This program has a typical master-worker structure:
if (i_am_the_master) {
<initialise the problem>;
<initialise workers>;
<send initial batch of the tasks to the workers>;
REPEAT {
<receive an answer from a worker>;
<send another task to the worker if the job is not finished>;
or
<send a termination signal to the worker if the job is done>;
} UNTIL <all workers are dead>;
}
else {
<receive initialisation from the master>;
REPEAT {
<receive a task from the master>;
<work on the task>;
<send the answer to the master>;
} UNTIL <terminated by the master>;
}
