Github user harshach commented on the issue: https://github.com/apache/storm/pull/2241 @HeartSaVioR Its not 12 executors per worker. If you don't pass a command-line argument, it sets parallelism variable here to 4 https://github.com/apache/storm/blob/master/examples/storm-starter/src/jvm/org/apache/storm/starter/ThroughputVsLatency.java#L277 and multiplys with 4 here again https://github.com/apache/storm/blob/master/examples/storm-starter/src/jvm/org/apache/storm/starter/ThroughputVsLatency.java#L359 . So setting a parallelism unit 16 per component. This is nothing to do with how many workers you've.
