Subject: [OMPI devel] RFC: Add some basic CUDA-aware support to reductions
From: Rolf vandeVaart (rvandevaart_at_[hidden])
Date: 2014-05-14 09:55:11


WHAT: Add some basic support so that reduction functions can support GPU buffers.
All this patch does is move the GPU data into a host buffer before the reduction call and move it back to GPU after the reduction call.
Changes have no effect if CUDA-aware support is not compiled in.

WHY: Users of CUDA-aware support expect reductions to work.

WHEN: After next con call, May 20, 2014

See attached patch.
