Hi, Just a heads-up on something they're talking about over at CorePy.
Regards Stéfan ---------- Forwarded message ---------- From: Andrew Friedley <afrie...@osl.iu.edu> Date: 2009/6/8 Subject: [Corepy-devel] New ExtBuffer object To: CorePy Development <corepy-de...@osl.iu.edu> I wrote a new buffer object today, called ExtBuffer, that can be used with libraries/objects that support the Python 2.6 buffer interface (e.g. NumPy). This brings page-aligned memory (and huge-page) support to anything that can use a buffer object (eg NumPy arrays). ExtBuffer can also be initialized using a pointer to an existing memory region. This allows you, for example, to set up a NumPy array spanning a Cell SPU's memory mapped local store, accessing LS like any other NumPy array. The ExtBuffer is included as part of the 'corepy.lib.extarray' module, and can be used like this: import corepy.lib.extarray as extarray import numpy buf = extarray.extbuffer(4096, huge = True) array = numpy.frombuffer(buf, dtype=numpy.int32) I wrote a some documentation here: http://corepy.org/wiki/index.php?title=Extended_Array If anyone has any questions, thoughts, ideas, bugs, etc, please let me know!
