Adrian Jackson @adrianjhpc.bsky.social · 01/09/2026We report cost, accuracy, performance (both user experience and system output), and energy estimates. Accuracy confirms run validity and can reveal the available trade-offs between all these metrics. 110
Adrian Jackson @adrianjhpc.bsky.social · 01/09/2026The benchmark uses each dataset's natural lengths. That means we have to handle chunked prefill, refusals, and steps that mix prefill with decode. This avoids the distorting effects of fixed-length measurements and allows us to capture real sparse activations and bandwidth utilisation. 100
Adrian Jackson @adrianjhpc.bsky.social · 01/09/2026Current results cover NVIDIA A100, H100, H200, B200, B300 and DGX Spark, plus AMD MI355X. Tenstorrent Blackhole and Cerebras CS-3 performance results are currently available for single-turn, single-query runs. 100
Adrian Jackson @adrianjhpc.bsky.social · 01/09/2026TEAS 🍵 identifies workloads with different profiles and bottlenecks (prefill, decode, tool use), as well as user choices (stack, batch regime, budget). It highlights the strengths of each accelerator and software stack in different scenarios rather than providing a one-dimensional ranking. 100

Adrian Jackson @adrianjhpc.bsky.social · 25/06/2026Memory architectures panel at #ISC26 it occurs to me Optane/3DXpoint is probably now economically viable. Can #Micron spin that fab back up? 030
Adrian Jackson @adrianjhpc.bsky.social · 12/03/2026I'd be the first to say precision is important, but I'm not sure this streaming TV UI has got it quite right 110

Adrian Jackson @adrianjhpc.bsky.social · 10/06/2025It's great to see UK systems high in the #Top500 list again, but I'm finding it hard to reconcile these two things.
