Introduction

The IPP Simulation Test ("Simtest") has been revised to be more automatic than its previous incarnations. The desire has been for it to run through with the least possible amount of user intervention and interactivity. At the present time (release 2.6), it requires a few pantasks commands to set up, and will run all the way through the creation, registration, detrend, chip, camera, fake, warp, stack, and diff stages; the magic stage will also be populated, though not run.

WARNING

This page refers to the revised Simtest, which will not be released until IPP 2.6. If you are using an earlier version of the IPP (e.g., 2.5.1), then these instructions are not relevant to you.

Instructions

Having installed the IPP, go to a fresh directory.

user@computer:/path/to/simtest>pantasks
 
Welcome to pantasks - parallel task scheduler
 
 
pantasks: module simtest.pro
pantasks: simtest
USAGE: simtest (testroot) (dbname) (hostname) (init)
 if (init) == 0, just run the analysis tasks
 if (init) == 1, (re)create the database and (re)inject the images
 if (init) == 2, restart completely from scratch
pantasks: simtest simtest.basic dbname computer 2

Here:

• simtest.basic specifies the setup (see ippTasks/simtest.basic.config). *dbname is your database name: it must have already been set up (e.g., using dbadmin), though it needn't have been created (using pxadmin) since the simtest will do that, depending on the init value you give it.
• computer is the name of a processing node: you must be able to ssh to this node without it prompting for a password.
• The init value (in the example here, 2) specifies what needs to be done.

After this, the database will be (re)created, simulated images will be generated, and the usual processing should automatically take place all the way through to the diff stage. As usual, you can track how things go using the status command in pantasks, or using the IPP Monitor (if you've got it set up).
