How to showing the equivalent Tandem (NSK) process id of the OSS ?process?

The -l option of the ps command shows the CPU,PIN in the ADDR (address) column:

jojo@\rat:~ $ ps -l
F S UID PID PPID C PRI NI ADDR SZ WCHAN TTY TIME
CMD
000 0002 5300 318308420 1 - 175 - 0,347 - - #ptcaamr
00:00 /bin/-sh
000 2002 5300 234422338 318308420 - 175 - 0,491 - - #ptcaamr
00:00 ps


You could also use the '-o addr' option:
jojo@\rat:~ $ ps -o addr,command
ADDR COMMAND
0,347 /bin/-sh
0,410 ps -o addr,command
