Add an allocator to TensorOperationsAlgorithm#212
Merged
Conversation
Adds an `allocator` field to `TensorOperationsAlgorithm` alongside `backend`, so a caller can choose the allocator for a contraction (e.g. `TensorOperations.ManualAllocator()`, or a Bumper buffer), not just the backend. It defaults to `DefaultAllocator()`, so the default path is unchanged.
Only construct `DefaultBackend()`/`DefaultAllocator()` when the corresponding field is `nothing`.

Checks that a `TensorOperationsAlgorithm` with an explicit allocator, the `ContractAlgorithm(backend, allocator)` seam, and the `nothing` defaults all match the default contraction, out-of-place and in-place, across real and complex element types.
