Fibtest is a small C application that runs the Fibonacci sequence and reports how many iterations it completed.
It spawns fast threads and slow threads. Fast threads run the sequence as fast as possible. Slow threads run 100 iterations and then sleep for 10ms. Each thread is pinned to its corresponding CPU (thread 0 is on CPU 0, thread 2 on CPU 2 etc...).
By default fibtest spawns one fast thread on CPU 0 and a number of slow threads equal to the number of CPUs minus the number of fast threads.
$ ./runfibtest 1; ./runfibtest
runfibtest optionally takes an argument for the total number of threads to spawn. With no argument
it will spawn one fast thread and as many slow threads as are equal to one less than the total number of
CPUs.
It returns the number of iterations of the Fibonacci sequence it was able to accomplish as well as how long it was throttled and the corresponding CPU usage.
