Message 1862303 - Posted: 19 Apr 2017, 4:53:05 UTC

Hello,

I copied the below text from another thread (switching the 7 to an 8 in SETI@Home), and now I have two GPU WU's but they are not progressing. I also Dropped the CPU cores used to 90% to free up one thread to manage these work units.

Any help here? Information is fragmented about this subject and it hasn't been talked about at length since 2015 from what I can tell (hence my change to the version number), and I'm sure there is something else I need to do that I'm not.

<app_config>
<app>
<name>setiathome_v7</name>
<gpu_versions>
<gpu_usage>0.50</gpu_usage>
<cpu_usage>0.50</cpu_usage>
</gpu_versions>
</app>

<app>
<name>astropulse_v7</name>
<gpu_versions>
<gpu_usage>0.50</gpu_usage>
<cpu_usage>0.50</cpu_usage>
</gpu_versions>
</app>
</app_config>

You say you are changing from 7 to 8. What apps are you wanting to run? SoG is the preferred at the moment but you can run cuda 5.0 This app_config is set up for SoG. SoG is faster than cuda unfortunately, it requires 1 core of the cpu for each work unit. If you don't want to do that, you can install a commandline with -use_sleep that should cut down the CPU usage. I'll post both here for you. The server will send you the latest app but if you want there is a beta installer of lunatics 6 out there.

<app_config>
  <app_version>
    <app_name>setiathome_v8</app_name>
    <plan_class>opencl_nvidia_SoG</plan_class>
    <avg_ncpus>1</avg_ncpus>
    <ngpus>0.5</ngpus>
  </app_version>
   <app_version>
    <app_name>astropulse_v7</app_name>
    <plan_class>opencl_nvidia_100</plan_class>
    <avg_ncpus>1</avg_ncpus>
    <ngpus>0.5</ngpus>
  </app_version>
</app_config>


app_config with commandlines

<app_config>
  <app_version>
    <app_name>setiathome_v8</app_name>
    <plan_class>opencl_nvidia_SoG</plan_class>
    <avg_ncpus>1</avg_ncpus>
    <ngpus>0.5</ngpus>
    <cmdline>-use_sleep</cmdline>
  </app_version>
   <app_version>
    <app_name>astropulse_v7</app_name>
    <plan_class>opencl_nvidia_100</plan_class>
    <avg_ncpus>1</avg_ncpus>
    <ngpus>0.5</ngpus>
    <cmdline> </cmdline>
  </app_version>
</app_config>

I am not certain here but unless you are actually getting Seti at Home version 7 applications, your app_config.xml file may not be talking to your V8 seti applications?

You may want to change those to:

<app>
<name>setiathome_v8</name>
<gpu_versions>
<gpu_usage>0.50</gpu_usage>
<cpu_usage>0.50</cpu_usage>
</gpu_versions>
</app>



You might take a look at your windows 10 task manager and see if it is displaying 2 SOG applications with steady loads of perhaps 25%? If isn't doing that then maybe you need to tinker with your mb*SoG.txt file?

-sbs 192 -spike_fft_thresh 2048 -tune 1 64 1 4 -hp


Might help.
