perfSONAR User Q&A and Other Discussion

[Jay Packard <>]

Thanks for getting back so quickly, Jason.  Perl would definitely be 
helpful, but Java would be the most helpful.  Do you have a client 
written in Java?  I'll subscribe to the dev list. 

Dan, could you please tell me a little about the gridftp work you are 
doing in conjunction with Perfsonar?  I don't want to duplicate your 
work.  Perhaps I could assist in your work.  Are you actually starting 
test gridftp transfers or just monitoring an existing production 
system?  In the former case, I imagine something like BWCTL but for 
gridftp instead.

Thanks,
Jay
