No, normally, BOINC will run a WU for each core you have. You can limit how much of each CPU gets used so you may want to confirm that you have that at 100 percent. That's the "On multiprocessor systems, use at most" and the "Use at most" values that you can see by clicking on Tools|Computing Preferences|Processor Usage in BOINC Manager. You can change those values there for just that machine or for all of your machines by going to your BOINC profile on the WCG website. As for "speeding up" processing of that WU, stoppping any other active tasks on that machine (browsing, game playing, etc.) will avoid taking away CPU resources that that WU could use.

Doppelbock, Welcome to the forums. Some processors utilize multithreading where each core is used as two virtual cores or threads. In doing so, each thread shares the same core for processing and therefore will take more time to process each workunit than if the core was used for just one workunit. Turning off multithreading in the Bios will cause the workunits that are running to complete faster. A simpler solution would be to just suspend all workunits other than the one you want to finish and it should finish faster. The speed increase will not double but will be faster. Some crunchers run with multithreading always tuned off for this reason. Keep in mind that this only works for multithreading CPUs like the Intel i7s.

Hi guys,

Sorry to drop in at the end of thread, but I was wondering if Delta, KWSN, or Keith have noticed if it work units that work with HT turned off do over all more task units because they finish them faster or if it is still better to have HT turned on in the long term.

Thanks

Would the computer or at least the cpu run half as hot with HT turned off?
Or would it only be about 15% cooler?

I have an older computer, one core cpu, that runs 2 cores while in Hyperthreading
