Subject[Csnd] csound 5.09 with jackdmp
trying to use csound 5.09 with jackdmp on windows xp on my quad core pc,
i expperience some strange processor behavior. csound seems to work fine, but when i start it one processor gets 100% used and the csound instance seems to run on the second processor. so running csound i have 25% overall cpu usage even if csound isn´t doing anything, and up to 50% when csound is computing heavy.
since i installed jackdmp the same problemm occurs even when using asio instead of jakport...
starting csound with python doesnt help, but running csound in max/msp does. there is no strange cpu stress when csound is loaded with csound~.

maby someone has an idea what causes this problemm?
is anyone using jackdmp with csound on win xp with sucess?

best regards,
friedrich

thank you andreas,
i guess its not a denormal problem because all csd files i tried stress the cpu, even those wich dont do any audio procssing...

but jack1.9 or jackdmp (http://www.grame.fr/~letz/jackdmp.html) works fine for me on xp.
i tried it for routing signals between maxmsp, csound and an older version of wavelab.
the only serious problemm i experienced is the csound one i described.

the dev list is fine for me, i will register to it now.

Hi Friedrich,

This is an interesting report, what csd are you using to test? Are you
sure it's not a denormal problem? (Not sure if this is still an issue
with newer cpus).

I didn't know you could use jack on windows! That's very interesting
news. How usable is it right now?

Would you like to take this discussion to the dev list?

Cheers,
Andrés
