[gridengine users] load sensor for weather forecast?

[Tiago Baptista]

A suggestion I would make is to use a sensor to mesure the cluster room temperature. Most UPS (at least from APC) have these kind of sensors, and its fairly easy to access its reading.

I am currently writing a small utility to shut down and bring up nodes, based on cluster load. But I guess the same type of procedure could be implemented for temperature rather than load.
