Currently MPP's have COTS processors and specialized networks but this could reverse
-
Pervasive ATM will indeed lead to COTS Networks BUT
-
Current microprocessors are roughly near optimal in terms of megaflops per square meter of silicon BUT
-
As (explicit) parallelism shunned by modern microprocessor, silicon is used for wasteful speculative execution with expectation that future systems will move to 8 way functional parallelism.

Thus estimate that 250,000 transistors (excluding on chip cache) is optimal for performance per square mm of silicon
-
Modern microprocessor is around ten times this size
|

Again simplicity is optimal but this requires parallelism
|
| 4 |
Contrary trend is that memory dominates use of silicon and so performance per square mm of silicon is often not relevant
