[SciPy-user] Distributed Array Library?

Out of curiosity, how had you all been thinking about doing this?

One thing that had come to my mind was somehow one might use  
GlobalArray as a back-end and the ndarray interface as a front-end,  
but so much of the ndarray code assumes that one can use pointer  
arithmetic to access the data that I couldn't see a good way to make  
this work.  Is there a clever way of implementing a distributed array  
that would allow one to re-use as much of the numpy core code as  
possible?

Thanks again,
Greg
