Here the case for special purpose machines is less compelling than for GRAPE as QCD is "just" regular (easy to parallelize; lowish communication) and extremely floating point intensive. |
We illustrate with two machines which are classic MIMD distributed memory architecture with optimized nodes/communication networks |
