Where do "commodity clusters" stop and real supercomputers start? Find out Wednesday in San Jose, California.

Moshe Bar, the project manager of openMosix, is scheduled to speak at the Silicon Valley Linux Users Group meeting on Wednesday, February 5, 2002. The meeting will be held at Cisco Systems in San Jose, California, at 7PM.

As clusters are expanding from high performance computing into business applications, single-system-image clusters quickly are gaining importance. In a short time period, openMosix has gained thousands of installations around the world and enjoys an enthusiastic and strong developer community. In this talk Moshe Bar will explore the internals of openMosix, the technology's application fields and sample uses.

openMosix is a kernel patch and does not require changes to user space applications. Once you have installed openMosix, the nodes in the cluster talk to one another, and the cluster adapts itself to the workload. Processes originating from any one node, if that node is too busy compared to others, can migrate to any other node. openMosix continuously attempts to optimize the resource allocation.

Because all openMosix extensions are inside the kernel, every Linux application automatically and transparently benefits from the distributed computing concept of openMosix. The cluster behaves much as does a symmetric multiprocessor, but this solution scales to well over a thousand nodes, which can themselves be SMPs.

Moshe Bar is the former co-project manager of MOSIX and the current project manager of openMosix. He has authored several books on the Linux kernel and clustering and is co-author with Karl Fogel in the classic CVS book OpenSource Development with CVS. Moshe has been a senior monthly columnist at BYTE for the last four years and wrote regular kernel columns in the past for Linux Journal and other publications. In 2001 Moshe Bar became CTO of Linux clustering start-up Qlusters, Inc. Moshe has a M.Sc and Ph.D. in computer science and teaches advanced operating systems topics at Tel Aviv University and at the United Nations Atomic Agency research institute ICTP in Triest, Italy. He also is a permanent researcher at the Italian National Institute of Particle Physics.

SVLUG meetings are free and open to the public.

SVLUG also organizes monthly installfests on the third Saturday of every month.

Re: openMosix Security?

On February 3rd, 2003 Anonymous says:

What good is OpenMosix if there is no security?

The faq or questions in the forum were answered that this application must be firewalled off from internet. Yet more and more computers and lans are being connected to the internet. With the chance of a misconfiguration or breech, who in their right mind would run this unless you need if for scientific research? Yet it is being billed as something that could be used from everything from sliced bread to swiss cheese.

Nice concept if you have the extra hardware to throw at it that can be isolated from the internet. Or if you can wait for the "feature" of security to be added to it. But as we see story after story of security breeches, and of computers that were connected to the internet that shouldn't have been, this is a disaster after disaster waiting to happen.

News Flash: Linux Kernel 3.0 to include an on-the-go Expresso machine interface! Ok, maybe not, but Linux is definitely going mobile, from phones to e-readers. Find out more inside about Android, the Kindle 2, the Western Digital MyBook II, The Bug, and Indamixx (a portable recording studio). And if you've gone mobile and you been wanting more Emacs in your life then check out Conkeror.


To compliment the mobile we've got the stationary: parsing command line options with getopt, checking your Ruby code with metric_fu, and building a secure Squid proxy. How is this stationary you ask? What can we say? It's not. We just wanted to see if anybody actually read this part of the page :) .


All this and more, and all you have to do is get your hot sweaty hands on the latest copy of Linux Journal.
