Scope and uncertainty
Microsoft publishes no virtual-machine specification for the ND96_amsr_MI200_v4 size named in the TOP500 submission; the documented ND family covers the NVIDIA A100, H100, H200, GB200 and AMD MI300X sizes only. Per-node memory, accelerator count and node count are therefore unavailable rather than merely unlocated.
Documented fields: 7 / 27
Every field this catalog checks. Fields listed above have a value; the remainder are shown here. A field marked absent is not publicly available in the sources we could verify, which does not mean the hardware is missing. Fields that cannot apply, such as benchmark results for an unranked system, are excluded from the total.
