Today we see the standard trade-off between
-
Memory Hierarchy as in a Shared Memory SGI Power Challenge
-
Distributed Memory as in IBM SP-2
-
And indeed a merging of these ideas with Distributed Shared Memory

Most people believe that it is easier to manage hierarchy (in an "automatic" fashion as in a compiler) than it is to manage distributed memory
|
| 3 |
PIM gives us a classic distributed memory system as base design where as most other proposals (including Superconducting) give a shared memory as base design with hierarchy as issue.
-
Will increased memory hierarchy make its management so much harder so that trade off will change ?
-
Management of year 2005 distributed memory does not get much harder from systems we are familiar with today?
