sched.

This is closest to the spirit of the RTSJ but it does differ from the SCHED_OTHER policy used for regular Java threads.

Finally, the task_struct sits at the top, which fully describes the task and includes the sched_entity structure.

It exports a set of variables to the global namespace like $os, $pkg, $user, $proc, and $sched .

The primordial thread remains a regular Java thread and runs with a non-RT (SCHED_OTHER) policy.

Each scheduler module needs to implement a set of functions as suggested by struct sched_class.

sched_features: Contains information about various debugging-related features.

Furthermore, at any point, CFS promises to run sched_period ahead because the task last scheduled would run again within that window.

This function simply picks the left-most task from the red-black tree and returns the associated sched_entity.

SCHED_RR and SCHED_FIFO are intended to be used by applications requiring more deterministic and timely needs.

The SCHED_OTHER policy is used for traditional user tasks such as program-development tools, office applications, and Web browsers.

Instead, a new structure called sched_entity was created to track scheduling information (see Figure 2).

This behavior reverts to SCHED_OTHER when the regular Java thread releases the lock.

SCHED_FIFO does not time slice threads.

It is highly recommended that the sysctl value sched_yield_scale be set to 1 for Java performance.

The SCHED_OTHER policy is intended for applications such as compilers and word processors, not for tasks requiring more determinism.

The regular Java thread runs with SCHED_FIFO policy and so the thread does not time slice.

Both threads are assigned the same default priority in the SCHED_OTHER policy, so both threads are given the same time slice to execute.

The SCHED_FIFO policy is intended for RT and not for user tasks.

The parameters that you need to look at are sched_R and sched_D.

To prevent this situation, the JVM forces the primordial thread to have a non-RT priority -- that is, have a SCHED_OTHER policy.

Linux uses the sched_yield to do the same thing.

List time sched'ule' of "three same" , do the same thing at the same time and the same place.
