CaddyLappy1,

for the moment u can do 2 things....@ WCG's BOINC device profile, set 1 processor...it will use 100% of 1 core, it will read in the taskmanager as overall 50%. If u want to do 2 simultaneous but at less than 100%, u can be patient until BOINC introduces the throttle function which is in some undefined schedule (at least not read anything definitive), or look up the Threadmaster Success Stories posts on this forum....works for me. By changing a percent in the registry, the next WU for the particular science will pick up to new desired value....no need to stop, boot or anything.

Each core will only do 1 WU. U cannot force a particular core to do 2 WU and the other reserved for anything else.....it's more efficient to set Threadmaster to do 50% for each science and use the spare power for whatever. If u said, use core 2, and reserve core 1 ....someone else may know how to do that.

Yes.
1) You can go into task manager (ctrl+alt+del)
2) Find the WU process, and right click on it.
3) In the menu, select "processor affinity" - the last option.
4) This will allow you to see and change which core the process runs on - CPU 0, CPU 1, or both. (The number of cores start from 0, so it really is core 1 and core 2.)
5) Uncheck the core you want to reserve for your own usage and click OK.
6) Repeat this with any other work unit process running.
7) All the WU processes will run purely on the core(s) you selected, so in my case:

Core 1: 0% usage
Core 2: 50% usage for one WU, 50% usage for the other WU.

Because the second core is fully loaded, the system will make everything else run on the idle core, and that includes browsing, games etc.

This is a good way or running WUs while playing games without performance detriment, because unlike popular opinion, even if the WU is set to idle priority, it will still result in mometarily lower performance for a game which wants to use the core.

ok thank you i will try that - does this mean however that for each new unit i have to affiliate the unit to core 2 again ? i have tried it with the wcg client but on each new unit i had to re assign the core

thanks all for the replies and info

Learning every day.......just a word of caution....make sure to read up on having 2 BOINC WU's process on 1 core.....they may interfere with each other causing results to be deemed invalid or with error.
