[Swift-devel] Re: Swift jobs on UC/ANL TG

[Ti Leggett]

Also, it looks like you're using a local project and not a TG project.  
We are not able to report this usage to NSF because it counts against  
our discretionary usage. Do you have a TG project? If not can you  
request a DACC allocation to use?
