Transfer Data to or from a Cloud Cluster

1-25

The -remotehost name is available in Cloud Center under the details for the head

node of a running cluster.

With the data files in place on the cloud cluster nodes, you can specify their location

in the job’s AdditionalPaths property to provide access to them for the MATLAB

workers.

Retrieve Data from the Cloud

This example shows how to copy the file /shared/persisted/emem.mat from a cloud

cluster node to a local UNIX machine as /home/cloudtmp/return_emem.mat.

cd /matlabinstall/toolbox/distcomp/bin

./remotecopy -local /home/cloudtmp/return_emem.mat \

-from -remote /shared/persisted/emem.mat \

-remotehost ec2-107-21-71-51.compute-1.amazonaws.com \

-protocol scp -username clouduser -identityfile /home/.ssh/your-key.pem \

-passphrase ""

(For Windows, use appropriate slashes, path names, and ^ to indicate continuation of the

command on multiple lines. For other options or information about mixed platforms, see

remotecopy -help.)

The -remotehost name is available in Cloud Center under the details for the head node

of a running cluster.

Retrieve Data from Persisted Storage Without Starting a Cluster

This procedure describes how to retrieve your persisted data from Amazon EC2, without

starting a cluster to access /shared/persisted. The major steps are described in the

following subtopics:

1. “Find Persisted Storage Resources in AWS” on page 1-25

2. “Launch Instance or Attach Volume to Existing Instance” on page 1-26

3. “Mount Volume for Access” on page 1-28

4. “Transfer Data” on page 1-29

Find Persisted Storage Resources in AWS

Management Console and access your Amazon EC2 Dashboard.

On the right side of the tool bar at the top of the page, select the Region that your

cluster is located in.

In the left side navigation pane, select Elastic Block Store > Snapshots.
