[Numpy-discussion] new memcpy implementation exposes bugs in some software.

Hi All, Apparently the 64 bit version of memcpy in the Fedora 14 glibc will do the copy in the downwards rather than the usual upwards direction on some processors. This has exposed bugs where the the source and destination overlap in memory. Report and discussion can be found at fedora bugzilla

[Numpy-discussion] Is numpy.convolve based on LAPACK routine?

Hi everyone, I am wondering, is numpy.convolve based on LAPACK routine? Can it be speedup by using ATLAS? Sincerely, LittleBigBrain ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion

[Numpy-discussion] C-compiler options

Hi: I'm trying to build numpy with python27, 64-bit, on OSX 10.5.8. When I run python setup.py build, only 32-bit binaries get built. I can see what is happening is that not 64-bit flags are getting passed to the c compiler (I don't know about the fortran compiler. So I have two questions;
