Antoine Legault, CFA, CPA The newest TOP500 list capturing the largest 500 (self reported) supercomputing

(626) 497-1619 systems was released earlier this week. With shifts in supercomputing often

antoine.legault@wedbush.com foreshadowing changes in the broader IT landscape, we see technology trends

highlighted by this list as meaningful even though the HPC space represents a

relatively modest portion of total IT spend:

Key Takeaways

A New Leader, but on CPUs Alone: In a more eventful list at the top than the past

several, a previously unlisted Chinese system, LineShine, debuted at No. 1 at 2.198

Exaflop/s on HPL, one of two new Top 10 entries this list (alongside Eni's HPC7 at

No. 6) versus none last list. LineShine ends a run of US based HPE built systems

atop the list that dated to Frontier's 2022 exascale debut and marks the first China

based leader since 2017.

We would highlight LineShine's lack of accelerator use; the platform rather relies

solely on a custom Chinese CPU platform. And this architecture in turn appears less

useful for AI workloads (its HPL-MxP mixed precision speedup of just ~3.6x (versus

~8x to 11x for the GPU accelerated US systems).

If indeed Supercomputing efforts provide some insight into future tech trends (and

we believe they do), the lack of an AI accelerator seemingly suggests China is still

struggling to replicate NVDA/AMD/Western efforts in AI processing, an implication

we see as positive for NVDA et al (particularly with regards to training).
