Feature Specific Profiling for R

Abstract:

Programmers use profilers to understand the performance characteristics
of their programs and to focus on those pieces whose improvement may
yield the largest gains. A conventional profiler measures the time that
a program spends in functions, methods, expressions, and statements.
Racket's novel feature-specific profiler supplements this information
with timings of instances of linguistic features. This paper reports the
results of a successful reproducibility effort to adapt feature-specific
profiling to the R programming language. Specifically, the paper
demonstrates how easy and effective it is to add the necessary language
support, that the approach usefully enhances the information produced by
a classical profiler, and that the additional overhead is tolerable.

Bio:
Leif Andersen is a second year Ph.D. student at Northeastern University, studying programming language
with Matthias Felleisen.
