k8s-openmpi

OpenMPI test on Kubernetes.

• Build and push worker docker image:

docker build -t rongou/openmpi-worker worker
docker push rongou/openmpi-worker

• Build and push launcher docker image:

docker build -t rongou/openmpi-launcher launcher
docker push rongou/openmpi-launcher

• Run the test:

kubectl create -f openmpi-test.yaml

This starts a StatefulSet of 4 workers, and a batch Job as the launcher. Logs can be accessed through the launcher pod.
