	APE: the basic ideas	Schifano S. Fabio - INFN

From the application requirements we gain the following architectural requirements:

SIMD/SPMD architecture: each node of the machine run the same program on a different data
NO harware/software support for load balancing
monstly first neighbour communication patterns are needed
the nodes of the machine can be arranged on a 3D-MESH
the nodes must perform complex operations

Design constraints:

No hardware cache handling ==> ARE HARD TO IMPLEMENT IN HARDWARE
No dynamic instruction scheduling

No hardware cache handling	==> ARE HARD TO IMPLEMENT IN HARDWARE
No dynamic instruction scheduling

make APE an unusual computer but easy to build.
