Comment: Understanding Amdahl's law (Score 2) 54

by deadline (#44048563) Attached to: Revisiting Amdahl's Law

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

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.

by deadline (#32524280) Attached to: MINI-ITX and the Future of PC Case Design?
I just wrote and article Low Cost/Power HPC using Atom processors and Mini-ITX boards. The first table is rather interesting (HPC = High Performance Computing):

The Nehalem Xeon runs 1.8 times faster, generates 7.3 times as much heat and costs 22 times as much as the D510 Atom. The performance is 7.7 times faster, but when you factor in the price-to-performance the Atom is 3 times better than the Xeon solution. Interestingly, the TDP/performance ratios are almost identical for both processors.

People will buy anything that's one to a customer.
