I run on a machine with four GPUs and can individually select which one I want to use by calling ‘CUDA_VISIBLE_DEVICES=0 rtkfdk ...’ or ‘CUDA_VISIBLE_DEVICES=1 rtkfdk …’ which exposes the target GPU to the running application. This is a very manual, command line approach, however the CUDA_VISIBLE_DEVICES variable can also be set to a unique value for each user in their respective user profile (e.g. setting </span>‘CUDA_VISIBLE_DEVICES=1’ for USER1 in ~/.bashrc on a Linux machine<span class="">). This second approach makes it so that each user has a dedicated GPU at their disposal whenever they need it.</span><div class=""><span class=""><br class=""></span></div><div class=""><span class="">Hope this helps.<br class=""></span><div class=""><br class=""></div><div class="">— Matt</div><div class=""><div class="">
