As IBM continues to build new machines in its Blue Gene line of powerful supercomputers, the operating system of choice from now on will be Linux.
In an announcement this week, the company said the open-source Linux operating system was selected because it of fers flexibility and has a large base of and contributors to help solve challenges as they arise.
"We had two choices of operating systems for the Blue Gene family, either use a special purpose system or Linux," Bill Pulleyblank, director of Exploratory Server Systems at IBM Research, said in a statement. "We saw considerable advantage in using an operating system supported by [the] open-source community so that we can get their input and feedback."
Takako Yamakura, a spokesman for IBM Research, said the early focus in the Blue Gene project was on hardware. But as Blue Gene has evolved, the operating system has received more attention from engineers -- leading to the official designation by IBM of Linux as the operating system of choice.
The most recent addition to the Blue Gene family is the Blue Gene/L supercomputer being built jointly by IBM and the Lawrence Livermore National Laboratory for the U.S. Department of Energy's National Nuclear Security Administration (see story) . The machine, announced last November, will be at least 15 times faster and 15 times more power-efficient than today's fastest supercomputers, but will take up only one-fiftieth of the space.
The original Blue Gene supercomputer is expected to be completed by 2004 (see story), while Blue Gene/L is expected to be ready a year later
Blue Gene/L is expected to operate at about 200 trillion floating-point operations per second -- larger than the total computing power of the top 500 supercomputers in the world today, according to IBM. Blue Gene/L will also include IBM systems that allow complex computers to do self-repairing, self-managing and self-configuring, making them easier to manage and set up.
For IBM, the latest Blue Gene/L project is designed to demonstrate commercial uses for the powerful machines so the company can market that end of its research for additional sales.

October 25 2002
A critical vulnerability has been discovered in Kerberos which could allow attackers to circumvent the authentication system.
Kerberos is an authentication system which is designed to let two parties exchange private information across an otherwise open network.
It works by assigning a unique key to each user who logs on to the network. This key is then embedded in messages to identify the sender of the message.
The US Department of Energy's Computer Incident Advisory Capability warned that a stack buffer overflow existed in the implementation of the Kerberos v4 compatibility administration daemon (kadmind4) in the MIT krb5 distribution which allows connnections to systems running older versions of Kerberos.
The flaw could be exploited to gain unauthorised root access to the key distribution centre which does the authentication.
I also saw a an article about MSN. they put up their flyers and New York City Officials told them that it was illegal and that they will be fined. Also Microsoft has to take the flyers down immediatley. I think the fine is 50 dollars (It has
to be more than that) Also New York siad it makes the streets look dirty. Microsoft itself is dirty, so anything it touches is dirty. In fact, I am using windoze right now and I am feeling as dirty as an old used whore... A really old VD, AIDS, Hepatitis, red eye, smelly, athletes foot infected
whore.
