This package contains some testing code for running a QuickAna-based analysis application on HPCs such as Edison (and eventually Cori). For the sake of comparisons, functionality is included to run the application in various modes using a few different EventLoop drivers. The application can run directly on an interactive node, can run on the PDSF batch system, and can run using PROOF-lite on either a local node or a batch system like Edison.
The application is based on EventLoop and QuickAna. It processes systematics and applies the (mostly default) object definitions of QuickAna. The output is currently a set of kinematic histograms for each systematic. Python is used to configure, steer, and submit the application to various EventLoop backends.
- AnalysisAlg - A simple EventLoop Algorithm for running QuickAna. It has a configuration flag for disabling systematics. It books and fills the output histograms.
- runQuickAnaHPC.py - Executable python script
which configures and launches the application. Has several command line
options for specifying the input samples, the driver to use, and various
other job configuration options.
- The
--task ID:Noption allows to specify a chunk of the input data for processing. The process will only use the ID-th chunk of size 1/N of the input samples. If samples are broken up into individual files, this is a useful way to distribute files evenly across separately submitted tasks.
- The
- Python modules - Utility code for sample management, logging, and loading RootCore libraries. Can be expanded as necessary. I may move some machine-specific or driver-specific setups in here.
- Edison example submission scripts in scripts.
