Re: [Algorithms] General purpose task parallel threading approach

[Jarkko L. <al...@gm...>]

Why is it a problem to execute the tasks in recursive way? Note that this
recursive way of executing tasks is used only when blocking within tasks,
not in the job queue dependency system.

 

 

Cheers, Jarkko

Without the ability to save/restore tasks your dependency system will have a
big bunch of limitations, because you can only execute tasks during a wait
in a recursive way ONLY.

You could also not have a wait for dependent tasks within a task, but rather
have job queue dependency system to take care of it by splitting the
function in two tasks. Or you could implement the wait by pulling tasks from
the job queue until the dependent tasks have been completed. There is no
context switches needed in either case though.
