Running NVIDIA SHARP Aggregation Manager (AM) Daemons

1.0
Note

As of NVIDIA SHARP version 2.7.0, sharpd daemon no longer exists. sharpd-related activity is now performed from the user-application process instead.

This section describes how to install Aggregation Manager in the fabric using NVIDIA SHARP AM daemon script.

NVIDIA SHARP Aggregation Manager daemon (sharp_am) is executed on a dedicated server along with the Subnet Manager.

Installing Aggregation Manager as a service is required when used from the HPC-X or from MLNX_OFED packages.

In order to install/remove NVIDIA SHARP AM daemons, use sharp_daemons_setup.sh script provided with the NVIDIA SHARP package. For example:

Copy
Copied!
            

$HPCX_SHARP_DIR/sbin/sharp_daemons_setup.sh   Usage: sharp_daemons_setup.sh (-s | -r) [-p SHARP location dir] -d <sharpd | sharp_am> [-m] -s - Setup SHARP daemon -r - Remove SHARP daemon -p - Path to alternative SHARP location dir -d - Daemon name (sharp_am) -b - Enable socket based activation of the service

  1. Run the following as root:

    Copy
    Copied!
                

    # $HPCX_SHARP_DIR/sbin/sharp_daemons_setup.sh -s -d sharp_am

    Daemon's log location is: /var/log/sharp_am.log

  2. Set the "run level".

  3. Start sharp_am as root.

    Copy
    Copied!
                

    # service sharp_am start

To remove sharp_am, run the following on the AM host:

Copy
Copied!
            

# $HPCX_SHARP_DIR/sbin/sharp_daemons_setup.sh -r -d sharp_am

Upgrading SHARP AM daemons requires their removal and re-registration as instructed in the sections above.
