The blog post delves into the optimization techniques for deep learning workloads on the Fireworks Gen AI Platform, highlighting the significant advancements in GPU speed and the resultant bottleneck posed by the host CPU. It emphasizes the use of CUDA graphs, introduced in CUDA 10, which enable the recording and replaying of GPU kernels to reduce CPU overhead, thereby enhancing performance without sacrificing usability. The post describes how CUDA graphs offer a 2.3x speedup in LLaMA v2 inference tasks by addressing CPU overhead and maintaining GPU activity, as demonstrated on the Fireworks Inference Platform. It also discusses other optimization approaches like torch.compile in PyTorch 2.0 and highlights the trade-offs between flexibility and performance. The platform's Python-based codebase leverages these techniques, including multi-query attention, to deliver industry-leading inference performance, supporting models such as LLaMA and StarCoder.
