    I recently did a fresh install of Centos 7.3 and then the 
    perfsonar-tools bundle install.  I casually did a 'pscheduler --help' 
    just to confirm it was installed.  It was.  I of course then did a bunch 
    of 'bwctl' tests and then stopped myself and said try the 'new' thing.   
    I tried a pscheduler command line it failed with a particularly odd 
    error message.

    [preese@srn-dy6 ~]$ pscheduler task throughput --dest <local-host>
    Unable to find pScheduler on localhost

You’re one bundle too low on the totem pole.    Perfsonar-tools installs just 
the underlying tools (iperf3, owamp, etc.) and the pScheduler CLI, which will 
let you communicate with pScheduler on other systems.  Making your local 
system run tasks with pScheduler requires the pScheduler server, which is 
what does the work.  That’s included in perfsonar-testpoint (and, by 
extension, -core and -toolkit).  A yum install of the right bundle will get 
everything installed and started.

You can check to see if the server is running on a host with “pscheduler ping 
<hostname>” (which is different from measuring round-trip time with 
“pscheduler task rtt --dest <hostname>”).
