German Andryeyev developed a new HIP runtime API attribute for the ROCm/hip repository, enabling users to query the number of XCCs present on a device. By extending the existing enum in the HIP header, he introduced hipDeviceAttributeNumberOfXccs, which allows for more accurate device capability queries and supports improved workload partitioning on multi-XCC GPUs. His work focused on low-level programming and hardware abstraction using C, resulting in a minimal API surface change that simplifies adoption by downstream tools and libraries. This targeted feature enhanced device introspection and resource allocation, reflecting a focused and technically sound engineering contribution.
