A minimal implementation of causal profiling for Java applications running on Jikes RVM. Currently, this basically doesn't work. It'll only profile a very specific microbenchmark (included in the repo under the test package in the coff/src folder) at 100x overhead. So, it's basically useless but it's a start!
To run Coff on the microbenchmark, run the following command from the coff/src directory (where "rvm" is the path to the Jikes RVM executable in this repository): rvm -Xcoff test.Test after compiling Test.java with javac
For more information about Jikes RVM, visit the Jikes RVM website. Coff is built on top of Jikes RVM version 3.1.3.
Our work is based on Coz: Finding Code that Counts with Causal Profiling and you can find their code on github here.
