pyston/pyston_v1
Pyston V1
Pyston is a high-performance Python language implementation and JIT compiler. It functions as a runtime environment that executes Python code while maintaining compatibility with the standard language specification.
The project accelerates execution by translating Python bytecode into native machine code during program execution. It utilizes a multi-tier compilation pipeline and adaptive execution optimization to transition from interpretation to compiled code based on runtime behavior. This implementation maintains binary compatibility with the standard Python C API to support native extensions.
The runtime includes tools for performance optimization and benchmarking, including the ability to toggle between compilation tiers and interpreter modes. It provides monitoring and observability features such as internal statistics export and configurable runtime verbosity for diagnostic logging and execution analysis.
