I am also in the need of spreading load across cores. Working with global
audio variables to communicate with fx instrs, there is no way known to me to
specify that an instrument is only a producer or a consumer of a specific
variable, and I can confirm that only one fx seems to serialize all "parallel"
producers. The Mixer* opcodes would solve the specification problem, but are
they used for the analysis to determine which instruments can be run in
parallel? My own results don't seem to show this. Is there a way to output the
dependency graph?

      One solution that it might be tried, for effects, is to use
      another Csound process for effects and connect it via Jack. You
      can run that process in a single thread.

the function to print semantic information is csp_orc_sa_print_list whic 
is commented out in Engine/new_orc_parser.c ad in OOPs/compile.c

I guess it could be made available under a -m flag, but if you have 
sources just  uncomment these lines
./Engine/new_orc_parser.c:137:      //csp_orc_sa_print_list(csound);
./OOps/compile_ops.c:73:    //csp_orc_sa_print_list(csound);
