  • Decide between actx.np.zeros and actx.zeros.
  • zeros_like doesn't currently retain metadata from its argument, resulting in lazy compile issues.

    actx.zeros doesn't work on containers (like all the other methods in actx), so they're not quite equivalent. Should it?

    I don't see why it shouldn't. actx.freeze is (legitimately) growing container support (#158).

    Did some of this work in #178:

    • actx.zeros_like and actx.empty_like work on containers.
    • at least the eager pyopencl version propagates tags in both of those.

    actx.zeros and actx.empty can't really get support for array containers, since they don't have a template to mimic. Also, there's no actx.np.zeros, so that should be done as well!

    Thanks for working on that!
