Hello,

I am a master degree student in MoSIG (Master of science in Informatics at Grenoble) in France, with specialization Parallel, Distributed and Embedded Systems (PDES).
I do my end-of-study internship at Atos/Bull in R&D HPC team about multikernel in HPC environment.
I study and tried your solution, IHK/McKernel, and have some questions.
I was able to use it on two socket Xeon platform. I'm trying now to use it on a KNL but have some difficulties.
I saw that the max number of threads is hard coded to 16. Why this limitation?
Also, with the Xeon platform, the output of lscpu is different with McKernel and Linux which is not the case with KNL.
I would appreciate to know if you are able to use IHK/McKernel with KNL, and if so, which modification are required.
Or do you have a development branch I could use for that purpose?

Thank you in advance for your answer.

Best regards.

Jérémie Finiel
