This folder contains a couple of benchmark utities and Eigen benchmarks.
****************************
* bench_multi_compilers.sh *
****************************
This script allows to run a benchmark on a set of different compilers/compiler options.
It takes two arguments:
- a file defining the list of the compilers with their options
- the .cpp file of the benchmark
Examples:
$ ./bench_multi_compilers.sh basicbench.cxxlist basicbenchmark.cpp
