Hi,

Currently my two video cards are hammering away on cuda tasks, but is there a way to get my CPU working on SETI as well? Seems a waste to have it just sitting there idle

I'm not really interested in any other projects you see

thanks

But the CPU is working on SETI - you have reported completed CPU tasks (SETI@home Enhanced v6.03) on 14 May 2012 | 12:31:14 UTC

I think that's my core i5 machine, not the i7

The i7 (midianx6) doesn't appear to be doing CPU WUs

The Intel(R) Core(TM) i7-3930K CPU @ 3.20GHz machine is ID: 6651066

Look the link again:
http://setiathome.berkeley.edu/results.php?hostid=6651066&offset=20&show_names=0&state=2&appid=

(since you say "cuda tasks" I looked at the Computer with CUDA GPU (NVIDIA GeForce GTX 670) and this is the i7-3930K machine)

(and of course no one except you can see the names like "midianx6", always refer to your Computers here by ID number, not name)

Ah i see thanks BilBG

Strange that when i look on BOINC, it only shows CUDA tasks working, and no CPU tasks (none even downloaded)

Also my cpu usage is very low indeed.

I've not checked since before i left for work, but hope that you're right!

I wasn't sure if it was possible to run CPU and GPU together

Maybe not enough tasks are downloaded so the CPU have work only from time to time.

Try to increase this (the default is maybe 0.2 days?):
Maintain enough tasks to keep busy for at least 3 days
http://setiathome.berkeley.edu/prefs.php?subset=global


To check that the Computer is/was working on CPU tasks (SETI@home Enhanced v6.03)

In BOINC Manager hit Ctrl+Shift+E
[Copy all messages]
Paste them to/in Notepad
Search for string:
using setiathome_enhanced version 603

(the full log for months back is in the files stdoutdae.txt and stdoutdae.old)

May as well ask since i'm here, is there an advanced app you would recommend for my CPU - supporting new instructions etc?

I've been out of the game for a while!

Yes:

Subscribe to this thread to know the news about "Optimized Applications"
http://setiathome.berkeley.edu/forum_thread.php?id=53611&nowrap=true#1210312

Read:
http://setiathome.berkeley.edu/forum_thread.php?id=67407

You need "Installer v0.40 64 bit" (for more info read "Installer v0.40 Readme"):
http://lunatics.kwsn.net/index.php?module=Downloads;catd=9


The process is just to exit BOINC, run the Installer, choose the apps:

(!!! Choose all the apps that you need (e.g. also CUDA)
- you can't use Optimized app for CPU + standard for GPU, choose both in the Installer.
If you forget to select CUDA - your current CUDA tasks will be deleted and no more CUDA tasks will be downloaded.
)




Pros:
150-200% faster CPU processing
Less errors on CUDA (+ small ~5-10% better speed)
You can run 2 or more CUDA tasks simultaneously on every of your 2 GPUs (by manual edit of one file)
(your GeForce GTX 670 is capable of maybe 3 tasks (= 6 total running for your 2 GPUs))

Cons:
No graphics/screensaver
You will have to check here from time to time when new apps are released to change them (by new Installer) - unlike the standard apps they will not be updated automatically.
