Revolutionizing DL Compilation with Task Graph Caching
Accelerating TVM auto-tuning for enterprise-grade Deep Learning deployments.
Executive Impact
This analysis reveals how Task Graph Caching (TGC) significantly enhances the efficiency of Deep Learning (DL) model compilation within the TVM framework. By leveraging cached optimization sequences, TGC reduces auto-tuning time by up to 3.13x on CPU and 3.25x on GPU, while maintaining high model inference performance. This approach streamlines the DL development cycle and lowers operational costs across diverse hardware architectures.

Background
Deep Learning (DL) models are crucial across many applications, demanding fast execution on diverse device architectures. DL compilers like TVM optimize high-level models into efficient low-level code. However, the vast optimization sequence space leads to lengthy compilation times, impacting the design cycle. TVM's auto-tuning relies on evolutionary algorithms to explore this space, which is computationally expensive.
TGC Algorithm
Task Graph Caching (TGC) is a novel algorithm designed to reduce TVM compilation time by reusing previously discovered optimization sequences. It identifies similar DL subgraphs across models and stores their high-performance optimization sequences in a cache. When a similar subgraph is encountered, TGC seeds the evolutionary search with these cached sequences, accelerating convergence and avoiding redundant exploration.
Experimental Results
Experiments on twelve DL models show TGC significantly speeds up auto-tuning. For Ansor on CPU, auto-tuning time is reduced by up to 2.89x, and for MetaSchedule, by 3.13x. On GPU, MetaSchedule sees a 3.25x speedup. Crucially, TGC maintains or even enhances the inference time achieved by default TVM, demonstrating its practical value for accelerating DL model compilation without performance degradation.

DenseNet121 Compilation Speedup
For the DenseNet121 model on CPU, TGC reduced auto-tuning time from approximately 36 hours to 12 hours with MetaSchedule, and from 18 hours to 7 hours with Ansor. On GPU, the time was cut from 35 hours to 11 hours. This demonstrates a significant improvement in auto-tuning efficiency, translating directly to faster development cycles and reduced cloud computing costs for large-scale DL deployments.
