Step 4. Reboot the machine if the installation script performed firmware updates to your network

adapter hardware. Otherwise, restart the driver by running:

"/etc/init.d/openibd

restart"

Note: The script adds the following lines to /etc/security/limits.conf for the user-

space components such as MPI:

* soft memlock unlimited

* hard memlock unlimited

These settings set the amount of memory that can be pinned by a user space application to

unlimited. If desired, tune the value unlimited to a specific amount of RAM.

Note: For your machine to be part of the InfiniBand/VPI fabric, a Subnet Manager must be

running on one of the fabric nodes. At this point, Mellanox OFED for Linux has

already installed the OpenSM Subnet Manager on your machine. For details on start-

ing OpenSM, see Chapter 8, “OpenSM – Subnet Manager”.

Step 5. (InfiniBand only) Run the hca_self_test.ofed utility to verify whether or not the

InfiniBand link is up. The utility also checks for and displays additional information such as

• HCA firmware version

• Kernel architecture
