 minutes. Settings are 0.5 for both GPU and CPU



Who's tasks Speedy? Mine or someone elses? MB task or AP task?

Todderbert & it is 4263183147 I was referring to


Yes, I noticed this behavior when the AP tasks would start the MBs would begin to slow, got worse when 2-APs and 1-MB was running. I applied the command line configuration that Zalster provided, noticed a change right away with my cpu utilization falling back down to a normal level.
