Building Faster Cryptography with Carryless Multiplication in NVIDIA CUDA 13.3Β
For over fifteen years, x86 CPUs have shipped with a dedicated hardware instruction for carryless multiplication. Itβs a small but stubborn primitive that sits underneath authenticated encryption, error-correcting codes, and modern zero-knowledge proofs. Until now, NVIDIA GPUs lacked native support for this operation. NVIDIA CUDA 13.3 closes that gap with , a new PTX instruction available onβ¦
