PacQ: Accelerating LLM Inference
A specialized microarchitecture for efficient mixed-precision computation
PacQ introduces a novel SIMT microarchitecture designed to optimize the inherent asymmetry in quantized large language models where weights are stored in low-precision integers while activations remain in full-precision floating-point format.
- Addresses the computation bottleneck in hyper-asymmetric GEMMs (General Matrix Multiplications)
- Leverages packaged computation units to efficiently process mixed-precision operations
- Achieves significant performance improvements for LLM inference while maintaining accuracy
- Provides a hardware-specific solution for the growing deployment needs of quantized LLMs
This research matters for engineering teams deploying LLMs at scale, offering a specialized hardware architecture that can significantly reduce computational overhead without sacrificing model performance.
