New hardware extension Ventaglio boosts Transformer inference speed

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel hardware extension called Ventaglio, designed to significantly accelerate sparse tensor contractions on vector processors, a critical operation for Transformer model inference. This extension, integrated into a 12nm FinFET cluster, provides native support for indexed gather-accumulate-scatter operations, overcoming limitations in existing RVV architectures. Ventaglio achieves substantial speedups, ranging from 6.9x to 7.4x over optimized baselines, and demonstrates practical performance gains of 2.06x to 5.25x on a DuoGPT-pruned LLaMA-3-8B model with dual sparsity. AI

IMPACT This hardware innovation could lead to more efficient and faster deployment of large language models, reducing inference costs and latency.

    At-the-Roofline Sparse Tensor Contractions on Vector Processors for Transformer Inference

    arXiv:2607.25504v1 Announce Type: cross Abstract: Fine-grained weight pruning and activation sparsification have emerged as effective approaches for reducing the compute and memory cost of inference for Transformer models. In the moderate-sparsity regime, Gustavson's dataflow pro…
