Changes and New Features
High Availability in sharp_am Network Interfaces
sharp_am leverages multiple network interfaces of the management host to provide high availability in case of a network interface failure.
For further information, please see sharp_am Network Interfaces.
Added support for SHARP to leverage reliable multicast option with NVIDIA Quantum-2.
Removed support for reading sm data by a client application. The API functions sharp_request_sm_data, sharp_get_sm_data_buf_len, and sharp_get_sm_data have been removed and can no longer be used.
In addition, the configuration parameter ftree_ca_order_file is ignored in sharp_am.
