Force all nodes to quit when exception happens in one program

[wcarvalho]

Hello, is there a way to get all nodes to stop when one node gets an exception?

Depending on the runtime you use - for "multi-threaded" execution entire program terminates due to exception.
When you use multi-process with outputting to files you can call wait() on the result of lp.launch() call.

Can you explain what "outputting to files" does? Also, somewhat unrelated, can you give advice on scheduling programs to launch one after the other? E.g., when one fails/exits, another program starts

[qstanczyk]

outputting to files writes output of each node to a log file. wait() can be used in any multi-process experiment and it can be used to schedule mulitple programs to execute one after the other.
