Hello, Does PyCUDA support struct arguments to kernels? From the Python side it means an element of an array with a struct dtype (a numpy.void object), e.g. dtype = numpy.dtype([('first', numpy.int32), ('second', numpy.int32)]) pair = numpy.empty(1, dtype)[0] See https://gist.github.com/Manticore/15383a1ae367bfc6efe8 for an example of the functionality in question. It fails on ``get_second()`` call complaining about the second argument (the structure). An analogous code in PyOpenCL works fine, but as far as I understand from its source, it uses a somewhat different mechanism of argument passing as compared to what is employed by PyCUDA.
