Fundamental Concept about computing Grid Operating System & GOS A Interoperate interface of GOS using JSAGA Outlines

A GOS Interoperate Interface's Design & Implementation What is Grid Computing?

Job is just a command – It can be a shell command hostname > hostname.out – It can also use other software What is a job?

Job execution on one machine – Executes like any other program Job execution on several machine – Paralleling computing MPI – LRMS PBS LSF Condor Slurm How a job executes?

Aggregated the resources Use the resources more efficiently Easier for use Why use Grid?
