Question about multiple core computing

If there is a 4-core computer, but only 2 tasks on BOINC, does that mean 4 cores will contribute to these task together? or two of those are working and another two cores are suspanded? confused

Re: Question about multiple core computing

Hi yrr933, welcome to the fora!

Each (CPU-based) BOINC Work Unit uses a single execution thread. So, if you have a 4-core 4-thread machine with two BOINC WUs running, then two threads will use all their spare capacity on running those WUs, and the other two threads will only be running whatever else is running on your machine -- they will not be able to process any BOINC work.

Hope that helps.

Re: Question about multiple core computing

Depends. If it is a hyperthreaded type CPU, tasks could be with a 2 thread setup running in as much as under 60-70% of an 4 thread configured client. Depends of course what the non-BOINC loads are.
