Something little OT, but what exactly is the difference between<br>
Windows/Mac, where one doesn't need an rt kernel to run realtime<br>

Hello Moshe,<br>
<br>
On Linux you don't need a real-time kernel to run real-time processes<br>
either.<br>
<br>
</blockquote>
to clarify a little more:<br>
<br>
1) on linux, **access** to realtime scheduling is not necessarily<br>
granted to normal users, unlike the situation on windows and OS X. on<br>
any sane linux system, this is easy to alter. on any sane linux system<br>
that targets music/pro-audio/media production, its already set up that<br>
way and so there is no difference between these systems and windows or<br>
OS X in this regard.<br>
<br>
2) the PREEMPT_RT kernel is substantially "more realtime" than any<br>
version of windows or OS X that you could lay your hands on. its more<br>
like an actual realtime OS than the kind of general purpose OS that<br>
regular Linux, Windows and OS X represent, though without actually<br>
being suitable (quite) for "hard RT" tasks.<br>
<br>
</blockquote></div>
To add, even if it's not IMHO something good, (clearly it's a shameful job) :<br>
Linux machines are the standard for "high frequency trading"<br>
Almost just because they can really go RT<div><div></div><div class="h5"><br>
