Introducing brae: GPU-native computational fluid dynamics. 🌊 The entire simulation runs on one GPU, no matrix shuffled back to the CPU every iteration. ~5× faster than GPU-accelerated OpenFOAM, on the same GPU. Validated to <1%. 🌐 brae.sh

Your GPU, earning while you sleep. Brae turns your NVIDIA GPU into income. One command to join. Renters pay by the minute, you keep 80%. Paid to your bank or in USDC. Early access is open → app.brae.sh Settlement in SIMD comes after our smart contract audit.
