# 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, so this file provides optimized # tunables based on the installed IB interface cards. # # 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=128 peer_credits_hiw=64 credits=1024 concurrent_sends=256 ntx=2048 map_on_demand=32 fmr_pool_size=2048 fmr_flush_trigger=512 fmr_cache=1 conns_per_peer=4 install ko2iblnd /usr/sbin/ko2iblnd-probe
