I have an 11.0-RELEASE-p1 system with: hw.model: Intel(R) Xeon Phi(TM) CPU 7250 @ 1.40GHz It's got 68 cores, but with 4-way SMT, I think it should show up with 272 logical cores on FreeBSD. However, in both kern.sched.topology_spec and hw.ncpu, it shows there are only 223 cores. Is the limit effectively 223 cores, even though I see some #define MAXCPU 256 lines in the source? - Eric
