perfSONAR User Q&A and Other Discussion

[Verena Venus <>]

Hi Christian, all

The BWCTL plugin for perfsonarUI was written by Roland Karch, who is in 
vacation at the moment. Unfortunately, I'm not familiar with his code, so I'm 
not sure, if I can help. 

Good to know that the BWCTL MP is working :)

If you can give me some feedback concerning the installation procedure, 
especially what problems you were experiencing, I would be happy.

Kind regards,
Verena
