Think about these questions.
Why have machine cycle speeds stopped increasing?
What architectures do the top 3 machines on the Top 500 list use?
Which one of the following 4 choices are most GPUs: SISD, SIMD, MISD, MIMD.
Which one of the following 4 choices are most current multicore CPUs: SISD, SIMD, MISD, MIMD.
Per Amdahl's law, if a program is 10% sequential and 90% parallelizable, what is the max speed up that can be obtained with an infinite number of parallel processors?
4 Recently obsoleted parallel tech
Intel Xeon Phi
IBM BlueGene
5 My research
I do parallel geometry algorithms on large problems for CAD and GIS. See my home page. If this is interesting, talk to me. Maybe you can do something that leads to a jointly-authored paper.
