Writing Parallel software Task parallelism Concept parallelism achieved through the partition of load into "baskets of work" consumed by a pool of resources. Implications o requires splitting the processing into blocks o and dealing with dependencies between them o well adapted to data processing frameworks Thread/process pools usually useful a pool a workers is created at start o and reused during all processing tasks are mapped to available workers what find expect 8/46 S.Ponce-CERNWriting Parallel software 8 / 46 S.
