<a name="l1"></a><span class=cF0>ZealOS does master-slave multicore instead of SMP. </span><span class=cF2>Core0</span><span class=cF0> is the master. The master core's applications explicitly assign
<a name="l2"></a>computational jobs to other cores and the ZealOS scheduler does not move tasks between cores.
<a name="l3"></a>
<a name="l4"></a>There are multicore safe locks for file access and heap allocations, however, so ZealOS is symmetrical in some sense. See </span><span class=cF4>

<a name="l7"></a>Only tasks on </span><span class=cF2>Core0</span><span class=cF0> can have windows, but other cores can help render them.
