How to stop and restart execution of a socket programmatically

Hello, i have a sequence running in parallel mode with a series of subsequences and i wanted to do this:

once one of the 2 sockets encounters a certain subsequence (which has multiple instances) the other socket has to  wait for the execution of that subsequence to finish and execute only after.

i could probably do this overriding the pre step sequence of the parallel model but i dont know how to effectively do the waiting/stopping and starting.

Stupid question to start with.... if you have inter-socket dependencies like the one you describe, what is the reason you are not using the Batch Model instead of the Parallel Model?

i have to use the parallel model for other reasons.

OK, next step.

 

The thread title says stop and restart execution, the description implies that one execution has to wait for the an other one, so I'm concentrating on this.

 

Concept-wise, you might want to look into Synchronization using Rendezvous.

Yet there's a caveat to this: if you are running more than two sockets a Rendezvous become ambiguous. So you might give the semaphore a try.

 

Does your concrete use case refer to handling sth. like single hardware ressources?

 

I am very careful with recommending things without knowing a little more. I have gotten burnt in a Parallel Model Synchronization hell once...
