Sortbench is a CPU benchmark.
The test does on purpose not use the fastest possible sort,
but uses an algorithm which stresses certain parts of the CPU.

The testcase stresses the following CPU features:
1) Data-Cache
2) Branch Prediction / Conditional Code Execution (IF THEN)
3) Loop Performance
4) Memory Hazard Detection 
   The test does not generate a Hazard.
   But the test does mixed read/write operations to the same Data Cache line.
   This is a typical behaviour for a program working with the stack.


To run the test please compile like
 
gcc -o sortbench -O2 sortbench.c


The sourcecode is free to use.

Have fun!
