Aligned allocator for numpy (Trac #568) #4371

Open numpy-gitbot opened 12 years ago

Original ticket http://projects.scipy.org/numpy/ticket/568 on 2007-08-11 by atmention:cournape, assigned to unknown.

Here is a first patch to have aligned allocator in numpy: this does not give yet a high interface to create arrays with a given alignment, only aligned allocators in the array interface.

The patch:

defines aligned allocators
Make PyDataMem_* macro to point to the aligned allocator with a default alignment (fixed to 16 bytes)
Define new macro PyDataAligned_* to align buffer with arbitrary alignment

David, what is the status of this?

That's something which needs more thinking and work (in particular, we need a small cpu capability detection if we want to use SSE and co in numpy, and aligned allocators are only useful when used with SSE and co in numpy), and anyway can't be integrated for 1.0.5
