like to know how to config boinc to be able to use 8 cpu's for 1 seti task, me what i prefer is to make the process faster for 1 task not use all 8 cpu for 8 task's

The current CPU applications are not designed to run across multiple CPU cores or threads. It would probably take a substantial amount of re-working to get the required synchronization functioning correctly. From experience with other multi-threaded applications it is is highly probable that an n-threaded SETI application would actually deliver less work per hour than running n-single thread applications.

There is of course nothing stopping you obtaining the source code and spending the required time and effort to get such an application running in a stable and accurate manner.

i search for a way to use my gpu to calculate 2 seti task at the same time but can't seem to find a right app_config.xml or cc_config.xml to use properly. Some people say to do this other say to do that, can't seem to find the right answer. Can you help...

<app_config>
<app>
<name>astropulse_v7</name>
<gpu_versions>
<gpu_usage>0.5</gpu_usage>
<cpu_usage>0.04</cpu_usage>
</gpu_versions>
</app>
<app>
<name>setiathome_v8</name>
<gpu_versions>
<gpu_usage>0.5</gpu_usage>
<cpu_usage>0.04</cpu_usage>
</gpu_versions>
</app>
</app_config>

<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>

1 x NVIDIA GeForce GTX 650 ti Boost

it take 18 min to do seti@home_v8 and 56 min do to astropulse_v7

I don't think you will find a performance gain from running 2 tasks on that card, most people with 750Ti cards only run 1 task, with an aggressive command line. I don't think you have a command line in use.

If you do run 2 tasks the app_config.xml goes in the SETI folder, the cc_config in the BOINC folder.
You should also have <cpu_usage>1.0</cpu_usage> for the SoG application. It needs a full thread to work properly.

thank's all work fine for gpu task instead of taking 18 min for 1 task it take 23 min for 2 task (2 x 23 min at the same time) for Seti. I'm will test this for a week and see if i get good result. I also using TThrottle so that nothing burn :)

The big thing with 2 vs 1 tasks is you need 2 CPU threads as well, so you are wasting one.

thank's all work fine for gpu task instead of taking 18 min for 1 task it take 23 min for 2 task (2 x 23 min at the same time) for Seti.

Looking at several of your Validated WUs it's more like 37 min. My GTX 750Tis are taking around 13min. I'll stick with one at a time.
