(ops_completed / (time(NULL) - time_started)
I thought my new machine had a problem but it turned out to just be
running so fast that "time(NULL) - time_started" really was zero.
printf("\033[%d;%dH\033[32m%8ld\033[0m", row, col, ++ops);
++ops_completed; // this is declared "volatile" so we don't need to lock it
if (thread_id == 0) {
+ // FIXME the following line produces a divide by zero error on fast machines --- ↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓
printf("\033[2;55H\033[44m\033[33m\033[1m%ld ops/sec \033[0m", (ops_completed / (time(NULL) - time_started)));
}
fflush(stdout);
