NVIDIA Scalable Hierarchical Aggregation and Reduction Protocol (SHARP) Support
The following ibdiagnet options can be used to dump SHARP Trees configuration and SHARP traffic counters.
Parameter | Description |
--sharp | Collects SHARP Trees configuration and dump to ibdiagnet2.sharp & ibdiagnet2.sharp_an_info.
|
--sharp_control_version <0|1|2> | Checks and dumps only SHARP nodes with the specified version (default 0):
|
--sharp_opt <[csc][dsc][dscp][ ad_hoc]> | Comma separated SHARP options once "--sharp" option is selected:
|
Examples:
This example shows 3 level SHARP tree which root (rank 0) is Aggregation Node 0xec0d9a0300246f38.
