Show HN: CrossingBench – Modeling when data movement dominates compute energy
I built a small reproducible microbenchmark exploring when system energy becomes dominated by boundary crossings rather than intra-domain compute.
The model decomposes total energy into:
C = C_intra + Σ V_b · c_b
Includes:
CLI sweeps
Elasticity metric (ε) as a dominance indicator

Looking for critique, counter-examples, or prior related work I may have missed.
- verdverm 9mo agoAre you looking to publish this eventually? It reminds me of the CPU simulators and VSLI tools my peers worked on during graduate school, the department had a big arch and systems focus.
- JessyMorissette 9mo agoYes — I’m exploring publication. I released the benchmark early so the model can be scrutinized and reproduced before any formal submission. I’d especially value feedback from architecture and systems researchers.
- verdverm 9mo agohmmm, you sound like a bot with this reply, are you wanting me to provide said feedback that you would value from architecture and systems researchers?
- JessyMorissette 9mo agoDefinitely not a bot And yes — I’d genuinely appreciate your take. If this overlaps with prior arch or systems work you’ve seen, pointers would be really helpful.
- verdverm 9mo agoI don't have that expertise, I assume the tools they use are easily searchable and well known
- JessyMorissette 9mo agoGot it, thanks
