I've read a good deal of code involving lpl's but I'd like to clear a couple of ideas around it. If anyone could comment on these, I'd appreciate it.
(a) lpl's are used to determine the load average of lgroups, which is used by the dispatcher to load balance threads around (b) each lgrp has a lpl, which in turn may have leaf lpl's for each cpu in that lgrp (c) lpl topology is created by lgrp code (d) only leaf lpl's have CPUs (e) lpl's are the intersection of lgroups and CPU partitions I'm trying to understand where lpl's fir in the lgrp/cpus picture and what are their goal besides keep load averages (if any). thanks Rafael _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
