Bringing Cython and PyPy closer together
by Stefan Behnel April 1, 2012

April 1, 2012

Hi, I'm breaking out of the thread where this topic was started ("offtopic, ontopic, ...") because it is getting too long and unfocussed to follow. The current state of the discussion seems to be that PyPy provides ways to talk to C code, but nothing as complete as CPython's C-API in the sense that it allows efficient two-way communication between C code and Python objects. Thus, we need to either improve this or look for alternatives. In order to get us more focussed on what can be done and … [View More]

Profiling pypy code
by Timothy Baldridge April 1, 2012

April 1, 2012

I've been trying to find ways to optimize my clojure-on-python project. And I've been running through my code in jitviewer. However it seems that jitviewer only displays the number of times a given loop was run. What should I look into for benchmarking actual times spent in each loop? It seems that my optimization efforts would be best spent on areas of code that have a high hit count AND have a long execution time. Any ideas? Thanks, Timothy -- “One of the main causes of the fall of the … [View More]
