I'm running Seti@Home and Einstein@Home have have allocated the CPU resources equally @ 50%. How does the software allocate priority? Does each project share CPU time by one project running the fist half hour and the second project running the second half hour?

Please explain...

Thanks!

This can get a bit complex.

1) The default time between switches is one hour.
2) In Round Robin mode, you are correct it normally switches once per period.
3) There is also Earliest Deadline First that is used when there is work on the host that may have difficulty meeting deadline in RR mode.
4) In RR mode the next project to get work is controlled by the Short Term Debt (a bit of a misnomer). The project with the highest debt gets to run now. While a project is running, its STD normally drops.
5) The same rules apply to multi CPU systems, but they can be running any mix up to N CPUs.
