Closes #4333
For reviewers:
Many of changes are simple textual replace of
rmm::mr::device_memory_resource *
withrmm::device_async_resource_ref
.However, I found that
concurrent_unordered_map
used in cuGraph is not up to date with thelatest changes from the version in libcudf, so I copied those over as well. This gets rid
of the
hash_allocator.cuh
, and usesrmm::mr::polymorphic_allocator
instead of the customallocator previously used. This obviates the need to update any
device_memory_resource*
usedin the old custom allocator.
