Each possibly merged collective operation has a header entry which describes the collective operation as a whole. Use the plus button to get a detailed list of the same information per Process/Group. The exact processes or process groups shown depend on the current process aggregation.
This dialog box contains the following entries:
Entry: | Description: |

First Time | First time, one of the merged operations was entered. |
Last Time | Last time, one of the merged operations was left. |
Volume Sent | Number of bytes sent. It is the sum of all bytes sent on all merged operations for the per-process rows. The per-operation row sums up all per-process rows. |
Volume Received | Number of bytes received. It is the sum of all bytes received on all merged operations for the per-process rows. The per-operation row sums up all per-process rows. |
