Submission + - NASA to build largest Supercomputer ever (linuxworld.com.au) 1

Submitted by Onlyodin
Onlyodin writes: The National Aeronautics and Space Administration (NASA) has given the green light to a project that will build the largest ever supercomputer based on Silicon Graphics' (SGI) 512-processor Altix computers.

Called Project Columbia and costing around $160-million, the 10,240-processor system will be used by researchers at the Advanced Supercomputing Facility at NASA's Ames Research Center in Moffett Field, California.

What makes Project Columbia unique is the size of the multiprocessor Linux systems, or nodes, that it clusters together. It is common for supercomputers to be built of thousands of two-processor nodes, but the Ames system uses SGI's NUMAlink switching technology and ProPack Linux operating system enhancements to connect 512-processor nodes, each of which will have more than 1,000G bytes of memory.

The Digital Bedouins and the Backpack Office 149

Posted by Zonk from the natural-extension-of-flextime dept.
PetManimal writes "The laptop and wireless revolutions have led to the rise of a new class of digital 'Bedouins' — tech workers who ply their crafts from Starbucks and other locations with WiFi access. Another article describes some strategies and tools for embracing the Bedouin way of life, and even having fun: 'If you have the right kind of job, you can take vacations while you're on the clock. In other words, you can travel for fun and adventure and keep on working. You can travel a lot more without needing more official vacation time. I've done it. In August I took a month long vacation to Central America, backpacking from one Mayan ruin to the next, and I never officially took time off. I submitted my columns, provided reports and other input, participated in conference calls and interacted via e-mail. I used hotel Wi-Fi connections and local cybercafes to communicate and Skype to make business calls. Nobody knew I was sunburned, drinking from a coconut and listening to howler monkeys as I replied to their e-mails.'"
