I believe it is as I can't enter it at the qsub command line either. I fix it up in the jsv. I believe you can qalter the PE to include square brackets though which works. The man page says the -pe option accepts a parallel_environment and the commentary implies that this is a pe_name. However while qsub enforces this (excluding square brackets) the scheduler interprets it as a wc_pe_name which permits them. The ? and * characters are valid in either pe_name and wc_pe_name but with different meanings (literal in the first, metacharacters in the second). However that isn't the problem. The wildcard PE works for every other job. The oddity is that this job doesn't get a reservation when other jobs with lower priority and less restrictive resource requirements (and similar wildcard PEs) do and that qalter claims these PEs have "only" 2 billion slots which is apparently not enough for a 128 slot job. While I suppose it is legal for use of an undocumented feature to cause demons to fly out of my nose I doubt that is what is happening here.
