Together AI releases open-source Parallel Kernel Builder for LLM inference

By PulseAugur Editorial · [1 sources] ·

Together AI has released Parallel Kernel Builder (PKB), an open-source tool designed to optimize inference performance for large language models. PKB can identify and generate novel kernels, such as those for NeMo vocab-parallel log-probs and Hyena context parallelism, which are not publicly documented. The tool has demonstrated significant speedups, with one kernel achieving 87.9µs compared to the standard 320.6µs for NCCL, and the project encourages community contributions. AI

IMPACT Optimizes LLM inference performance, potentially leading to faster and more efficient AI deployments.

    Single-shot generation still surfaces net-new kernels with no public reference: NeMo vocab-parallel log-probs, Hyena context parallelism, SAM 3 mask suppression

    Single-shot generation still surfaces net-new kernels with no public reference: NeMo vocab-parallel log-probs, Hyena context parallelism, SAM 3 mask suppression. One GEMM + All-Gather kernel hit 87.9µs vs 320.6µs for NCCL. PKB is open. Read more and contribute below. Blog: …
