Eventually that's meant to be dealt with conveniently by
https://arc.liv.ac.uk/trac/SGE/ticket/1381.

Rather than mess with starters, my JSV does:

    if [ $(jsv_is_param pe_name) = true ]; then
	pe=$(jsv_get_param pe_name)
	pemin=$(jsv_get_param pe_min)
	pemax=$(jsv_get_param pe_max)
	late_pe=$pe
	case $pe in

            ...

	    smp)
		# Anyone using a PE range should set this to SLOTS
		# in the script.
		jsv_add_env OMP_NUM_THREADS $pemin
		;;
