NUMA

NUMA

(Non-Uniform Memory Access) A multiprocessing architecture in which memory is separated into close and distant banks. NUMA is similar to SMP, in which multiple CPUs share a single memory. However, in SMP, all CPUs access a common memory at the same speed. In NUMA, memory on the same processor board as the CPU (local memory) is accessed faster than memory on other processor boards (shared memory), hence the "non-uniform" nomenclature. As a result, NUMA architecture scales much better to higher numbers of CPUs than SMP. "Cache coherent NUMA" means that caching is supported in the local system.
References in classic literature ?
Tarzan recognized the ear-marks of the witch-doctor and awaited Numa's charge with a feeling of pleasurable anticipation, for the ape-man had no love for witch-doctors; but in the instant that Numa did charge, the white man suddenly recalled that the lion had stolen his kill a few minutes before and that revenge is sweet.
The first intimation the black man had that he was in danger was the crash of twigs as Numa charged through the bushes into the game trail not twenty yards behind him.
Not an instant too soon did Tarzan reach the tree and swing himself into its branches and there he squatted, hurling insults at the king of beasts while Numa paced a circle beneath him, growling and roaring in rage.
They would have baffled an ordinary man; but the ape-man, accustomed to climbing, saw several places where he might gain a foothold, precarious possibly; but enough to give him reasonable assurance of escape if Numa would but betake himself to the far end of the gulch for a moment.
But even as he turned the matter over in his mind Numa turned suddenly and walked majestically toward the tunnel without even a backward glance.
Where the great apes are many Numa leaves us alone.
They had passed but a short distance to the rear of Numa when the boy caught the unpleasant odor of the carnivore.
As he trailed Akut he kept an eye cocked over one shoulder, rearward, in the hope that Numa might rise from his kill and reveal himself.
No ordinary man could have escaped those frightful claws when Numa sprang from so short a distance, but Tarzan was no ordinary man.
Here the ape-man unloosed his grass rope from about his neck, and as Numa stood above the body of the boar, challenging head erect, he dropped the sinuous noose about the maned neck, drawing the stout strands taut with a sudden jerk.
Quickly he made the rope fast to a stout branch, and as the panther, in answer to his summons, leaped into sight, Tarzan dropped to the earth beside the struggling and infuriated Numa, and with a long sharp knife sprang upon him at one side even as Sheeta did upon the other.
The panther tore and rent Numa upon the right, while the ape-man struck home with his stone knife upon the other, so that before the mighty clawing of the king of beasts had succeeded in parting the rope he hung quite dead and harmless in the noose.
