Description
I would like to get information of all the collective operation rather top 20 shown in "Aggregate Collective Time" table. Is it possible to define any such env variable at runtime or change in the code to enable this information?
eg.
```
---------------------------------------------------------------------------
@--- Aggregate Collective Time (top twenty, descending) -------------------
---------------------------------------------------------------------------
Call MPI Time % Comm Size Data Size
Allreduce 4.08 256 - 511 8 - 15
Allreduce 2.31 256 - 511 0 - 7
Barrier 0.0468 256 - 511 0 - 7
Bcast 0.0343 256 - 511 512 - 1023
```

Research direction
Start by locating the code that produces the “Aggregate Collective Time” report and enforces the “top twenty” limit. Determine whether runtime configuration can control that limit or whether the report needs a code change; done means the report exposes all collective-operation entries as requested.
