[PD] disable cores on linux to use as dedicated dsp

[Simon Iten]

hi list,

i recorded 3 times in a studio last year that uses a daw/pc 
interconnection by pyramix, basically it is a hacked windows system, 
where one or two cores of a multicore cpu are completely hidden from the 
system. these cores are then acessed directly by the daw and used as a 
very powerful dsp. the system is incredible! lowest latencies, high 
trackcount, and the breakout to the adc/dac is a simple network cable.

see here for additional info:

i since wondered if this would be a way to go for puredata? at least on 
linux it seems very easy to deactivate a core (but i don't know if it 
than can be used directly by a process) : echo 0 > 
/sys/devices/system/cpu/cpu1/online for core2 for example.


is this a completely stupid idea? note that i have no idea how hard it 
would be to implement something like this


thanks for any insight
