[Numpy-discussion] Making a minimalist NumPy

2007-11-04 Thread Benjamin M. Schwartz
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 NumPy is included in the OLPC operating system, which is very constrained in space. Therefore, it would be nice to remove some subpackages to save a few megabytes. For example, the system does not include any Fortran code or compiler, so f2py (3.6 MB

[Numpy-discussion] Single-Precision FFT

2007-05-24 Thread Benjamin M. Schwartz
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I am working on two programs using NumPy for the OLPC project. In both cases the performance is limited by the FFT. The OLPC machine uses a AMD Geode CPU, which is generally slow, but especially bad at double-precision floating point. It would be a ma
