TUDelft: KOALA• KOALA is a multicluster/grid scheduler• Main goals of KOALA:
Load sharing of jobs across the sites in a grid: Automatic resource selection
Co-allocation of jobs across the sites in a grid: In order to use more resources As dictated by the structure of applications
(e.g., simulation/visualization)• KOALA has been released on the DAS in
september 2005
