-[[!meta title="Does GNU/Hurd support SMP/Multicore?"]]
-
-The Hurd servers themselves are multithreaded, so they should be able to take benefit of the parallelism brought by SMP/Multicore boxes. This has however never been tested yet because of the following.
-
-[[microkernel/Mach]] used to be running on SMP boxes like the [[!wikipedia
-Intel_iPSC/860]], so principally has the required infrastructure. It has
-however not yet been enhanced to support nowadays' SMP standards like ACPI,
-etc. Also, [[GNU Mach|microkernel/mach/gnumach]]'s Linux device driver glue
-code likely isn't SMP-safe. As this glue code layer is not used in the
-[[microkernel/mach/gnumach/ports/Xen]] port of GNU Mach, the plan is to try it
-in this enviroment first.
-
-[[!tag open_issue_gnumach open_issue_xen]]
-
-That is why for now GNU/Hurd will only use one logical processor (i.e. one core or one thread, depending on the socket type).
-
-Once this issue is solved, there are follow-up issues about
-[[open_issues/multiprocessing]] and [[open_issues/multithreading]].
