ULE scheduler paper
'SMT introduces a concept of non-uniform processors into ULE which
could be extended to support NUMA. The concept of expressing the
penalty for migration through the use of separate queues could be
further developed to include a local and global load-balancing
policy. At the time of this writing, however, FreeBSD does not
support any true NUMA capable machines and so this is left until such
time that it does.'
I am not sure about the meaning of 'true NUMA capable machines' but
AMD64 is ccNUMA unless I am completely mistaken, and FreeBSD/amd64 is
well-supported. Even multicore processors are available now and
Intel is going to release dual-core processors with HTT to make
Is there anybody working on this?
