Comparing Levels of Parallel Execution

CS 441 Lecture, Dr. Lawlor

We've talked about a bunch of different levels of parallelism in this course so far:
Each one of these levels of parallelism cascade into one another, so (hypothetically):
That's 200,000 cores; 800,000 threads; 3.2 million floats; or 25.6 million stages.  That's a lot of parallelism.  They're hoping to hit a dozen petaflops (12,000 trillion floating point operations per second), which they can get by finishing 3 million floating point operations per clock at a 4 GHz clock rate.
