Hi,

I want to know which scheduling method EMC2 is using to assign the task to the processor. Is it a FIFO-scheduling or something else?

I am actually writing a report about EMC2 and would appreciate any information about the scheduler.

Thanks,

Toby

I found the following:

RTAI task scheduling uses a priority based preemptive scheduling algorithm as default

Source: www.cs.ru.nl/lab/rtai/experiments/8.Prio...ng/Experiment-8.html

just to complete this thread. However, this source doesn't mean that EMC is really using it. But i guess it is using RTAI and maybe the developer just let this setting by default.
