[Halld-offline] Fwd: Re: Data Challenge Meeting Minutes, January 31, 2014

[Sean Dobbs]

Dear all,

Has there ever been any discussion of running an XrootD service at JLab?
 It is an increasingly popular service for accessing data over the grid
these days.

BTW, I've used Globus Online on the desktop at a workshop before, and it
was really easy - about as hard as setting up Dropbox or a similar service.


Cheers,
Sean
