<div dir="ltr">Hi,<div><br></div><div>While i can see how this is benefitial for technical/farm usage, there are some concerns related on usefulness for Blender users:</div><div><br></div><div>- How difficult it is to set up such an OpenMP farm ?</div><div>- How much portable it is (Windows, OSX, Linux, BSD) ?</div><div>- What are the supported devices (my guess here is that there will be no GPU support, as in CUDA and OpenCL) ? </div><div><br></div><div>There are also some technical questions:</div><div><br></div><div>- Why is OpenMP better for final render? I would assume that could cause quite huge networking overhead.</div><div>- Why do we need some distributed device support which is rather limited to what OpenMP is offering instead of improving existing device_network.cc (that oen would at least support all GPUs, will allow to do some data cache etc..) ?</div><div><br></div><div>Those are the main concerns of having this device exposed to Blender users. On another hand, if all the changes are living in device_openmp.cc and kernel/kernels/openmp with minimal code overlap, i done feel against having devices which are used by tehcnical guys and not exposed to Blender users.</div><div><br></div><div>That's y current questions and thoughts here anyway.</div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sun, Jul 23, 2017 at 3:07 PM, Jaros Milan <span dir="ltr"><<a href="mailto:milan.jaros@vsb.cz" target="_blank">milan.jaros@vsb.cz</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<div dir="auto">I would like to create a new Blender client not only for distributed rendering ( offline + interactive ).</div>

<div dir="auto">It could use OpenMPI or Intel MPI ( for using more PCs with Intel Xeon Phis/GPU ).</div>
