Some further research proved me wrong: the above config line does not instantiate the intelmpi_* PEs from a template PE (intelmpi). Rather, it assigns different PEs to different instances of the queue: something.q@@ib1 has intelmpi_ib1, something.q@@ib2 has intelmpi_ib2, and every other instance has intelmpi.
So, I have defined intelmpi_ib1 and intelmpi_ib2 to be identical copies of intelmpi (except for the names, of course). After creating these, qconf added a queue with the above pe_list all right.
