SMP

History and Status:

As of June, 2004, SMP (Symmetric MultiProcessor) support has been merged into the main OpenBSD development branch. At this time, the i386, amd64, mvme88k, sparc64 and macppc platforms supports SMP. The sgi port supports SMP on the multiprocessor Octane models, other machines are not yet supported. SMP support for the hppa port is nearing completion, however several bugs still exist which prevent it from running stably. Hopefully other platforms including sparc and alpha will ultimately support SMP.

Please see the appropriate platform page for SMP status for your system.

We plan to put up links to good documents here whenever we find them:
