Steps to reproduce:
6.2u2_1 Cluster with two nodes, mpi CT installed. Normal PE and Q set up.
In my example I have two nodes named rabbit and aubing:
$qsub -pe orte 4 -q mpi.q pe_hostfile.sh
Your job 88 ("pe_hostfile.sh") has been submitted
$ cat pe_hostfile.sh
/opt/SUNWhpc/bin/mpirun -np 4 /home/tv9055/hpc/sge_mpi_scripts/test.sh
$ cat test.sh
And the result is:
$ cat pe_hostfile.sh.o88
Warning: no access to tty; thus no job control in this shell...

This path is wrong. It does not exist and hence mpi programs which use
The PE_HOSTFILE may not be provided to pe slave tasks, only the master task needs this information.
The customer used this PE_HOSTFILE information on slave task side and ran into problems, due to this changes. This is a not documented
feature. The customer changed his scripts and jobs and everthing is working again.
But the availablity of PE_HOSTFILE for slave tasks should be removed.
