Hi all, Some two year I wrote a library to change thread priorities in Windows, including another library that allows real time processing. With this you can play midi files real time and without interruption from the OS. (Manipulating thread priorities is really easy in Windows, real time uninterrupted processing a little more complicated). Actually, I thought this problem was already resolved (haskore-realtime), but if there is interest I can see if I can dust them off, although I'm sure there will be still lots of things to improve. Right now I'm working in linux only, so it may take a few days to get a suitable xp version. (Actually, I would be really interested in a linux port, but have little time right now. Perhaps this library can help: http://sourceforge.net/projects/high-res-timers ?) Kind regards, Maarten Christopher Lane Hinson wrote:
Is there any interest or movement in developing thread priority or any other realtime support in Haskell?
Right now, if I have tasks that need to be responsive in real time, even if the realtime needs are very soft, it seems that the only option is to try to ensure that at least one hardware thread is kept clear of any other activity.
To be very useful to me, thread priority would not need to come with very strict guarantees, but there would need to be a way to make sure that `par` sparks and DPH inherit the priority of the sparking thread.
In part I ask because I'm working on a small library to support a degree of cooperative task prioritization.
