Why is the Dept of Defense buying Sony PlayStation 3’s over IBM machines to build high performance computing clusters?
With respect to cell processors, a single 1U server configured with two 3.2GHz cell processors can cost up to $8K while two Sony PS3s cost approximately $600. Though a single 3.2 GHz cell processor can deliver over 200 GFLOPS, whereas the Sony PS3 configuration delivers approximately 150 GFLOPS, the approximately tenfold cost difference per GFLOP makes the Sony PS3 the only viable technology for HPC applications.
The U.S. Air Force is looking to buy 2,200 Sony (NYSE: SNE) PlayStation 3 game consoles to build out a research supercomputer, according to an document posted on the federal government’s procurement Web site. The PlayStation 3s will be used at the Air Force Research Laboratory’s information directorate in Rome, N.Y., where they will be added to
Why is the PS3 price point so attractive? For Sony, It’s all about the games – not the hardware. It’s all about the razors, not the handle.
Read about Linux Plug Computing – Linux in a box the size of a wall-wart power supply
Lots of technical doc and schematic on the website. Order a prototype and dev kit for $99
The SheevaPlug is a development platform, targeted for use as a plug computer, and designed to run network-based software services. It features a Kirkwood Series SoCwithan embedded Marvell Sheeva™ CPU core running at 1.2 GHz. This device connects to the network using GbE, offers desktop class performance, and can be used to replace a PC-based home server for many applications. Peripherals connect using the included USB 2.0 port.
The development kit is enclosed in a plastic case that also contains a universal power supply. For developers a USB-based debug connection is included to enable simple debuggingand reprogramming.
Learning about Linux – the easy way
Linux is seen as an alternative to Windows. So if you are one of those who does not want to be “assimilated into the collective” of Microsoft then maybe Linux is for you. If you are using a Mac then you are already a UNIX/Linix user – but may not know it.
Or perhaps you just want to keep up with the conversation – when the conversation turns to Linux.
If so, this posting is for you. This is a no-fuss, no-muss way to get your feet wet with Linux. This is so easy that “no excuses” – we take no prisioners.
If you read our article 50 Megabytes of Penguin Power and gave the DSL version of Linux a try and liked it, maybe you are ready to move up and give another Linux distribution a try.
Linux at Zero Risk – to your PC
Again, as in our previous posting, the goal is to make it as simple as possible to play with Linux and not put your existing operating system in any jeopardy. Here are the requirements:
- Get Linux up and running in a matter of minutes without frustration.
- No hard disk partitioning
- No changes to the way your system boots
- Get rid of Linux completely when you are done.
That seems a reasonable set of goals to achieve.
The Linux “Live CD” Concept
The solution is to get your hands on a Linux “Live CD”. A live CD for Linux is bootable version of Linux that runs completely off a combination of the CD and the RAM in your personal computer. You don’t need to install anything. What could be easier than that? Again, we are after the least frustrating way to play and learn about Linux.
A popular “fully loaded” (all the bells and whistles) distribution of Linux is Knoppix. Once you get your hands on Knoppix you have an extremely powerful Linux.
Here are some of the things you can do
- Use Open Office – an alternative to Microsoft Office.
- Browse the internet in a super safe way.
- Play DVD’s and CD’s
- Software development
- Access Windows Shares on your attached network
- Run a file server (NFS, Windows, etc)
- Run a Web Server – Apache – out of the box
- Run a database – mySQL
- Watch all the traffic on your network – WireShark
There is a ton more stuff you can do. There are even some exotic things you can do like use this Linux as a boot server to boot other PC’s over the network – more about that later.
How Knoppix is Distributed
Knoppix is distributed as an .ISO. An ISO is an image of a CD that exists as a file. An ISO is something that most CD/DVD burning software distributed with PC’s or purchased separately (or free) understand. Once downloaded, if you double-click on the .ISO file, your PC CD/DVD burning software should launch.
Getting Knoppix up and running
DSL – Damn Small Linux
By now you have probably heard about Linux. Maybe you wanted to try it out and see what it was all about. Then you found out that to install Linux you had to create a new partition on your hard disk, or buy a new hard disk, make a dual boot system, or otherwise disturb your beautiful MS Windows operating system. Then, if you got it installed how would you get if off your system when you were done playing with it? How would you get rid of the dual boot software – grub or lilo – and get the Microsoft boot blocks back on your hard disk?
Well heck, where there is a will there is a way.
