Byte.com: Process Scheduling In Linux, A Time For Everything

“Last month, we started a new series of Linux kernel internals.

why in many ways Linux is better at creating and maintaining
processes than many commercials Unixes.”

This series on Linux internals is by the way the fruit of a
tight collaboration with some of the most experienced kernel
hackers in the Linux project.
Without the contribution of

employee), Ingo Molnar (scheduler contributor) and many others,
this series wouldn’t be possible. Many thanks to all of them, but
especially to Andrea Arcangeli who has shown a lot of patience in
