Research direction

Start by locating defer_temp_storage_destruction and the TODO about burying stream-provider memory before deallocation. Investigate whether sequential destruction kernels or a fused destructor kernel improves behavior, and define completion through measured evidence before changing the implementation.

Written by the indexing model from the issue text.

Description

cuda enhancement P2

Memory deallocation in defer_temp_storage_destruction might be blocking. We should investigate if launching all the destruction kernels in sequence (or fusing destructors in a single kernel) before releasing the memory is any better to address:

// TODO Bury all the memory associated with the stream provider and then 
//      deallocate the memory
