Safety in numbers -- a cloud-based immune system for computers

27.01.2010
A new approach for managing bugs in computer software has been developed by a team led by Prof. George Candea at EPFL. The latest version of Dimmunix, available for free download, enables entire networks of computers to cooperate in order to collectively avoid the manifestations of bugs in software.

A new IT tool, developed by the Dependable Systems Lab at EPFL in Switzerland, called "Dimmunix," enables programs to avoid future recurrences of bugs without any assistance from users or programmers.

The approach, termed "failure immunity," starts working the first time a bug occurs - it saves a signature of the bug, then observes how the computer reacts, and records a trace. When the bug is about to manifest again, Dimmunix uses these traces to rec-ognize the bug and automatically alters the execution so the program continues to run smooth-ly. With Dimmunix, your Web browser learns how to avoid freezing a second time when bugs associated with, for example, plug-ins occur. Going a step further, the latest version uses cloud computing technology to take advantage of networks and thereby inoculating entire communities of computers.

"Dimmunix could be compared to a human immune system. Once the body is infected, its immune system develops antibodies. Subsequently, when the immune system encounters the same pathogen once again, the body recognizes it and knows how to effectively fight the ill-ness," explains George Candea, director of Dependable Systems Lab, where the new tool has been developed. The young Romanian professor received his PhD in computer science from Stanford University in 2005 and his BS (1997) and MEng (1998) in computer science from the Massachusetts Institute of Technology.

The latest version, released online at the end of December (http://dimmunix.epfl.ch/), leverag-es the network. Based on the principle of cloud computing, all computers participating in the Dimmunix application community benefit from vaccines automatically produced whenever the first manifestation of a given bug within that community. This new version of Dimmunix is able to safely protect programs from bugs, even in un-trusted environments such as the In-ternet.

For the moment meant primarily for computer programmers, Dimmunix works for all widely-used programs used by private individuals and by companies. It is useful for programs written in Java and C/C++; it has been demonstrated on real software systems (JBoss, MySQL, Acti-veMQ, Apache, httpd, JDBC, Java JDK, and Limewire).

Im Focus: Scientists present new observations to understand the phase transition in quantum chromodynamics

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.

This is a joint press release of University Muenster and Heidelberg as well as the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt.

Then, in a phase transition, they combined and formed hadrons, among them the building blocks of atomic nuclei, protons and neutrons. In the current issue of...

Im Focus: Patented nanostructure for solar cells: Rough optics, smooth surface

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.

"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...

Im Focus: New soft coral species discovered in Panama

A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.

Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
