I know GPU renderers take advantage of multiple GPU's, but does H16 OpenCL performance also benefit?

as far im aware not multi GPU support

it's sad… i have a 6 x GTX 1070 SC on my computer, 2 on PCI 16x, others in 1X via risers

will be wonderfull if we can take advantage of opencl distributed on all gpus for grains, and even FEM.

Blender Cycles and Octane take advantage of all gpus, even on the ones on risers. it is very nice on my tests, almost absolut speed increase for each GPU.

I am imagining near future possibility to use this on FEM for muscle simulations H17??, Houdini segmenting problem on multi-gpu system, this can open a myriad of possibilities on complex simulations that fit on GPU memory.
