Final week, we lined the AMD Intuition MI200 and the way AMD is claiming it gives a 4.9x speedup in some FP64 workloads over the NVIDIA A100. This week is Supercomputing 2021 and STH is on-site. We take a look on the AMD Intuition MI250X.

AMD’s sales space on the present seemed like many others. The area was nonetheless open with a number of chairs. As a substitute of the big show of EPYC and GPU methods, AMD had some printed banners within the background, branding for the ~3,000 attendees (SC19 was nearer to 14,000 for scale.) It appears as if the comparatively naked each with printing is widespread with many corporations that didn’t ship giant delegations as a result of pandemic.

What was completely different with AMD’s sales space is that they’d a HPE Cray EX235a node on full show. This node confirmed an AMD EPYC-based system with the brand new MI200 sequence GPUs/ accelerators. The node additionally had the HPE Slingshot interconnect.

HPE’s placard stated that that is the AMD Intuition MI250X so that’s what we’re tagging this as. There are the primary two compute dies every with 4 HBM stacks round them.

In AMD’s structure these have an interconnect between them so we now have two compute dies and eight of those HBM stacks on the package deal.

One can see the liquid cooling plates on the entire primary elements of the OAM GPUs. Additionally the PCBs for the Slingshot interface on the CPU aspect.

The tray has two CPUs every with 4 OAM accelerators from what we noticed.

Last Phrases

AMD/ HPE didn’t particularly disclose which EPYC CPU is on this node, so we have no idea whether it is Trento or one thing else. All we will see is that that is nonetheless an 8-channel reminiscence CPU (primarily based on the RAM coolers) and so it’s seemingly a Milan-era design.

There’s a not numerous {hardware} right here at SC21, so anticipate protection to be muted in comparison with a standard 12 months. Not having Dell, Lenovo, Intel, AMD (actually), NVIDIA, Arm and others right here is taking its toll. The businesses which can be right here have usually rather more sparse shows than a standard 12 months, so it’s exhausting to even discover numerous HPE/ Cray {hardware} despite the fact that HPE is right here.

Additionally as a fast one, I’m sending these pictures to Ian Cutress at AnandTech (he requested) so you might even see them over there in a bit as nicely.
