+[[!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]].
