arXiv – CS AI|Jingzhi Fang, Xiong Gao, Renwei Zhang, Zichun Ye, Lei Chen, Jie Zhao, Chengnuo Huang, Hui Xu, Xuefeng Jin|
🤖AI Summary
Researchers have developed DVM, a real-time compiler for dynamic AI models that uses bytecode virtual machine technology to significantly speed up compilation times. The system achieves up to 11.77x better operator/model efficiency and up to 5 orders of magnitude faster compilation compared to existing solutions like TorchInductor and PyTorch.
Key Takeaways
- →DVM addresses the long compilation time problem in dynamic AI models through runtime bytecode compilation instead of traditional machine code compilation.
- →The system uses a bytecode virtual machine that encodes operator programs on CPU and decodes them for direct execution on NPU.
- →DVM includes an operator fuser that performs both symbol-deduction-based fusion on static graphs and runtime fusion on dynamic graphs.
- →Performance testing shows up to 11.77x improvement in operator/model efficiency compared to existing frameworks.
- →Compilation speed improvements reach up to 5 orders of magnitude faster than current solutions like TorchInductor and PyTorch-eager.
