[Cython] OpenMP 4.5 array reductions

2018-08-31 Thread Nathan Goldbaum
Hi all, I'm curious if there would be any interest in adding support for OpenMP 4.5 array reduction in the cython compiler or alternatively detecting these cases and raising a cython compiler error. Currently cython is generating code that will compile but might lead to race conditions. See: htt

[Cython] #cython on freenode

2018-08-08 Thread Nathan Goldbaum
Hi all, The Freenode IRC network is currently undergoing a spam attack that is affecting the #cython channel there. People definitely do use #cython to ask questions. I and some others try and help them out. It would be a shame to have that community, such as it is, get destroyed by the spam atta

It would help if cython could generate compiler warnings for a release or two about py2-specific constructs before officially switching the default language level. On Mon, May 28, 2018 at 2:14 PM Stefan Behnel wrote: > Hi, > > Python 3 is clearly taking over the world these days, so it starts fe

Hearty +1 to getting a cython release out. I'd like to get this fix which will substantially speed up some code I've written on multicore systems: https://github.com/cython/cython/commit/8dbc7c39d1f1a3b675f69dceaac281 7b7675ca09 -Nathan On Mon, Jun 12, 2017 at 1:00 PM, Stefan Behnel wrote: > R

Hi all, To reproduce this issue, be on cython 0.22 and IPython 3.0 and run the following notebook: http://nbviewer.ipython.org/gist/ngoldbaum/855a629d997aa7959254 Googling the error returns some several year old discussions in IPython related to the autoreload magic and I'm not sure if that is a
