SDM is still available if you want it, and the others I'm aware of are on <http://arc.liv.ac.uk/SGE/tools.html>, apart from one funded with my taxes which I could never get hold of. (They could do with assessing and comparing, if someone would like to contribute. It would also be interesting to know how they compare with support in SLURM and OAR, for instance.) > Nevertheless there are scripts like > http://kimura.univ-montp2.fr/redmine/projects/cluster-tools/wiki/Greenginecode > making a little bit of looking ahead.

I doubt this job can be done well without support in SGE itself (e.g. scheduling as if "zombie" nodes were available). Note that power cycling may hurt reliability (see previous discussion here). Running with the Linux "ondemand" frequency governor significantly reduces consumption of idle nodes without significant problems we've seen. If necessary (latency effects?) you could flip between performance and ondemand in the usual SGE hooks. -- Community Grid Engine: http://arc.liv.ac.uk/SGE/ _______________________________________________ users mailing list [email protected] https://gridengine.org/mailman/listinfo/users
