Detailed Description

Copy launchers are objects that can be used to issue copies between two regions including regions that are not of the same region tree. Copy operations specify an arbitrary number of pairs of source and destination region requirements. The source region requirements must be READ_ONLY, while the destination requirements must be either READ_WRITE, WRITE_ONLY, or REDUCE with a reduction function. While the regions in a source and a destination pair do not have to be in the same region tree, one of the following two conditions must hold:

1. The two regions share an index space tree and the source region's index space is an ancestor of the destination region's index space.
2. The source and destination index spaces must be of the same kind (either dimensions match or number of elements match in the element mask) and the source region's index space must dominate the destination region's index space. If either of these two conditions does not hold then the runtime will issue an error.
