- VOLT (Vortex-Optimized Lightweight Toolchain) is an open-source GPU compiler designed to support SIMT execution on emerging open GPU architectures.
- The compiler framework is technically complex and often underestimated in open hardware development costs.
- VOLT enables SIMT code generation and optimization across multiple levels of abstraction through a hierarchical design.
- It centralizes fundamental SIMT-related analyses and optimizations in the middle-end for reusability and adaptability to new GPU variants.
- Two case studies demonstrate VOLT's support for ISA extensions and host-runtime API extensions.
