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.
