run ocaml gen.ml to generate a performance test for bsb
The test involves the generation of DR * DC directories, the "directory matrix", and each directory contains MR * MC modules, the "module matrix". The module in row r and column c of the module matrix depends on all modules in the previous row of the same directory. The first row of modules in a directory depends on all modules in the preceding row of directories.
The test setup also permits a lot of parallelism for actually executing the rules: the modules in the same row can be compiled in parallel, as well as the directories in the same row.
Every module includes a big comment, so that the size of the files is not super-small.
To test it:
ocaml unix.cma gen.ml -n 4 test
cd test && npm install rescript && time ./node_modules/rescript/{your-platform}/rescript.exe
