• If your kernel version does not match with any of the offered pre-built RPMs, you can
add your kernel version by using the
“mlnx_add_kernel_support.sh”
script located
inside the MLNX_OFED package.
The
“mlnx_add_kernel_support.sh”
script can be executed directly from the mlnxofedinstall
script. For further information, please see
'--add-kernel-support'
option below.
Example
The following command will create a MLNX_OFED_LINUX ISO image for RedHat 6.3 under
the /tmp directory.
• The script adds the following lines to
/etc/security/limits.conf
for the userspace
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.
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 the list of installation options, run:
./mlnxofedinstall --h
On Redhat and SLES distributions with errata kernel installed there is no need to use the
mlnx_add_kernel_support.sh script. The regular installation can be performed and weak-
updates mechanism will create symbolic links to the MLNX_OFED kernel modules.
On Ubuntu and Debian distributions drivers installation use Dynamic Kernel Module
Support (DKMS) framework. Thus, the drivers' compilation will take place on the host
during MLNX_OFED installation.
Therefore, using
"mlnx_add_kernel_support.sh"
is irrelevant on Ubuntu and
Debian distributions.
