This is a development package for creating a high-level otf2 wrapper for tracing R scripts.

Wrapper built using Rcpp.

Using ZeroMQ socket to communicate with process responsible for otf2 logging.

Using PMPMEAS (Poor Man's Performance Measurement tool) to interface with papi/perf for performance metrics.

Install libotf2, and zeromq required dependency.

If metrics enabled (default: yes), install boost required dependency, and install papi optional (but recommended) dependency.

Then install rTrace from github with:

devtools::install_github("DylanKierans/rTrace")

Refer to debugging section if you are having errors.

1. Dependency not found during installation. Either dependency is not installed or is installed in non-standard directories.

   configure: error: Unable to find FOO.h
   ERROR: configuration failed for package ‘rTrace’
   

   Solution: if installed in non-standard dirctory pass the following argument to devtools::install_github where FOO can be one of the dependencies {zeromq, otf2, papi, perf, boost}.

   Example: Error - configure: error: Unable to find FOO_HEADER.h.

   devtools::install_github("DylanKierans/rTrace", configure.args="--with-FOO=/path/to/install/directory")

2. If you are receiving error about devtools not installed.

   Solution: install with

   install.packages("devtools") 

# <import packages>
# <define user functions>

# <...enter relevant area...>

# <...do work...>

# <...exit relevant area...>

instrumentation_finalize()
