Hi,

 the kill command should be able to stop a job until you restart it.
Use kill -l to show you which signal names/numbers are available.

stop:    kill -STOP pid
restart: kill -CONT pid 

On our SGI machine we can use npri -h ndpri -p pid ....  (ndpri 128-255) to
change priorities. Such a job will only run if there is free CPU time on a 
machine. I do not know if other UNIX Version do have similar commands.
