Sun Grid Engine (SGE) installation

What is it?

• the logistics master of the computational cluster
• harnesses idle compute resources and matches them to individual job requirements, delivering network-wide computational power
• helps solve the problem of how to apply maximum resources to a single compute-intensive problem

Installation of SGE

• download SGE source from http://wwws.sun.com/software/gridware/linux/
• create user account for queue system administrator (user "sgeadmin")
• create installation directory (/usr/local/sge)
• run "install_qmaster" and "install_execd" on unisys08 (Mike's desktop)... this machine will handle all the job control as well as participate in the computational cluster
• export and mount to node01, node05, and node08 via NFS
• run "install_execd" on the nodes... all three will work together with unisys08 in the computational cluster

Configuration of SGE

• set all four queues for Batch (Serial) and Parallel jobs only using "qmon"
• configure Parallel Environment (MPICH); create queue list

Why?

• organizes the task into subtasks and assigns subtasks to each CPU in the cluster
• allows a computationally difficult task to be completed much faster simply due to availability of extra system resources
