POD Architecture: Tools

PODStatus screenshot Checking your core hour and storage usage

PODTools is a collection of utilities for interacting with POD. POD users have access to a login node on POD via ssh. With PODTools, many operations such as submitting jobs, data transfers, and reporting can be handled securely with PODTools

  • PODReport is a command line tool to query your core-hour and storage utilization on POD. Options include the current usage, the previous billing cycle, and custom date ranges.
  • PODShell is a remote job submission and data-staging tool for POD. When installed on a user's client machine, it allows for job submissions directly to POD through the web (TLS encrypted). Users can bypass their login node completely or even do without. PODShell can also be used to copy data to and from POD, either independently or as job dependencies.

    Example: Submitting 2 jobs using PODShell, one with data transfers:

    [root@mojito ~]# podsh submit testjob.sub
Job Submitted successfully.
Job ID: 1567

[root@mojito ~]# podsh submit --stagein=mydata:~/data --stageout=myresults.log myjob.sub
Job Submitted successfully.
Job ID: 1590

    PODShell is a command line interface so it's scriptable, allowing automated workflows to POD without having to script SSH access and data transfers.

POD Web Services

POD Web Services is an API available to POD users interested in developing their own custom POD interactions. POD Web Services were designed to be easy to use and incorporate into your own scripting environment. Data payloads are in JSON format and all traffic is TLS encrypted.

POD status

Also provided is a command line tool used to monitor compute node utilization. When your jobs are running on POD, this tool will allow you to display CPU, network, memory and other utilization statistics for the specific nodes where your jobs are running.
