Sample of "AlgorithmsRadixSort" failed on OpenCL device

[GeoBIM2020]

The OpenCL device is 11th Gen Intel(R) Core i9-11980HK.

Following is error message:

Hi @GeoBIM2020, welcome to the ILGPU community. Thank you very much for raising this issue. Unfortunately, I'm not able to reproduce your issue at the moment. It may be an issue with an actual driver (version) being used. @MoFtZ maybe you have additional insights into this issue at the moment?

[MoFtZ]

@m4rs-mt I currently have access to a 10th Gen Intel Laptop CPU, and a 7th Gen Intel Desktop CPU, and have not been able to reproduce the problem either.

However, it is interesting that @GeoBIM2020 's CPU has MaxNumThreadsPerGroup: 8192. It is higher than I would expect, and I'm wondering if there is a driver issue, or if ILGPU is doing something wrong with OpenCL?

[m4rs-mt]

@MoFtZ I fully agree regarding the MaxNumThreadsPerGroup. In my opinion, this value should ideally fall within the range of [4, 128] (usually).

@m4rs-mt @MoFtZ There is no updated driver available for my CPU. Please let me know if you need me to do something.
