So, I'm currently having an issue with seti on my new system. If I let seti use 100% CPU, my GPU hardly does any load, roughly 12-15%. I can also tell that it's not doing as much work, as the project the GPU is working on crawls along really slowly.

Now, if I throttle the CPU down to 1%, the GPU happily sits around 81% usage, sometimes goes near 90%. This is all good and well. But once I start upping the CPU allowance, it all goes downhill from there.

I've spent more time than I would like trying to find a useful configuration to fix this issue. I would like to run just 1 WU at a time, and have the CPU and GPU process the same WU until it is done. Right now, it's processing 8 WU's at a time, and with my 1% CPU throttling, it's going to take days to finish :(

If anyone could help me with a config to load into BOINC, I would love you forever.

I tried using this config, but it didn't seem to work.

<app>
<name>setiathome</name>
<max_concurrent>1</max_concurrent>
<gpu_versions>
<gpu_usage>1.0</gpu_usage>
<cpu_usage>1.0</cpu_usage>
</gpu_versions>
</app>
</app_config>

Any tips from the config pros?

Oh, and I have no idea why it says I'm administrator. *Shrug* I created this account back in 2006.

In Boinc manager settings choose on multiprocessors use only 84% of CPU.
This reserves 2 CPU cores.
Works fine with my FX 8150 and HD 7970.



With each crime and every kindness we birth our future.

Have a look at it now, MUCH MUCH MUCH better.



Hats off sir, you've just made my day.

To change the "administrator", you need to go to the account page, then go to other account informations (not sure is that is the name because i use a portugues version - located in the same line where you change you e-mail adrress) and then change your nick name as you wish.

Anytime. Just a tip, your GPU could easely run more than 1 WU at a time, check with Mike the best configuration to do that (he uses ATI like you) and don´t forget, it´s a good practice to increase the fan speed when you crunch with the GPU´s they will run hotter than normal.

That's because that is set up wrong, for Seti v6 the name is <name>setiathome_enhanced</name> for v7 it's <name>setiathome_v7</name>

it's also missing the opening tag, try the following (you can remove the <max_concurrent> line if you wish):

<app_config>
<app>
<name>setiathome_v7</name>
<max_concurrent>8</max_concurrent>
<gpu_versions>
<gpu_usage>1.0</gpu_usage>
<cpu_usage>1.0</cpu_usage>
</gpu_versions>
</app>
</app_config>
