A oneapi::tbb::scalable_memory_resource() is a function that returns a memory resource for scalable memory allocation.

The scalable_memory_resource() function returns the pointer to the memory resource managed by the oneTBB scalable memory allocator. In particular, its allocate method uses scalable_aligned_malloc(), and deallocate uses scalable_free(). The memory resources returned by this function compare equal.

std::pmr::polymorphic_allocator instantiated with oneapi::tbb::scalable_memory_resource() behaves like oneapi::tbb::scalable_allocator.
