Has anyone done any research on what I called 'NUPA' -- NUMA for processors, basically ??
This is probably a totally crazy idea, but I was wondering how possible it would be for Linux to seamlessly support, say, a PowerPC Mac or Sun with an x86 accelerator card. Or, to get even crazier, offload some processing onto a GeForce or one of those video cards with dual Rage128 chips.
If 'NUPA' support existed, it seems like a prerequisite would be eliminating many of the scaling problems typically associated with OS<->hardware SMP interaction. ie. creating spinlocks useable by only a small portion of the available processors in the system. and that's only the tip of the iceberg.
