Hi,
First off, I'd like to thank the academy for an excellent BoF at the recent
LinuxWorld Conference and Expo. Well done, lads.
Second, I am running RTL very successfully on a 486, 66MHz, 32Mb but want to
upgrade the hardware. The project involves reading some (APDs) photon counters
at rates up to tens of kHz (if we can) and manipulating the incoming signals
(which might be equally spaced in time and mighht not) to provide position
demands for a (tip-tilt) mirror (at several kHz).
When I spec'ed the machine required I came up with a Pentium, 64Mb, 200MHz.
Now, however, I am changing my thinking as I want to run LabView as well.
One choice I have (money isn't a problem for the cost of purchase I expect),
is to buy a dual Pentium II and run the RT code on 1 processor and LabView
(and other non RT code) on the other. Since LabView is a bit of a memory hog
we would go with a minimum 128Mb - but as I say price is not an issue. I
would also envisage using the Zentropix R2D2 and RT Designer tools during this
project.
The questions are:
1. Is patching the kernel for SMP as easy as vanilla Linux?
2. Is anyone running a similar configuration and are there any gotchas?
3. How well does the SMP RT-Linux (that's a bit of a mouthful) perform?
4. Are there any (unusual) software issues with going to SMP RT-Linux in
this environment?
Thanks in advance for any advice you might be able to give.
