Re: a joint letter on low latency and Linux

[Cort Dougan]

Can you characterize what you mean by extensive?  You can do FP in
RTLinux.  If you're going to be doing heavy computation you're not going to
want to hold the cpu in RTLinux and should ship the data off to a
user-level task to do the number crunching.  Do you need to respond to an
event, in realtime, and provide a response (that requires FP) within a
given interval?

It does do SMP.  In fact, we've had good numbers from kicking Linux off a
processor and doing just RTLinux on it.  Can you characterize what exactly
you need RTLinux to do with regard to SMP for you?  If so, we can tell you
if it can or can't do it :)
