Linux-compatible 64Bit-operating system K42 from IBM for PPC
K42 is a operating-system research project (available under LGPL) focused
in large part on scalability in the implementation of core OS services.
We will give a brief overview of the project, discuss some of the recent
performance results running 64-bit PPC Linux binaries and discuss the
major ways that our implementation of Linux services depart from the norm
(hopefully making sure to bring up all the truly offensive and contentious
ways).
K42 employs building-block technology to allow applications to customize
and thus optimize the OS services they require. This is particularly
important for applications, such as databases and web servers, where
given the ability to control physical resources, they can improve
performance. K42 is portable; it currently runs on PowerPC systems
(both native and using SimOS). K42's design allows implementors on a
particular architecture to choose what objects of the system should be
customized for that architecture, and as a result allows the implementors
to exploit any architecture specific features to improve performance.
