Yep. We've historically had a lot of CPUs or multi-cpu machines that were good for running "embarassingly parallel" loads but wasted capacity for general purpouse use, a bit like this one! More hw threads or cores has traditionally not been good news from software POV. This kind of machine is nice to look at from afar but for most apps trying to get anywhere near a 64 fold speedup on your application on this would mean scrapping the code base and doing 1 failed rewrite, followed by 1 marginally successful one, taking up ruinous amounts of calendar time and engineering resources. But of course it's diferent now than in 2005, because today we can't do any better.
