Still need help? Both of these preference changes were applied to the 'work' venue and this venue is used only by the MacPro3,1. Am I mistaken, or does it take a while for this preference change to have an effect?

The change applies to new tasks that are sent to you. I'm not actually sure if old tasks already in your cache have to be cleared first or whether you just have to download new work for the change to apply. I thought you had to finish the cached tasks as singles and then the new tasks would be done as doubles but I did see a recent comment that old tasks could be done as doubles once the setting change had been communicated to the client through the arrival of new work.

I don't know whether that is correct or not. I have both read such comments and actually observed such behavior on my host, I believe. So it can take quite a while for the change to be effective, or it can be quite rapid. Thanks, Gary and archae86, for the illuminating comments. The run-time for these BRP tasks is in the range of 3. At this point, because of the fact that this machine does work for four different BOINC projects and has been doing a fair amount of "real" work , it is difficult to say at this point whether the improvement in processing the BRP tasks is greater than the loss of productivity caused by dedicating one of my CPU cores.

I'll continue to monitor this machine's productivity and will post a followup.

Thanks for advising me that I may need to clear the cache of BRP tasks present at the time of changing the E H preferences before I experience the full effects of the changing those preferences. Will post an update after that cache is cleared.

Alas, I am still only processing one GPU task at a time. However, the decreased processing time for these tasks appears to balanced out the loss of one of my CPU cores.
