Class CmdShell

source code

shell

Load an interactive IPython shell configured for starcluster development

The following objects are automatically available at the prompt:

    cfg - starcluster.config.StarClusterConfig instance
    cm - starcluster.cluster.ClusterManager instance
    ec2 - starcluster.awsutils.EasyEC2 instance
    s3 - starcluster.awsutils.EasyS3 instance

All StarCluster modules are automatically imported in the IPython session
along with all StarCluster dependencies (e.g. boto, paramiko, etc.)

If the --ipcluster=CLUSTER (-p) is passed, the IPython session will be
automatically be configured to connect to the remote CLUSTER using
IPython's parallel interface (requires IPython 0.11+). In this mode you
will have the following additional objects available at the prompt:

    ipcluster - starcluster.cluster.Cluster instance for the cluster
    ipclient - IPython.parallel.Client instance for the cluster
    ipview - IPython.parallel.client.view.DirectView for the cluster

Here's an example of how to run a parallel map across all nodes in the
cluster:

    [~]> ipclient.ids
    [0, 1, 2, 3]
    [~]> res = ipview.map_async(lambda x: x**30, range(8))
    [~]> print res.get()
    [0,
     1,
