Awesome work! Look forward to trying it out.

Is this correct?
e.g.: CHIP0 has cores 0,1,2,8,9,10 and so does CHIP1,
but there is no core labelled 3,4,5,6,7 and 11
also the cpu numbering seems 'staggered' to me -
e.g. chip0/core0/{cpu1,cpu13) and chip1/core0/{cpu0,cpu12}
rather than something more like:
chip0/core0-5/cpu0-11 & chip1/core6-11/cpu12-23
Disclaimer: haven't read the code, etc - just thought I'd ask esp.
since the benchmarks around the same time as you sent this mail
seemed to show inconclusive results - perhaps discovery issues are
translating to problems in the scheduler or something.
2c from the peanut gallery
Good luck & continued success!
Cheers,
