Linpack Benchmark
=================
 + test flop performance
 + http://www.netlib.org/benchmark/hpl/
 + http://www.top500.org/lists/
 + MATLAB Version: http://people.sc.fsu.edu/~jburkardt/m_src/linpack_bench_backslash/linpack_bench_backslash.html
 + http://www.top500.org/project/top500_description/
      # Proc. - Number of processors (Cores)
      # Rmax  - Maximal LINPACK performance achieved
      # Rpeak - Theoretical peak performance
      # Nmax  - Problem size for achieving Rmax
      # N1/2  - Problem size for achieving half of Rmax


STREAM Benchmark
================
 + stresses memory bandwidth
