** The Linear Algebra Cube:
   dense vs. sparse; direct vs. iterative; linear system vs. eigenproblems
** Iterative vs. loop-based algorithms
** Linear algebra and HPC
** Top500, what is was, where it is going
** Time - what is wrong with it?
** Other performance metrics? Quality of an algorithm?
** How to relate to the potential of the architecture?
** TPP:
   Theoretical Peak Performance = frequency * #ops per cycle * #cores
** ALU, FPU, pipelining, latency vs. throughput
