------------------------


On HP multi-CPU machines the load values retrieved
by SGE are already dived by the number of
processors (most probably already done by the
system calles, since the "uptime" command has a
similar behavior).

This happens on HP-UX 10 and HP-UX 11.

Therefore the load values (load_* and np_load*)
are too small compared to all other supported SGE
architectures).

Workaround: use load scaling

fixing it for 5.3.1 and maintrunc.

Load values were divided by the number of processors in the code
retrieving them for the hp11 architecture.

Fixed for 5.3 branch and maintrunc.

Should still be verified by a user having access to such a machine.

A user (Laurent Aymeric) reported correct behaviour on a 6 cpu machine.
Thanks Laurent!
