Sorry if this comes through multiple times, I've been having
problems posting from an email alias.
Andreas suggested I mail the mailing list and solicit comments here.
I submitted a pull request that adapts the element-wise kernels to support non-contiguous
arrays (including negative-strided arrays):
There have been a number of requests for this kind of functionality, so I'm hoping
this is useful (at least as a proof-of-concept). It passes all current PyCUDA tests, but
I've got some local code that fail for some more complicated cases. (Unfortunately
can't reduce it to a unit test yet) But most things work.
In some ways it's an elaborate monkey-patch meant to disturb existing code as little
as possible, but if you create your own element-wise kernels, to get the new functionality
you have to make a few changes.
More details at the above PR.
Anyway, if anyone is interested in trying it out, I'd be interested to hear how it
works for you, or whether you have suggestions for fixes. The code is in my fork:
in the 'noncontig' branch.
Please help take a look and help review the code. If there's one thing I'm
super short of these days, it's code review bandwidth. And so it helps a
lot if potential issues get highlighted and discussed. Thanks!

Also, thanks again Syam for working on and submitting this!
