Flight and ground computing platforms contain multiple processing cores. Symmetric multiprocessing (SMP) support must be added to the OSAL to fully utilize these platforms.

Is this related to Steve Duran's techdev-osal-smp, [changeset:0437baa]?

Need a coordinated solution.

There's already the OS_EVENT concept implemented such that a PSP can do whatever is required at startup. Taking advantage of this an example was created to set thread CPU affinity: nasa/PSP#341

Could consider closing this. There isn't really additional requirements at the OS level... the PSP or a platform specific app could manage SMP. Removed the 'Draco' milestone since no other SMP work has been identified for closure this round.
