There are at least 3 issues in HPCC software
-
Fundamental problems in memory bandwidth/latency; data distribution and nifty parallel algorithms
-
Engineering implementation including scaling robust systems
-
Useability -- is the HPCC programming environment attractive and productive

|
We did well on "fundamental issues" but failed on "in principle" straightforward but costly engineering and User Interface areas
|
Petaflop initiative faces much harder (but probably soluble) fundamental issues but is bound to fail unless there is a strong (well enough funded) implementation program
-
Commercial motivation will generate insufficient funds!
