[Swift-devel] MolDyn at Purdue

[Ioan Raicu]

Right, so if we want to get roughly the same execution time of 77 
minutes, we would need 34*20 = 680 machines for 2 hours, right?  If we 
halve the machine numbers, we can double the time reservation, right?

Let me know if you need help with the Falkon settings!
