Full Changelog: v1.2.1...v1.2.2

v1.2.1

This release offers major performance improvements to the CUDA backend. It includes a new Virtual Pool Memory Manager (VPMM) in openvm-cuda-common that provides multi-stream memory management using CUDA driver APIs to avoid memory fragmentation. Several kernels in openvm-cuda-backend were also optimized to give significant performance gains.

Added

• (CUDA common) New memory manager with Virtual Pool (VPMM Spec) with multi-stream support built on top of the CUDA Virtual Memory Management driver API

Changed

• (CUDA common) Multi-arch build support
• (CUDA backend) Quotient values kernel optimization
• (CUDA backend) FRI reduced opening kernel optimization by removing bit reversal for better memory access patterns
