CyberShake DAX Generator

This page provides an overview of the CyberShake DAX generator, which includes all the Java classes associated with producing DAXes for any kind of CyberShake workflow.

The source for the DAX generator is available at http://source.usc.edu/svn/cybershake/import/trunk/dax-generator-3/ . All required dependencies are in the lib directory, though the Pegasus JAR may need to be updated if new Pegasus API features are used.

The DAX Generator is fairly complex, as we have retained backwards compatibility, even though some of the options may not have been used in several years.

Java classes

The DAX generator package consists of:

• CyberShake_AWP_SGT_DAXGen.java: Creates workflow with all SGT jobs except PreCVM. This is because, when running AWP-ODC-SGT in CPU mode, we need to figure out the box dimensions in PreCVM before we can determine the number of processors we'll need in each dimension, so after PreCVM an AWP subworkflow is generated.
• CyberShake_DB_DAXGen.java: Generates a sub-workflow with the database and data product jobs.
• CyberShake_Integrated_DAXGen.java: Entry point for generating a full ('integrated') workflow.
• CyberShake_PP_DAXGen.java: Entry point for generating a post-processing workflow. Is also called as part of creating an integrated workflow.
• CyberShake_SGT_DAXGen.java: Generates an SGT-only workflow, by calling PreCVM and then CyberShake_AWP_SGT_DAXGen if running AWP-ODC-SGT.
• CyberShake_Stochastic_DAXGen.java: Entry point for generating a stochastic-only post-processing workflow.
• CyberShake_Sub_Stoch_DAXGen.java: Most of the guts of generating a stochastic-only post-processing workflow. Since we need velocity model information as input to some of the stochastic codes, we generate the velocity model information in CyberShake_Stochastic_DAXGen, then pass the file to this class as an input at creation time. That way we can put the velocity in as a command-line parameter, rather than having to have every task read the same velocity file.
