This procedure was used to run redistricting simulations with an R module called BARD (Better Automated ReDistricting). Since the same code needed to be run repeatedly for 2-200 seats and for all US states, a parallel computing environment was used. Read the rest of this entry »
OxCal is a freeware program, developed by the Oxford Radiocarbon Accelerator Unit (ORAU), University of Oxford. It applies a Bayesian approach for the analysis of archaeological and environmental chronological information. Binaries are distributed for the current version (v.4) for Mac and Win platforms.
The application consists of three main modules. The project manager and output module are web based, but the core analysis module is an executable, compiled from C++ source code and can be launched from the command line. It takes a plain text input file *.oxcal which contains the instructions for OxCal.
On a Mac this would look like, for example:
OxCalMac 6000_5950_SEQ.oxcal
To execute multiple runs of this, each one with a different (*.oxcal) input file – in our case a total of 1200 – I set OxCal up to run on an Xgrid. Read the rest of this entry »
