Dumpstack

This repo demonstrates how to dump the CppAD stack from TMB and visualize the computational graph.

Requirements

  • Command line tools: 
    apt-get install graphviz inkscape
  • Upcoming TMB version 1.7.12 or current master branch installed using make cran-version.

General usage

To enable tracing of the operation stack compile a model using:

compile("model.cpp", tracesweep=TRUE)

This will set the preprocessor flag CPPAD_FORWARD0SWEEP_TRACE.

To dump the stack use

obj$env$f(dumpstack=TRUE)

Examples

R --slave < dumpstack.R
