Create and Manage Cloud Clusters with MathWorks Cloud Center

• Machine type: types vary by hardware specification including number of cores,
memory, and GPU support.
• MATLAB version.
• An optional timeout for the cluster so that it shuts down automatically:
• When cluster is idle: When the cluster no longer has any jobs to process,
it will eventually shut itself down after a few minutes if no more work is
submitted. This option is available only on clusters of MATLAB version
R2014a and later.
• After a set time period: The cluster shuts down after the specified
amount of time, whether busy or idle.
• Never: The cluster continues to run until you manually shut it down.
• SSH key name
The SSH key is required to start and log in as root to your cloud cluster nodes.
Cluster nodes have no password, so you use a key to log in using SSH. When you
create a cluster, you can select from the existing keys for the specified region of
your AWS account, or you can request that Cloud Center create a new key.
If you click create a new key, the following dialog appears for you to provide a
name.
Enter a name, and click Download Key. Your browser might require you to
identify a location for the download. This is a root access key file having the
extension .pem. Do not lose this file, because you cannot download it again.
(However, you can always create a new key, and download its key file.)
You can specify the same SSH key for multiple clusters. Cloud Center also makes
available a non-root user access key file, unique to each cluster. For information
