If you put your ASCII art inside
it will come out like you were expecting.
Unless you've got enough cores to have one free for each and every individual client, they literally can't execute simultaneously. By necessity, they take turns. Hopefully that doesn't matter to you.
I presume you're making the threads wait with something like usleep() ? Remember that sleep, usleep, etc may wait more or less time than you were expecting -- and that sleeping two minutes won't make you run every 2 minutes, since the rest your code takes a little time to run too. You should check gettimeofday() to see how long you need to rest. You should also give each thread an identical starting number to measure against, so they're all aiming for the same 2-minute mark.
A better way to do this would be for the app server to signal your clients with a mutex, semaphore, cond, or the like every time two minutes, and have the server tell them when they were supposed to have been woken up.
