i am wondering what the current options for the use of multicore are. i 
don't know if this is the same as parallel csound.

i am building csound on linux with scons. i have a quad core processor. 
i have built with the scons option -j 4 -- is this actually correct?

i had a look at the csound flags 
(http://www.csounds.com/manual/html/CommandFlags.html) but i couldn't 
find any option which is related to multithreading.

is it in any way possible to tell csound to use 1, 2, or more threads in 
parallel?

thanks -

Do you mean buildingf or running?

scons -j 4 will use 4 threads to BUILD csound.  To run wil 4 threads use
csound -j 4 ....

May or may not give better performance depending on ksmps and weight of
instruments etc etc

I am about to write a longer messafe abour csound on multicore to the
developer list following yesterday

ah, so -j is the csound flag i couldn't find - thanks.
