AFAIK this is deprecated on the configuration level, as it moved to the queue
definition `qconf -mq all.q`.

A plain `qsh` is working for you? This is an old startup method due to the
insecure X11 startup it shouldn't be used any longer IMO.

It's 7:45 to 3:32 - both in minutes:seconds, or?
All machines are the same regarding speed and core count? BTW: running
interactively in SGE might not set environment variables in case you use `qrsh`
without a command or `qlogin` and some default hostfile will be used instead
(unless you provide one). Below with the supplied command it should be fine.
