That was true of the non-Sun experimental architectures, like the Intel
432 and various VLIW machines. The Sun T machines ran ordinary SPARC
code without any changes or recompiling.
It very definitely wasn't for applications that already parallelized.
Our customers didn't have such things! Hadoop was almost unknown to them
I suspect Sun had already fallen off too many people's radar, and the
performance improvement didn't change anyone's minds.
