When the application is running, we can use the following method to view the port traffic information of the hca nic: 1) Clear the status of the port in use. Assume that the port is port1.# Cd/proc/IBA/mt23108/1/port1/# Echo> stats2) run the application3) Check the status of port1 and run the following command:# Cat/proc/IBA/mt23108/1/port1/statsOr directly use the command "p1stats" In addition, we can
