My HCA is ConnectX-3,and when I call ib_write_lat,what's the meaning of -C
option?
Because when I chose -C ,the t_avg of 1024 bytes is 8443 usec and 1GB is
2758537 usec,it's too long and I don't understand the parameter
-C(report-cycles
report times in cpu cycle units) meaning.
But when I cancel -C,the time becomes too short for 1024bytes etc,it's too
fast.
Can you solve this?
