OpenMP specification example extracting tools

Postby estrabd » Thu Oct 13, 2011 9:23 am

I am posting this here because I know all the good folks at the ARB pay close attention to the forums; I have finally gotten around to releasing the suite of Perl and Bourne shell scripts that I created to assist in the extraction and testing of the examples in Appendix A.

I know that there are other solutions out there, but this suite includes means to extract, test/report, and maintain examples in a larger context.

My idea was that a master of all examples be in a single text file; each example is delimited and has a language appropriate comment block containing useful meta-data. There is a tool that will split this single file into separate files and has the ability to do certain things based on the meta-data. Additionally, the meta-data would allow the testing framework to determine if this was a snippet or full program, if this was supposed to be a valid example, a counter example (either should fail to compile, be compilable but non-conforming, etc), or whatever. All of that is a lot less developed than part of the code that actually extracts the code snippets from the PDF. Lastly, the testing script is just a basic one that attempts to allow one to test using a variety of compilers; there's a post processing script that can take the output of various test runs and display (in an HTML table matrix) what examples compiled/failed for what compilers - and links to any errors encountered.

Regarding testing, I wanted to point out that there is something called the "Test Anything Protocol" (TAP) that would be useful in this context; my scripts don't report in this format, but could. Furthermore, there is a "libtap" in github that allows one to do fairly standard testing using a TAP harness. It might be useful thing to standardize all tests, validation suites, and benchmarks on. Cray's Chapel language distribution also comes with what I believe to be a very nice testing framework. For one, it stays away from using anything derived from Expect (i.e., DejaGnu) and has a way to extend examples with meta-data and results with which you may validate the output of an executed program.

With releasing this, my intention is that if it proves useful, that it be forked into a new project on Github. I will certainly entertain pull requests, but since I (unfortunately) am not doing anything with OpenMP these days, I might not have the time or motivation to maintain the project. I am happy to lend my Perl and shell scripting knowledge, if that could be of any help.

Thank you,
Brett Estrade

Thanks Brett for posting your useful tools. I'll make sure your link be aware by the ARB members or possibly be added in an OpenMP twiki page.
