A Cluster by Any Other Name Is Not a Grid

Filed under
Linux

Have you noticed how lately, when the conversation turns to distributed computing, grid and cluster are used as synonyms? These two words do have different meanings, Donald Becker reminds us.

So-called grid computing solutions for small to midsize businesses are more likely to be utility computing or clustering solutions, Becker says. A grid implementation is much more difficult. The only place for "true grid," he says, is with global enterprises that have a single point of administration for the CIO.

Becker knows whereof he speaks. While working at NASA's Goddard Space Flight Center during the late 1980s, Becker created the first Beowulf cluster, using software to connect many inexpensive PCs to solve complex math problems typically reserved for classic supercomputers.

Beowulf is a trademark controlled by Linux International.

Becker literally wrote-or rather co-wrote-the book on Beowulf Clustering: How to Build a Beowulf: A Guide to the Implementation and Application of PC Clusters.

Full Story.

Head 2 Head: Android OS vs. Chrome OS

A large part of Google’s OS success hasn’t been because of its awesomeness. No. Frankly, we think nothing speaks louder than the almighty dollar in this world. But both are “free,” right? So this is tie? Not really. Although Android is technically free since Google doesn’t charge device makers for it, there are costs associated with getting devices “certified.” Oh, yeah, and then there’s Apple and Microsoft, both of which get healthy payouts from device makers through patent lawsuits. Microsoft reportedly makes far more from Android sales than Windows Phone sales. You just generally don’t see the price because it’s abstracted by carriers. Chrome OS, on the other hand, actually is pretty much free. A top-ofthe-line Chromebook is $280, while a top-of-the-line Android phone full retail is usually $600. We’re giving this one to Chrome OS because if it’s generally cheaper for the builder, it’s cheaper for you. Read more
