To reply, visit: https://reviews.apache.org/r/48915/ ----------------------------------------------------------- Review request for mesos and Benjamin Mahler. Bugs: MESOS-5649 https://issues.apache.org/jira/browse/MESOS-5649 Repository: mesos Description ------- This framework is designed to show how to build a GPU capable framework that can accept offers with GPUs and launch tasks that use them. The key thing to remember is that the GPU_RESOURCES capability must be set in `FrameworkInfo` in order for a framework to receive resource offers from agents that contain GPUs. Diffs ----- src/Makefile.am a4931560f1a5b3fbe41ea181477341d3ac459b58 src/examples/gpu_framework.cpp PRE-CREATION Diff: https://reviews.apache.org/r/48915/diff/ Testing ------- Run a master and an agent capable of handing out GPUs: ``` $ sudo bin/mesos-master.sh --ip=127.0.0.1 --log_dir=/var/log/mesos --work_dir=/var/lib/mesos $ sudo bin/mesos-agent.sh --master=127.0.0.1:5050 --ip=127.0.0.1 --log_dir=/var/log/mesos --work_dir=/var/lib/mesos --isolation="cgroups/devices,gpu/nvidia" ``` Run a couple of instances of the framework and verify the correct output: ``` $ ./src/gpu-framework --master=127.0.0.1:5050 --num_gpus=0 $ ./src/gpu-framework --master=127.0.0.1:5050 --num_gpus=1 $ ./src/gpu-framework --master=127.0.0.1:5050 --num_gpus=4 $ ./src/gpu-framework --master=127.0.0.1:5050 --no-allow_gpus --num_gpus=1 ``` Thanks, Kevin Klues --===============8153413922755500165==--
