HotPy (2) - A High Performance Binary-Compatible Virtual Machine for Python

Summary

[EuroPython 2012] Mark Shannon - 5 JULY 2012 in "Track Lasagne"

Description

HotPy (2) is a new interpreter for Python. It is binary compatible with CPython and reuses CPython’s object and module implementations. The core interpreter is new and uses many of the techniques developed during the 1990s and 2000s plus a technique developed during my PhD. Once the first stage of the optimisation chain is completed (May or June), HotPy is expected to be between 2 and 3 times as fast as CPython. It will probably never be as fast as PyPy, but it might be possible to get close. During the talk I will explain how it works (with lots of pictures), and how it compares to CPython and PyPy. I will also discuss whether the techniques used in HotPy would be suitable for Jython and IronPython.
