How many cores are needed to demarcate “High Performance” these days?
I can remember when 32 cores meant you had a great deal of processing power. So what constitutes “High Performance” in your mind these days?
I would like to share an astute observation (first heard them from my good friends Steve Gombosi and Jeff Kuehn) – If it is to be classified as a “supercomputer” (or HPC) system, then it must be able to turn the older compute bound problem into an I/O bound problem!
So the number of cores do not matter, it is how you harness them together to achieve a quanta leap forward that makes it “HPC”
That’s a good one, tell Steve and Jeff I will have to “borrow” that quote. For some of what I am doing with retrograde analysis of endgames (finding very long checkmates in the game of chess and long wins in the game of checkers) I can become I/O bound very quickly with as few as 8 cores fully engaged. I am looking into making the process more parallelizeable, but I hit the Amadahl’s Law limit rather quickly because the I/O bound portion is inherently serial. Now if hard drives were only as fast as RAM, there would be no problem

Quant development: Massive Parallel Computing(20000 cores) Vs Small 1600core SMP Cluster
What information should be needed to ask so that you can make a reasoned assessment and recommendation between this two options?
By “SMP Cluster” do you really mean “cluster of SMPs” ? Or do you mean a single
shared memory address space for hundreds of processors?
If the latter, what systems are you considering and how would you program it?
Are you really trying to ask if multi-threading is better than message passing at this scale?FACEBOOK ACCOUNT and TWITTER. Don't worry as I don't post stupid cat videos or what I eat!
