The following are the chart attributes you can set when plotting data for Functions. These attributes can be selected for the X Axis, Y Axis, and Metric.
Time (range) - The range of times from entry to exit of a function
Entry Time - The time when a function is called
Exit Time - The time when a function returns to the caller
Duration - The time difference between function entry and function exit
Process - The MPI global ranks in numerical order. Each function call has a unique process rank associated with it.
Function - The MPI function called.
Send Bytes - Number of bytes sent in an MPI function call
Receive Bytes - Number of bytes received in an MPI function call
1 (only for Metric) - Specifying 1 as the metric simply specifies an attribute whose value is always 1. This can be used to count data records or signal the presence or absence of data. For example, to count the number of function calls for each function, set Y Axis: Function, Metric: 1, Operation: Sum. To detect whether any function calls were made, set Operation: Maximum.
