Line 39:
An task may have some inherent randomness, with alternative solutions for handling this either through reads or writes, with scatter or gather alternatives. These choices appear in GPGPU and graphics applications:-
==== sequential reads with scatter writes ====
The scatter approach may place less load on a cache hierarchy since a [[processing element]] may dispatch writes in a 'fire and forget' manner (bypassing a cache altogether), whilst using predicatble prefetching (or even DMA) for it's source data. However, it may be harder to parallelise since there is no guarantee the writes do not interact.
