[FLASH-USERS] ifort compilation problem

[Samuel Friedman]

Hi Latif,

These memory issues come from the fact that you're trying to put too many 
variables into memory.  Somehow the compiler knows/cares about this.  My 
notes say for me to use smaller blocks instead of larger blocks.  What are 
the size blocks you are using for UG?  My notes say that 128^3 blocks 
worked better than 256^3 blocks.
