Data that is stored in job and task properties is available to the client, so your task or
batch function results are accessible from the finished job’s fetchOutputs function or
the tasks’ OutputArguments property. For batch jobs that run on the cloud, you can
access the job’s workspace variables with the load function in your client session.
Download SSH Key Identity File
Among the cluster information in Cloud Center is the SSH key for that cluster, for non-
root user access. Follow these steps to download a cluster’s SSH key identity file:
1
In Cloud Center, click My Clusters.
2
In the list of your clusters, click the cluster whose key you want to download.
3
In the Cluster Summary display, click More Details to expand the display.
4
In the SSH Keys information field is a hyperlink labeled User Access. Click this
link to download and save the key (.pem) file to your local client machine.
You can use your saved .pem file for SSH or other access to the cloud nodes for
transferring data, as described in “Transfer Data with Standard Utilities” on page
1-22 and “Transfer Data with the remotecopy Utility” on page 1-24.
Note that the only key available here is for user access (username clouduser), not for
root access. A root access key (user name: ubuntu) is provided only when you create a
new cluster. If you require, but do not have access to the root private key for a cluster,
you could create a new cluster using another key for which you do have access, or create
a new key according to the SSH key name description in “Create a Cloud Cluster” on
page 1-4.
Transfer Data with Standard Utilities
In these examples, suppose you want to transfer the file /home/cloudtmp/emem.mat
to the folder /shared/persisted on the head node of your cloud cluster. Instead of
providing passwords, you use an SSH key identity file, which is the private key file you
download from a cloud center cluster as described in “Download SSH Key Identity File”
on page 1-22.
This section highlights only a few of the many file transfer utilities that are available.
