Detailed Description

Annotate the region where the buffer need to be read and write in the body. We only need to allocate the space for the corresponding region.

Note

There should be at most one BufferRealize for each buffer. BufferRealize is not necessary for external buffers, since they are assumed to be fully allocated.
