No, you do not need a gLS to run the scheduled tests. When you setup your 
tests via the toolkit GUI, if you are able to contact the LSes, you will have 
the ability to browse the list of hosts out there and add them to your test 
set by clicking on them. If its not there, really all you lose is this 
browsing ability. You can still manually add the hosts to which you want to 
test. If you go to the link 
http://code.google.com/p/perfsonar-ps/wiki/pSPerformanceToolkit322#Scheduled_BWCTL,
 you will see a few screenshots down how to manually enter a host. Basically 
if you click "Scheduled tests" on the left menu, then click the "Add new 
throughput test", enter the test parameters, on the page that loads there is 
a button on the middle of the page called "Add new host". Click that and 
enter your private hosts in the pop-up. It should setup all your tests.

As I said in your response to question #1, you don't actually need a gLS to 
run the tests. If you are interested in bringing up an LS, I can get you an 
RPM when the new one is ready. You should be able to setup tests without one 
though.

Thanks,
Andy
