I have been trying to find out, how can I set these below values, if I use Luster & LNET using 25 gbps Ethernet network. Seems like for Infiniband or Intel OPA, you can set them in ko2iblnd.conf.
tunables:
peer_timeout: 180
peer_credits: 8
peer_buffer_credits: 0
credits: 256
lnd tunables:
peercredits_hiw: 64
map_on_demand: 32
concurrent_sends: 256
fmr_pool_size: 2048
fmr_flush_trigger: 512
fmr_cache: 1
Also, I have been doing Dynamic Network Configuration using lnetctl command, in that case, is there a way to set the above values or it has to be via some config file only?
