[Swift-devel] [Fwd: Re: [Dsl-seminar] "Towards Loosely-Coupled Programming on Petascale Systems"]

[Ioan Raicu]

Hi all,
I just thought this talk might be interesting to the Swift and Falkon 
community, feel free to come by today at 4:30PM in RI405 at UChicago for 
the talk.  Also, sorry for the short notice, especially if you aren't on 
the UChicago campus.

Ioan

Hi all,
This is just a friendly reminder for today's seminar, that will take 
place at 4:30PM in RI405. 

See you at the seminar,
Ioan

PS: We'll be having some pizza today, instead of the usual chips and 
cookies :)
