[CIG-LONG] cig-long email list

[Eunseo Choi]

Hi, Steve and Garrett

Since the issue at hand is performance, I agree with Garrett that we 
don't have to solve exactly the same problem for now.

The use of variable grid size should be fine in this test if the total 
problem size is kept constant.
The SNAC's input file I gave to Walter makes a regular grid.
