EG is simply a client to SAS, and we would expect SAS to do the heavy lifting in terms of data manipulation and computations.
EG can work with a 64-bit version of SAS, even though the EG application itself is 32-bit.
Someday in the not-too-distant-future, we will probably have a 64-bit version of EG since that's definitely where the technology trends are taking us. But we do not have a firm timetable for that work.
