This command launches a single mobject server daemon, which uses na+sm protocol and which writes a cluster config file to /tmp/mobject-cluster.gid (clients use this config file to connect to the cluster). Similarly, for a cluster of multiple servers, MPI is used:
Another way to deploy an example Mobject cluster is to use the mobject/demo Docker container available at https://xgitlab.cels.anl.gov/sds/sds-docker. This image installs mobject-store (and all of its dependencies) on a base Ubuntu image, then launches a single Mobject server daemon that a user can interact with as if the daemon was running on the host system. Instructions for building/running mobject/demo are provided in a README in that repo.
We additionally provide details on how to deploy a simple RADOS cluster, as mobject-store supports a subset of the RADOS API. Codes that use this subset of the RADOS API can be easily made to run with a RADOS backend or a mobject-store backend.
Currently, we only have instructions on how to deploy a RADOS cluster using the ceph/demo Docker container (https://hub.docker.com/r/ceph/demo/). This website includes details on how to pull that image from Docker Hub and how to run the container. An example command to run this container is:
