I am an open source contributor of Pyston, and working on NumPy Pyston support(Pyston: https://github.com/dropbox/pyston)

I disabled some tests which cause segfaults. This is current situation(in my local branch):

----------------------------------

----------------------------------

Indeed, the time consuming was longer than CPython. I think this is because of the additional exceptions / frame introspection etc... And no one took yet a look at the perf.

Pyston runtime miss some features. I will try to fix the problems which discovered in running NumPy test suite.

This is basically an announcement. I will update the situation when I get breakthrough, ask for help if I encounter problems, submit commit to NumPy if needed.

Looking for feedback.

Regards,

Sun
