Cluster Shared File System
When you create and start a cluster, shared folders are created for the storage of your
data. These folders are shared by all the nodes of your cluster, but have different
longevity, according to the following table. The path is the same for all nodes of the
cluster.
Location Size Longevity
/shared/persisted Specified at cluster creation Deleted when cluster is
deleted
/shared/tmp 1.6 TB or more Deleted when cluster is
stopped
/shared/imported Part of allocation for
/shared/tmp
Deleted when cluster is
stopped; copied again when
cluster is started
For the duration of their existence in the cloud, you can use these folders for storing data
generated by your jobs, and for data you want to transfer between the cluster and your
client location. See “Transfer Data to or from a Cloud Cluster” on page 1-21.
Cloud cluster nodes can share these folders only with nodes of the same cluster; that is,
there is no file sharing between different clusters.
You create, start, stop, and delete your cloud clusters independent of your local MATLAB
session. Deleting an associated cluster object in MATLAB does not affect the cloud
cluster or its persistent storage.
When a cluster times out, it shuts down and clears the contents of /shared/tmp and
/shared/imported, but preserves the content of /shared/persisted. If you use an
automatic shutdown setting for your cluster, be sure you have all data you need from
/shared/tmp before this timeout occurs.
