Computational clusters

Linux for Engineering and IT applications

Sun Grid Engine (SGE) On multi-user and multi-tasking cluster the resources should be managed through a queue scheduling system, such as SGE, LSF, PBS, Condor. Sun Grid Engine daemons Master host: controls queues jobs schedules on the whole cluster Computational hosts run jobs
