<answer>
<para>Symmetric multi-processor (SMP) systems are generally
supported by &os;, although in some cases, BIOS or
motherboard bugs may generate some problems.</para>
<para>&os; will take advantage of HyperThreading (HTT)
support on &intel; CPUs that support this feature. A kernel
with the <literal>options SMP</literal> option, enabled
by default,
will automatically detect the additional logical
processors.</para>
<para>&os; supports Symmetric multi-processor (SMP) on all
non-embedded platforms (e.g, i386, amd64/x86-64,
ia64, sparc64, powerpc, powerpc64). SMP is also
supported in arm and MIPS kernels, although some CPUs
may not support this. &os;'s SMP implementation uses
fine-grained locking, and performance scales nearly
liniarly with number of CPUs.</para>
<para>&man.smp.4; has more details.</para>
