Parallel job management in grid with non-dedicated resources

The problem of parallel job management was successfully solved many times for the nearest analogs of the grid — cluster and MPP systems, however under grid conditions it becomes more complicated and new approaches are required for its solution. The main difficulty is the necessity of accumulation and then guaranteed synchronous allocation of resources in several clusters (co-allocation of resources). In the paper a solution for this problem is proposed by means of the lookahead scheduling method designed for the practically important form of the grid with non-dedicated resources that are not granted to the grid completely but are shared with their owners.
