ChronOS Real-time Linux

ChronOS is a real-time Linux patch created by the Systems Software Research Group at Virginia Tech. It builds upon the CONFIG_PREEMPT_RT patch and is designed to provide a Linux kernel testbed for real-time scheduling and resource management research on multicore platforms. It also supports distributed real-time scheduling and resource management.

The current version of ChronOS is ChronOS 3.0 which is based on Linux kernel 3.0.24 and the CONFIG_PREEMPT_RT patch.
