I'm not sure I understand the question.
The Linux kernel itself has no issues supporting 100's of CPUs (either
real, or SMT).
Not to be mean or anything....So please take it lightly:
Did I say linux has issues in supporting large smp? NO!
You are answering your own question. not mine.
As for application support, it greatly depends on the application
used. (E.g. Database, web-server, math, 3D, etc)
Did I say anything about application support? No!
Again, you are answering your own question.
I have found a few articles mentioning the smp granularity,
but do not discuss the linux smp implementation within the
context of granularity and overhead, and optimum degree
