Detailed Attributes of Collective Operation Events
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:
|Name/Process||On the per-operation row this column lists the name of the selected operation (Mixed if different operation types were merged). On per-process rows it shows the name of the Process/Group.|
|Duration||Last Time minus First Time|
|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.|
|Count||Number of collective operations that are merged into the selection.|
|Root||The root process.|
|Communicator Name||The name of the MPI communicator on which the collective operation(s) was (were) executed.|
|Communicator ID||The plain ID of the MPI communicator on which the collective operation(s) was (were) executed.|
