Parallel Program Construct - Computer Architecture

I'm not sure whether this is a correct place for me to ask, it's about Computer Architecture. But I'm desperate so please pardon me.

Does anyone understand this parallel program? I can't proceed to answer my assignment because of this.

It means that Proc_1 to Proc_k execute concurrently. For example, if each needs 2 seconds to be done, the total time to execute Proc_1 to Proc_k is 2 seconds, not 2*k seconds.

This means that each instruction between PARBEGIN and PAREND should be executed in parallel and the whole block will terminate when every single proc_k has terminated.

So in other words, the program will continue after PAREND as soon as proc_1 to proc_k (executed concurrently) terminated.
