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> Let us know if you need more help. |

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.
