Message 89380 - Posted: 22 Mar 2005, 23:47:47 UTC

Hi, im sort of new to Boinc but it seems like the new version .25 or w/e is choking my computing, because in the status window for work its only showing 1 of the two prjects i joined as being worked on, is there any way to change this? or is that a feature im just not understanding...
thanks for any help,

Unless you run HT or have dual CPUs, the projects will switch with each other (default is 60 min) based on the resource allocation.

BOINC only runs one project at a time. It will switch between them every 60 minutes (by default - you can change it). So for 60 minutes it will work on only seti and then it will work on the other project for 60 minutes and then switch back to seti. This is also subject to change based on the resource share you have allocated to each project but that is the general idea.

Looks like Randy is a faster typer than me! :)

So is that more efficient than the way it was doing it in the previous version ? (i guess that was continual switching back and forth) Thanks for the answers too.

Basically the rule is "one work unit per CPU at one time". I have hyperthreading so my computer appears to have two CPUs from BOINC's standpoint. This was actually a problem when I only had .1 day's work cached, as only one work unit would be on hand. CPU usage stayed nailed at 50% until I started caching multiple WUs, when it could process two concurrently.

By the way, I experimented with turning hyperthreading off, but that caused no end of other problems with my system.

Yes, it is.
