SCHED_DEADLINE: what it does and doesn’t do, yet

2014/05/05 @ 13:15 - 14:15

Welcome to the seminar:

CHED_DEADLINE: what it does and doesn’t do, yet

Speaker: Juri Lelli,  Scuola Superiore Sant’Anna, Pisa

Date: 13:15 – 14:15 (incl questions), 5 May, 2014

Location: Seminar Room (M2112B) , Department of Automatic Control (Reglerteknik), M-Building, Ole Römers väg 1, Lund

Abstract: 

SCHED_DEADLINE is a new scheduling class for resource reservation-based
real-time CPU scheduling recently merged in the Linux kernel (version
3.14). It implements the real-time scheduling algorithm called Earliest
Deadline First (EDF), and thus allows for the possibility of analyzing
the system and enforcing, either statically (off-line) or dynamically
(on-line) determinism for the running tasks. SCHED_DEADLINE might be
particularly beneficial for time-sensitive workloads, such as
multimedia and/or control applications, where it may be important to be
guaranteed that some timing requirements will be met under any
circumstance. In this talk, starting from theoretical basis, a
low-level overview of the new scheduling class is provided. It is then
shown how it can be practically used by system administrators and
application developers.
