Take a look at Limulus systems from Basement Supercomputing: http://www.basement-supercompu...

These are fast low power/noise/heat systems with a fully installed open source HPC software stack.

You can't cheat Amdahl's law anymore than you can give birth in one month with nine women. The law is a rather simple idea similar to chemical kinetics, when you think about it. i.e. a rate limiting steps.

If you are interested in a non-mathematical description of Amdahl's law have a look at http://www.clustermonkey.net/Parallel-Programming/parallel-computing-101-the-lawnmower-law.html

For those who would like a gentle introduction to quantum computing take a look at: A Smidgen of Quantum Computing

You may be thinking of this (Limulus Project)

Have a look at The Limulus Project. You will be able to buy one of these real soon.

Been there done that, maybe want to consult Linux Cluster Urban Legends before you continue down this path

Proof of concepts are nice, but when the GPU is firmly planted in the CPU, this will make more sense. The PCI bus can be a bottleneck in these types of situations. AMD fusion is a great example of this idea.

That is the point of the free version. How else do you get people to read and talk about your book in the sea of crap. If it is worth reading it will get noticed because there is no cost barrier. Those, like me that want bound versions of good books will pay for the paper.

Many people first used Windows not by choice, but by mandate -- there was no other option and the Microsoft monopoly made sure it stayed that way. (unless you bought a Mac) My guess is many people have found the MS experience frustrating and a general PITA, but there was never any other choice. They had to live with the shoddy time wasting experience Microsoft called computing.

Now given the option of having their "desktop experience" on their "phone" or "pad" I am sure many people are interested in real alternatives. My prediction is no matter how hard Microsoft tries to play the "we are the future of computing because we invented everything" song and dance, most users will chose iOS and Android for exactly that reason. Hi-tech karma at its best.

Forgot this link! Why Linux On Clusters?

The reasons Linux is so successful on HPC clusters are numerous. Historically, Linux was the best solution for many reasons. In particular, HPC clearly demonstrates why "open" is superior to closed approaches to a markt.

Here are some numbers from a post I made last week.
