I knew there was something out there, but what I was seeing was that they were adapting the round cooler which did not cover the CPU. Thanks for the additional info.
I may have to bit the bullet sooner than later as I have one system that keeps rebooting one me. I think the first thing I will try next week is a new PS as all temps looks good.

I expect to upgrade to Threadripper........but I have not figured out if the XATX board will fit in a ATX case and since there is no water cooling yet being made specifically for this chip, I am going to wait.
What I will be doing is to take down my farm and relying on one computer.
Amazon had it on preorder but now that it is shipping they are out of stock of both the chip and the MB.
There are so many innovations built into the MB that I am anxious to try them.
Release of necessary parts and finances will dictate when I do the upgrade.

I held off a day to congratulate as I was coming up on what to me is a really great number. Your numbers are just so beyond belief that my contribution seems small by comparison.
But I am so happy with having reached this milestone of 100,000,000.

and I did change the spelling although I am now getting this in the Stdrr: High-performance path selected. If GUI lags occur consider to remove -high_perf option from tuning line
and there is severe lag but it is only a cruncher so it does not matter.

I had to remove the - high_perf option as the system got so laggy that I was unable to do anything with my remote control (TeamViewer).

That's the Com line i use with my 1050ti's running 2 wu's at a time for SOG , Mike helped me with it when i got the cards and after a few days tweeking this is what iv'e been running on computer ID: 7420805
Ain't got a Com line for AP's but run times are ok on the 1050's so ain't to worried bout it

copy/paste of a AP's runtimes all are very similar

Mark, I assume you are dedicating a CPU core to each WU?

Command lines for SoG are not the same commandlines used for Astropulses. You have to have different commandlines for the 2 different types of work units

I did not think of that. But something happened to me.

In your S@H data folder you will find cmdline_xxx_yyy.txt files which will be empty, they go there. There are also readme files for the rxxxx/cuda apps.

For Lunatics SoG it is mb_cmdline_win_x86_SSE3_OpenCL_NV_SoG.txt


Still might be a little confusing. In stock Seti, in the hidden ProgramData/Boinc/projects/seti folder you are looking for a text files that starts with MB*SOG.txt

The minimum you should put in there is: -sbs 192 -spike_fft_thresh 2048 -tune 1 64 1 4

This all assumes you are getting SOG type gpu tasks.

If you are getting Mcuda32/40/50 tasks then you are looking for a file that ends in .cfg which is currently (almost certainly) empty. You should be able to find a file with a similar name that ends in *.sample You can delete the ; from in front of the last 3 lines, paste that text into the *.cfg file(s) and save.

The last step is either click on the "read config" files or restart Boinc.

Now if you are looking for "fancy" for the SOG command line, this may (or may not) produce some faster processing. Please note, this is for a non-dedicated machine. If you are looking to run it as a dedicated machine you probably will want some additional things.
-tt 700 -period_iterations_num 1 -sbs 1024 -spike_fft_thresh 4096 -tune 1 64 1 4 -oclfft_tune_gr 256 -oclfft_tune_lr 16 - ocfft_tune_wg 256 -oclfft_tune_ls 512 - oclfft_tune_bn 64 -oclfft_tune_cw 64
Yes, this is my current GTX 750 Ti as recommended to me by people who have researched this a lot more than me.
The other thing you will want is an "app_config.xml" file to cause one of your cpu cores to be dedicated to driving your Gpu at "full speed."
<app_config>
<app>
<name>setiathome_v8</name>
<gpu_versions>
<gpu_usage>1.0</gpu_usage>
<cpu_usage>1.0</cpu_usage>
</gpu_versions>
</app>
</app_config>
This is also how you arrange to run two tasks on the same Gpu at once. The catch is two tasks take at LEAST twice as long as one task. If they take much more than twice as long, the results are slower overall processing. The trick is to set gpu usage to "0.5" to get two tasks going. This will also tie up 2 cpu cores.
HTH,
Tom

I had been running this cmd line for a few weeks when we started to get APs.....the APs all failed with -9 overflows so I removed the cmd line and now the APs are validating.
(after proving that all was working I upgraded the computer to 1050 ti's from the 750 ti's that were in it. The computer is running much faster, or should I say WUs are processing much faster now.)
Do you think the same cmd line should be tried on the 1050's?
10) Message boards : Number crunching : Seti Not Using Cuda, Einstein Does (Message 1873991)
Posted 19 Jun 2017 by Profile Bill GProject Donor
Post:
Set Einstein to NNT (assume this means no new tasks), set cache to 3 days plus 1 additional and restarted. Not sure if Seti has GPU selected, activity is set to always use GPU . At the moment Seti is using 14 threads and Einstien is using 2 (CPU/GPU) so no change.
.

Just a minor point, and probably has nothing to do with your problem, but you should set additional to .1 not 1. This basically controls how often Seti looks for new work and does not add days of WUs.

Posted 8 Jun 2017 by Profile Bill GProject Donor
Post:
Speaking from personal experience, the app_info.xml is read at the start of computation of each WU so affects all WUs started after you have changed it. I added a command line to one of my computer while SETI was running ant that is what happened for me.

Post:
With my 750Ti's I found 2 tasks had a very marginal gain, BUT losing 1 more core for that small gain was definitely not worth it.
I ran 1 task with -hp flag so it got priority over the CPU.

Is that additional Brent?

I am getting an error in the start of the operation :
WARNING: can't open binary kernel file for oclFFT plan: C:\ProgramData\BOINC/projects/setiathome.berkeley.edu\MB_clFFTplan_GeForceGTX750Ti_524288_gr256_lr16_wg256_tw0_ls512_bn16_cw64_r3557.bin_36510, continue with recompile...
But the WU completed and validated with a copy of the previously listed command line.

More to check in the morning.......eyes starting to glaze over.

I am running 1 WU per GPU with 2 GPUs on the computer I am testing this on.

Thanks, I will give it a try. The computer I am testing this on is a dedicated cruncher, at present running `1 task per GPU.

I also have another dedicated cruncher running 2 tasks per GPU. The computers are very similar and I have never been able to actually figure out which is faster (more APR) as it seems to be so close.

OK, probably a basic question: Where do you put the command line and with what do you put it there?

I had a very similar problem 18 months ago and that turned out being a slow hard drive failure (it died about a week later).

Cheers.

Sounds like where I will try. I will do a mirror copy of the drive and then switch the current one out and see how that works out tomorrow.
Thanks

Why not just run the drive's manufacturer's diagnostic software on it 1st to see what it says?

Cheers.

You know, why didn't I think of that......the drive says it is fine.

I do not overclock.

Unfortunately, the overclocks aren't necessarily in the users control. The infamous GTX 560 Ti was factory overclocked and created and still creates an inordinate amount of invalids or inconclusives. I still chuckle when I look at some of my paired wingmen and discover the task was run on a 560 Ti. I had one of those myself at one time and am embarrassed to admit I ran it without realizing that out of the box, it could not compute accurately without some serious downclocking on my part.

You know you might be correct. The MB has autotuning and I have just turned that off to see what happens.
(I do have a SSD replacement drive on its way for tomorrow-I know that makes a difference on my laptop (but I only run CPU on it).

I will let you know how it works out.
