Within srpt on the array I have options ib_srpt srp_max_req_size=4148
On the client I also only have options ib_srpt srp_max_req_size=4148
I have not tuned srp_sq_size as I was only aware of
parm: srp_max_req_size:Maximum size of SRP request messages in bytes. (int)
parm: srpt_srq_size:Shared receive queue (SRQ) size. (int)
parm: srpt_service_guid:Using this value for ioc_guid, id_ext, and cm_listen_id instead of using the node_guid of the first HCA.
Please explain what that does.
Hello Laurence,
The srp_sq_size parameter controls the send queue size per RDMA channel.
The default value of this parameter is 4096. I think this is the
parameter that has to be increased to avoid hitting "IB send queue full"
errors.
Bart.
