- A debate is occuring at my site (and within my mind) regarding 64 bit
- versus 32 bit computing.
-
- I'm trying to figure out why I want to go to a 64 bit machine Alpha
- AXP system instead of continuing to run 32 bit machines (RS6K, Sun).
-
- Outside of the numerical analysis issues, the only other issues I see
- are:
-
- 1. 64 bit ints allow the easy support of files larger than 2 Gbytes.
-
- 2. 64 bit ints allow the construction of filesystems larger than 2
- Gbytes.
-
- I do know some vendors (convex) have addressed these issues within a
- 32 bit architecture; Sun allows >2GB filesystems, if memory serves.
- Have I missed any other obvious (or not!) programming or system
- administration issues?
