Hello,
About Windows and processor groups..
Microsoft processor groups enable developers of multi-threaded applications to transcend the previous 64-thread restrictions.
For any system with more than 64 logical threads, Windows will evenly divide the threads into processor groups such that no group has more than 64 threads. On a dual-socket system with two 28-core CPUs and 112 total threads, for example, Windows will create two processor groups, each with 56 threads. On a single socket system with 64 cores and 128 threads, two processor groups will be created, each with 64 threads.
Windows defines the data structure for processor groups as a processor number, and within that structure is a data value called a group, and a group is a word data type, which is defined as a 16-bit unsigned integer. This means that one could have a maximum of 65,536 processor groups containing 64 threads each. So Microsoft Windows supports up to to 4,194,304 logical processors!
This is why i have implemented processor groups in many of my software projects, please look at my following website to notice it:

Even my Parallel Conjugate Gradient Linear System Solver Library that scales very well supports processor groups, here is my C++ version for Windows and Linux:

And here is my Delphi and Freepascal versions for Windows and Linux:

I won't trust software not being tested on a system it is designed for.
