Project Hogging both processor cores

Project Hogging both processor cores

I had 3 projects, WCG, SETI, and Climate prediction net. running on my dual core laptop.

WCG was running on both cores, but other projects were not working. I deleted WCG and now SETI is running on both cores but nothing is happening for climate prediction.

I've tried changing resource sharing options, but to no effect.

Can you help please?

Generally, you should see one running task per core.  ClimatePrediction had some bad workunits for a spell; maybe suspend that project temporarily, and see if this helps?

Hi Greg,

This behavior could be for a few reasons.

First the "debt" level of the projects are imballanced by a project or two having run less than the others.  This should balance out over time and needs no intervention.

Second if you are running a newer BOINC version (7+) the scheduling behavior has changed where projects are downloaded in batches and it is not uncommon for one project to use all cores then switch for another project to run all cores as batch processing allows.

Third yes the resource share could have caused a greater preference to one project to run more tasks at a time. 

What type of computer are you running (windows, mac, linux)?
