Data partitioning

An important part to solving data parallel problems using multiple accelerators is to figure out how to partition data across the accelerators. The ALF API does not automatically partition data, however, it does provide a framework so that you can systematically partition the data.

1. Host data partitioning
   
2. Accelerator data partitioning
   When the data partition schemes are complex and require a lot of computing resources, it can be more efficient to generate the data transfer lists on the accelerators. This is especially useful if the host computing resources can be used for other work or if the host does not have enough computing resources to compute data transfer lists for all of its work blocks.
