perfSONAR User Q&A and Other Discussion

[Doug Southworth <>]

Greetings all,

--parallel is the flag you need, but you'll also need to specify iperf2 as the tool since iperf3 is the default. So, your command would look something like:

$ pscheduler task --tool iperf2 throughput --dest foo.bar --parallel 2 (or more, if you want more streams)

Cheers,

Doug Southworth

Hi

I can't find how to run a parallel throughput test. 
I know there is a special key in iperf2 --dualtest for parallel test, but I can't find a use for perfsonar.

Hi Kirill,

I think you're looking for "--parallel" option for pscheduler.

$ pscheduler task throughput --dest foo.bar --parallel 2

in pSConfig file use "parallel: <number_of_streams>" in tests spec

Please note that iperf3 is single-threaded
