Directories: oskit/threads/cpuinherit
Documentation: doc/pthread.tex
Original Code Source:
Flux Research Group, University of Utah
Description:
This directory contains an implementation of CPU Inheritance
Scheduling; the idea was presented in the Utah OSDI'96 paper
[FordSusarla]. To compile the threads directory with CPUI
instead of the standard POSIX scheduler, define CPU_INHERIT in
the threads GNUmakerules file.
This version of the code is somewhat buggy. At times
scheduling operations will be missed and the program will hang
because a thread wakeup did not happen. The next version will
be much better.
There are four schedulers. First is a standard POSIX
scheduler, which is used as the root scheduler, but can also
be instantiated as a FIFO/RR scheduler anywhere else in a
hierarchy. Also included are very simple implementations of
RateMono, Lotto, and Stride schedulers.
