Tips for Avoiding Deadlocks

• Use lots of echo statements.
• Use barrier IDs.
• Do not execute barriers remotely (e.g., barrier@all).
• Remember that step usually does an implicit barrier.
• Have each node do its own step command, or have one controlling node do a step@all. (similarly for reset)
• Do not use the stop command.
• Keep things simple.
