OpenSolvers benchmarks and tunes open-source scientific software and AI inference engines on real RISC-V hardware — OpenBLAS, FlexiBLAS, EESSI, HPL, Quantum ESPRESSO, llama.cpp, and friends. The results and fixes stay public.
Today we work on what we can buy and keep on the desk: SiFive U74 (VisionFive 2) and SpacemiT X60 / K1 (Orange Pi RV2, Banana Pi F3). That already uncovered real bugs (X60 gemv_n NaNs) and usable wins (U74 DGEMM, IME kernels, RVV backends).
Sponsorship is how we add platforms. Boards, shipping, power, and CI time are the bottleneck — not interest. Two platforms we especially want next:
- T-Head C910 — a widely shipped RISC-V core class we have not instrumented yet; different microarchitecture means different BLAS / RVV / app behaviour.
- SpacemiT K3 — the next step after K1 / X60 (RVA23, newer IME / vector story); we need silicon in-hand to extend the same kernel and app work beyond today’s RV2 / F3 results. Pico-ITX pricing (approx.): 8 GB ~$300 (BPI ~$293 / Sipeed $299), 16 GB ~$380–$400, 32 GB ~$575–$640 (Milk-V Jupiter 2 $575; Sipeed up to $639).
Your support buys those boards and the time to run the same careful A/B methodology on them — then publish the notes here and in opensolvers/benchmarks.
Near-term Sponsors goal: $300/month — covers an 8 GB K3 Pico-ITX to get started; stretch toward 16 GB (~$400) or 32 GB (~$600) for larger AI inference runs.
