The threading efficiency goes down slightly with the number of cores I guess. With my C2D E6600, the CPU utilization stays pegged at 100% during most of the run.
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 coresI 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.
