Hi folks,

I have a question about optimizing Seti for my GTX1080. I read that you can configure commandline code to accelerate the crunching. I need about 5 minutes for an SoG workunit right now.

I found this in the thread about the Radeon VII
-sbs 2048 -period_iterations_num 10 -high_perf -spike_fft_thresh 4096 -tune 1 64 1 4 -oclfft_tune_gr 256 -oclfft_tune_lr 16 -oclfft_tune_wg 256 -oclfft_tune_ls 512 -oclfft_tune_bn 64 -oclfft_tune_cw 64 -cpu_lock

I have no clue what this does and how to read this line of code. Is there a possibility to use it for my GTX1080 or do I have to adapt it for Nvidia? And if so, how do I do that?

Thank you very much!

Mike is the go to guy for the command lines but you can use that. Not sure if you need the cpu_lock. Might want to add -hp and decrease the -period_iteratons_number to 1. Beaware that this will cause your system to lag and screen too as it's going to devote alot of resources to the GPU task. If you don't want that. Then don't add the -hp and move period_int_nu to 30. I thought there was a -tt somewhere in there?? Been so long since I ran the SoG.

Edit...

Found it

-sbs 1024 -period_iterations_num 1 -high_perf -hp -high_prec_timer -tt 1500

This is what I used to run for SoG. Not sure but I think -high_prec_timer isn't needed. I'd wait and see what Mike has to say.

This is what I ran on my GTX 1070/1080's when I ran SoG.

-sbs 1024 -period_iterations_num 1 -tt 1500 -high_perf -high_prec_timer -spike_fft_thresh 4096 -tune 1 64 1 4 -oclfft_tune_gr 256 -oclfft_tune_lr 16 -oclfft_tune_wg 256 -oclfft_tune_ls 512 -oclfft_tune_bn 64 -oclfft_tune_cw 64

Thanks Keith, that works on My Asus 970 Turbo.

If the keyboard/screen is too lagy but you want to push it that hard when you are not logged into the machine you can set the local/website? parameter to suspend the gpu when you are "active."

While the parameters should make a difference I would be surprised if they cut your processing time in half.

You may be able to raise your total production by running 2-3 SOG gpu tasks at the same time. It will slow the average processing time down but your total production would go up. The trick is in your "app_config.xml" file in your "ProgramData\BOINC\projects\setiathome.berkley.edu\" sub-directory (it's hidden, so you need to toggle your view settings in Windows).
If your average processing time more than doubles for two tasks, then its not a good idea to run multiple gpu tasks.

<app_config>
<app>
<name>setiathome_v8</name>
<gpu_versions>
<gpu_usage>0.5</gpu_usage>
<cpu_usage>1.0</cpu_usage>
</gpu_versions>
</app>
<app>
<name>astropulse_v7</name>
<gpu_versions>
<gpu_usage>0.50</gpu_usage>
<cpu_usage>2.0</cpu_usage>
</gpu_versions>
</app>
</app_config>


<project_max_concurrent>36</project_max_concurrent>

The 0.5 per gpu will run 2 tasks at the same time. 0.3 will run three.

You have not contacted the Seti server since March 3. Hope nothing is wrong.

Hi Tom,

thanks for asking. No, everything is fine. I just wasn't at home and will restart with crunching Seti, soon. Thank you all for your help! Very much appreciated. I'll try the configs above and let you know how it went.
