* `-z,--blocking <0/1>` Make NCCL collective blocking, i.e. have CPUs wait and sync after each collective. Default : 0.
* `-G,--cudagraph <num graph launches>` Capture iterations as a CUDA graph and then replay specified number of times. Default : 0.
* `-C,--report_cputime <0/1>]` Report CPU time instead of latency. Default : 0.
* `-R,--local_register <1/0>` enable local buffer registration on send/recv buffers. Default : 0.
* `-R,--local_register <0/1/2> enable local (1) or symmetric (2) buffer registration on send/recv buffers. Default : 0.
* `-T,--timeout <time in seconds>` timeout each test after specified number of seconds. Default : disabled.
