Thanks.
I can't say I'm an expert yet. But the more and more I read about highly optimized code on any platform, the more and more I realize that 90% of the problem is dealing with memory.
Virtually every optimization guide or highly-optimized code tutorial spends an enormous amount of time discussing memory problems. It seems like memory bandwidth is the singular thing that HPC coders think about the most.
