Hi Julio, - Cost of the longest running local computation; We don't have this yet per superstep.
- Cost of global communication between the processors; We provide information on count/size in bytes of messages sent and received by peers.( IO_BYTES_READ, MESSAGE_BYTES_TRANSFERED, MESSAGE_BYTES_RECEIVED, TOTAL_MESSAGES_SENT, TOTAL_MESSAGES_RECEIVED, COMPRESSED_BYTES_SENT, COMPRESSED_BYTES_RECEIVED) - Cost of the barrier synchronisation at the end of the superstep. This is again provided in the final output in TIME_IN_SYNC_MS. The stats above are aggregated throughout the lifecycle and we don't have a breakdown per superstep yet. You may create a JIRA for tracking. Thanks, Suraj On Fri, Mar 15, 2013 at 8:10 PM, Edward J.
