Hi, I read in the follow-up of the PR that current hard limit is 256. Currently available systems* can already push usage up to 240. IVB-EX aka Xeon E7v2 supports 8-socket * 15-core * 2-thread. Expect something to break 256 in less than a year I think. X2APIC support will be required then. In theory it is already possible to build larger systems with custom glue logic, but I am not aware of any. *: E.g. IBM System x3950 X6 -Jia-Shiun. _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
