This is actually more than what the title says, but if I included all my questions in the title, it would be silly long.

Question 1: How do I limit myself exclusively to AstroPulse?

Question 2: How do I limit the number of tasks running at one time (say, one or two... running 5 at once at a processor usage limit makes it take too long).

Any help will be greeted with great fanfare and enthusiasm.

Another Question: I set my preferences to exclusively AP, but the times to completion look really close, so if I turn my computer off at all, it will not be completed, which bugs me. Where do I reverse my lunacy?

The estimates for time to completion are likely to be too large for AP.

You can reverse your decision at the same place that you made it in the first place.

I believe that you have already figured this one out on your own


Question 2: How do I limit the number of tasks running at one time (say, one or two... running 5 at once at a processor usage limit makes it take too long).
AP is a single threaded process (it can only use one CPU or CUDA device). You are running one task for each CPU and CUDA device on your system. Reducing the number of tasks running will not affect the duration of the other tasks very much. However, in the "Your account" area there is a section for "Computeing Preferences". Under this you will find settings for Max % of CPUs to use, and Max # of CPUs to use. Set the one that is appropriate for the version that you are using. The other way of doing this is on the advanced menu item of the advanced tab of the BOINC Manager UI. This second method is a local override for the Web setting.



Any help will be greeted with great fanfare and enthusiasm.

AP can run on CUDA these days?

Oh foo, not yet. It is being worked on.
