Thats reasonably accurate, we're fusing both pre-defined operations as well as codegenned operations. Block-level operations live inside the search space, as do kernel, warp and thread level operations. Since it's a unified search space, we can look through tons of combinations of kernel, block, warp, and thread level ops. When we go to compile them to runnable code, thread ops get compiled to warp ops, warp ops get compiled to block ops, block ops get compiled to kernel ops (megakernels live here!), so at the end of the day everything that gets ran is a kernel.

In other words, very complimentary to our search-based approach.
