rtrace error message "only single process supported"

Hello all,
I tried to use rtrace -n option like below, but returned error message was
"only single process supported". Why can I use parallel calculation?

rtrace -I -h -dp 2048 -ar 32 -ms 0.063 -ds .2 -dt .05 -dc .75 -dr 3 -n 2
-st .01 -ab 5 -aa .1 -ad 2048 -as 256 -av 0.01 0.01 0.01 -lr 12 -lw .0005
-af ***.amb ***.oct < ***.pts > ***.dat

My computer specs are
OS:Windows XP professional SP3
CPU:core 2 duo T9300 2.5Ghz ( I command rtrace -n 2 )
Memory : 3GB
Radiance windows binaries are downloaded from here.

Thank you for all your advice.

No one has figured out how to coordinate processes on Windows yet, so the -n option is not supported there.

Sorry.
