hardware SKILL.md skillA
hardware from amd-agi/hyperloom is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add amd-agi/hyperloom/hardware@git:20261105.0d95dc2Pins git:20261105.0d95dc2 in mdr.lock. Pin the fingerprint instead.

AMD Instinct hardware facts for kernel authoring, rooflines and communication — MI350X/MI355X (gfx950, CDNA4) and MI300X/MI325X (gfx942, CDNA3) — with the spec peaks, how to measure what a node achieves, the memory hierarchy, LDS banks, MFMA and block-scaled matrix instructions, the gfx950 ISA additions, XGMI/collective bandwidth, and where each fact comes from. Use when writing or tuning a kernel, pricing a direction against its floor, writing a kernel plan, reading a roofline, or deciding…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Hardware: AMD Instinct for kernel authors The facts a campaign needs when it prices a direction, writes a kernel plan or reads a roofline. `reference/` holds the detail. It is KernelForge's hardware knowledge base (`local_knowledge/hardware/`, AMD, MIT licence: `reference/LICENSE-KernelForge`), imported unchanged on 2026-10-20. KernelForge's separate gfx950 summary (`knowledge_base/shared/gpu_arch_gfx950.md`) was not imported: it says "304 CUs", "32 banks" and "similar to MI300X's 5.3 TB/s", all wrong for gfx950. ## The quick facts | | MI350X / MI355X (gfx950, CDNA4) | MI300X (gfx942, CDNA3) | MI325X (gfx942) | | --- | --- | --- | --- | | CUs | **256** (8 XCDs × 32) | 304 (8 × 38) | 304 | | Wavefront, SIMDs/CU | wave64, 4 | wave64, 4 | wave64, 4 | | VGPR / AGPR | 512 × 4 B per SIMD / ≤256 | same | same | | LDS | **160 KiB/CU, 64 banks, 256 B/clk** | 64 KiB, 32 banks, 128 B/clk | as MI300X | | Direct global→LDS | up to 128 b/lane (`global_load_lds_dwordx4`) | 32 b/lane | as MI300X | | L2 | 4 MB per XCD (not device-wide), 16-way | 4 MiB per XCD | as MI300X | | Infinity Cache | 256 MiB, device-shared | 256 MiB | 256 MiB | …

How to install
mdr add amd-agi/hyperloom/hardware@sha256:342dc14a19b7a594The line at the top of this page pins the label git:20261105.0d95dc2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
