I was wondering if anyone could point me to a more in-depth explanation of why we are (currently) restricted to using a special-purpose standard Prelude when writing vectorised code with DPH. We're prototyping using several data-parallel languages for a research project here at Northwestern University, and wanted to get a better idea how we might go about adding vectorisation support for addtional types/operations.
There are certain simple operations which don't appear to be supported for primitive types yet (e.g. the ^ and ** operators for an Int type). These are the kinds of things we'd like to look into as a first step. Also - there are several papers which mention foldP as being part of the (prospective) implementation, but I couldn't find this in any of the modules. Has this one not been implemented yet? Much thanks, James Swaine
