K42

The core of K42 is based on the University of Toronto's operating system Tornado. K42 is the university's third generation of research on scalable operating systems. Tornado OS on a nuMachine Multiprocessor was the second generation and Hurricane OS on a Hector Multiprocessor was the first generation. ==Features==

K42 supports the Linux PowerPC 64 and 32 application binary interfaces (ABIs), so most PowerPC Linux binary files can run on K42 without modification, including the relational database DB2. K42 has some device drivers implemented specifically for it, but it gets most of its hardware support by directly linking in Linux device drivers to a special server. Another goal of the K42 design is to achieve a customizable and maintainable system. Being built with an object-oriented programming design, it allows applications to customize and thus optimize the OS services required, and then on the fly, hot swap kernel object implementations. This is particularly important for applications, such as databases and web servers, where the ability to control physical resources can improve performance. ==Open source==
