This is the benchmarking code that was used in this Stackoverflow question: http://stackoverflow.com/q/22684123/1128289

The benchmark is run by sourcing the file test_all.sh. Running the benchmark requires g++ 4.8 and icc. The script also plots and summarizes the results. For this R and ggplot2 are required.

The directory output contains the contents of the directory for me after sourcing test_all.sh.

The benchmark produces a curious result. Code produced by icc seems to be slower when allocating memory using malloc() compared to new.

Elapsed clock cycles for allocating a char array with 16000 elements:
