Hello, I wonder if there is a way to compute only on GPU. I have notebook which has not bad GPU. But its quadcore CPU get soon very hot (99 °C) so I want compute only on GPU which is ok. Is there a way? I know I can swith on GPU compute on preference on this site. But I have multiple notebooks and others do just fine even on CPU. So I want just this computer by only GPU and others not. But if I change preferences here on web.. it will affect all notebooks which I dont want.

Any idea? Thx a lot.

In your account
http://setiathome.berkeley.edu/prefs.php?subset=project
you will find SETI settings, remove the check by "use CPU".

That's what different 'venues' are for.

on your host page http://setiathome.berkeley.edu/hosts_user.php you can see an entry 'location'.
click on the 'details' link for the one host that you want to be different.
at the bottom of the page there is an entry 'location' select 'work' 'school' or 'home' - doesn't matter which, or if that computer is actually at such a location. click 'update'

in your host list 'location' for that host should have changed to the location you picked.

Now, go to project preferences http://setiathome.berkeley.edu/prefs.php?subset=project and click on 'add separate preferences for <location>' make sure to pick the extra location you just assigned the host to.

In THAT subset of preferences, untick CPU.

Isssue 'update' from the host in question to get it to see the new location and preferences.


In addition, Notebooks benefit from using 'TThrottle' for temperature controlled running - it allows you to specify a maximum temperature for CPU and GPU and it will thrittle the boinc threads so that that temperature is not exceeded. Do NOT use boinc's 'use only x% of CPU time'.

Most likely you want to assign that one notebook to a different location (also known as venue) than the other machines. If you go to your account page on the SETI website and then click on computers, then click on the details link next to the computer of interest, you'll find yourself looking at a generated page specific to that computer for which the very bottom line specifies the location. If the scroll box currently shows a dashed line, then that computer is currently set to the "default" location. Change it to something else, home, work, or school. Click the update button next to this choice, then navigate back up to your main account page, and click on the link for preferences for this project. You will find that page organized as four identical sections, one for each of the locations (also called venues). Click the edit link at the bottom of the listing for the location you have controlling your notebook of interest, and just un-click enabling of CPU.

I am not sure just how quickly this particular preference item takes effect. In general the preferences which affect choice of work to be downloaded stop new downloads but your computer finishes processing the ones which were already downloaded.

It would be probably worthwhile when you are done to check the computers page again and review particularly the "location" column. In this representation no characters at all means "default" instead of the dashes seen in the other place.

Good luck.

Easiest for me, I have 4 laptops crunching, is to use Lunatics installer and install GPU apps only. Additional work needed is to open the resulting app_info.xml file from ProgramData folder and replace all <count>1</count> with <count>0.5</count> in order to crunch two WU at a time.

Do that with an app_config file instead. The installer deliberately leaves app_config files intact, for that very reason.

(or does if I wrote it the way I remember writing it)

Thx a lot. It really solve my problem. So thx again. Notebook is now running only on GPU.

I am thinking about allowing 1 core also. I think venues can help with that too.

And I am sorry for such late respond while you help me almost instantly - it took some time for BOINC to accept new setting - so I want to be sure that your advise is fully functional.

Thx again;)

---

Well thx anyway;) I am really glad there at least two users here that want help :)

---

Yep, but this will affect all the computers. Other venues solve this particular problem.
