Hello, I recently found myself missing a certain feature in PyCuda (and, in fact, the same can be said about PyOpenCL). Namely, the feature is a view of a part of GPUArray. For example, if I have some large array and want to perform some operation on the part of it, I have to introduce additional parameters like 'offset' and 'length':
a = GPUArray(full_size, dtype) func(a, offset=1024, length=2048) In my opinion, this can be too error-prone, and this would be better: a = GPUArray(full_size, dtype) a_view = a.get_view(offset=1024, length=2048) func(a_view) Now func() does not have to worry about offsets and can just work with a_view as if it were a common GPUArray. This especially helps if func() is some library function which you cannot/do not want to mess with. Other advantage of views would be that you can reuse some large temporary array by creating different views to use at different steps (instead of creating many temporary arrays which take more memory). So, at this point I am just interested whether I am the only one who will find this feature useful. Unfortunately, in the nearest future I will not have time to add it myself. I am not even sure whether it should go to PyCuda/OpenCL or straight to compyte (or is it there already?).
