A method, apparatus, and program product retrieve data for a task utilizing demand-based direct memory access ('DMA') requests.

The method further comprises, in response to determining that the first DMA request is not complete, determining whether to proactively analyze a second portion of the task prior to the execution thereof for a determination whether data required for execution thereby is stored in the local memory.
