Geometric Checkpoint. AB - Grid Computing has become major player in super-computing community. But due to the diversity and disruptive nature of its resources, failure of jobs is not an exception. However, many researchers have come up with models that enhance jobs survivability. Popular among this model is checkpoint model which have the ability of saving already computed jobs on a stable secured storage. This model avoids re-computing of already computed jobs from the scratch in case of resources failure. But the time a job takes in checkpoinitng also becomes another task which adds overheads to computing resources thereby reducing the resources performance. In order not to add too many overheads to computing resources, the number of checkpoints must be minimized. This study proposed checkpoint interval models which is implemented based on fault index history of computing resources. Failed jobs are re-allocated from their last saved checkpoint using an exception handler. The study observed that arithmetic checkpoint model is better used when fault index of computing resources is high while geometric checkpoint model is better when fault index of resources is low.
