Measure OS Thread to Thread synchronization latency.

How-It-Works:

The main thread spawns a thread B that will wait on condition variable and then sleep 10s Then, main thread stores rdtsc timestamp to beforeTicks and signals the condition variable. Later on, B wakes and immediately reads beforeTicks and gets final timestamp using rdtsc. Next, B exits the critical section and computes some stats on the timestamp difference.

I have implemented buzy-waiting in main thread to improve test accuracy.

How-To-Build:

Just run make in the project directory: $ make

How-To-Use-It:

First argument is the main thread affinity passed directly into pthread_setaffinity_np. Second argument is the second thread's affinity. $ ./testrw 1 3
