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


User Bernd Dammann (<bd@imm.dtu.dk>) suggests to
have more flexibility in expressing load
thresholds and complex attribute values.

The objective is to avoid the need of manual
reconfiguration of SGE if the configuration of the
hardware changes. According the Bernd other RMS
systems like IBM's LL and Condor allow this.

From his mail:

"Would it be possible to enhance the functionality
of GE by allowing for the use of internal
parameters in definitions of other parameters,
i.e. the suspend/load thresholds 'load_avg =
num_proc' (this one is easy: np_load_avg = 1.0) or
'load_avg = num_proc - 2' (more difficult), or the
definition of slots in the host configuration:
'slots = num_proc -2' ? This is possible in other
queuing systems, e.g. IBM's LoadLeveler,
Condor, where one can combine internal (and user
defined) parameters into logical and arithmetical
expressions."
