1 # Currently it isn't possible to auto-tune the o2iblnd parameters optimally
2 # inside the kernel since the OFED API hides the details from us.
3 # Unfortunately, there isn't a single set of parameters that provide optimal
4 # performance on different HCA/HFI types. This file provides optimized
5 # tunables for the OPA cards.
7 # ** Please note that the below settings are the recommended settings only for
8 # OPA cards. If other IB cards are also present along with OPA cards then
9 # these settings will be applied across all the configured IB interfaces.
11 # Card detection and tunable selection is handled via /usr/sbin/ko2iblnd-probe
12 # at runtime when the ko2iblnd module is installed, either at boot or when
13 # Lustre is first mounted.
