Conrad's DVO Worksheet

Introduction

The purpose of this page is to develop and introduction to using DVO from the complete perspective of a new non-astronomer user.

Logging into IPP and starting DV0

• Step 1) You need to do is log into an IPP machine that runs DVO. Example below:

$ssh -X -p 9005 ipp5u

Note: There is an X windows session and the port is 9005 and the machine ipp5u is only accessible internally to the cluster. If you need to ssh from an outside machine, see ​sshing.

• Step 2) Setup your psconfig to setup your ps lib configuration. Example below

  $psconfig --list
  PSCONFDIR : /home/panstarrs/ipp/psconfig
    Archives   : Archives
    lin64      : ipp-20120216
    lin64      : ipp-20120404
    lin64      : ipp-20120531-debug
    lin64      : ipp-20120531
    lin64      : ipp-eam
    lin64      : ipp-trunk
    bash       : psconfig
    csh        : psconfig
  $psconfig ipp-20120531
  

• Step 3) Launch DVO

  $dvo
  

Getting Started with DVO

If you have successfully launched dvo you will be see the dvo prompt. Several useful commands:

• ?? - Gives all the system environment variables available (i.e., HOME, PID, etc).
• ? - Shows all the available dvo commands .
• ! - Gives the ability to execute systems commands. Example:

  dvo: ! echo "Hello World"
  Hello World
  

• vectors - Tells you what variable vectors you have loaded into memory.
