Single thread section loads ALL cores 25% each. I can change this by setting affinity obviously.

Also, there's a problem with it. If you cancel it early then it takes that time as your benchmark time.

When in the single thread section, the OS does the division of work... so to optimize your score, set the affinity :P

If you cancel prematurely, the score appears with a brown under line and will reflect the same when saved to the hard drive (did you try that feature btw :P)

Nice score.... I am using "Coarse multi threading" instead of fine grained multithreading using a combination of primality algorithms ATM. The particular algorithm which is used is decided based on the "hugeness" of the number in question. And then some trickery to keep all the cores loaded to the hilt at all times

Thanks for the screen shot mate

So it is indeed loading all the cores I wish there was someone with > 8 cores in XS so I could test it at greater than 8 threads

A new version, 0.9.7 is coming out momentarily with updates to read cache information from AMD cpus.
