What happened and what to do
Published on April 6, 2026, the post says that 64-bit pointers allow buffer access without fetching a descriptor from the descriptor heap. It cites this approach in CUDA and Metal, as well as Vulkan BDA in GLSL, and states that DX12 does not support pointers. Its focus is comparing buffer access models across GPU APIs.
A company running GPU workloads could map the APIs it uses, compare their access models, and test the impact on its own workloads. It could then document limitations and inform architecture and portability decisions, without assuming one approach suits every environment.
How the consultancy can help
Wendelmaques can assess the relevant APIs and workloads, evaluate portability and performance requirements, and propose a scoped implementation of tests, monitoring, and technical documentation. It can also support operation of the chosen solution.
