History
Gael Guennebaud 0212eec23f simplify and optimize block sizes computation for matrix products. They 
are now automatically computed from the L1 and L2 cache sizes which are
themselves automatically determined at runtime.

README.txt 

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:
