# Currently it isn't possible to auto-tune the o2iblnd parameters optimally # inside the kernel since the OFED API hides the details from us. # Unfortunately, there isn't a single set of parameters that provide optimal # performance on different HCA/HFI types. This file provides optimized # tunables for the OPA cards. # # ** Please note that the below settings are the recommended settings only for # OPA cards. If other IB cards are also present along with OPA cards then # these settings will be applied across all the configured IB interfaces. # # Card detection and tunable selection is handled via /usr/sbin/ko2iblnd-probe # at runtime when the ko2iblnd module is installed, either at boot or when # Lustre is first mounted. alias ko2iblnd-opa ko2iblnd options ko2iblnd-opa peer_credits=32 peer_credits_hiw=16 credits=1024 concurrent_sends=64 ntx=2048 map_on_demand=256 fmr_pool_size=2048 fmr_flush_trigger=512 fmr_cache=1 conns_per_peer=4 install ko2iblnd /usr/sbin/ko2iblnd-probe
