The comparison results between two-level incremental checkpoint recovery scheme and two-level checkpoint recovery scheme for exponential distribution.

Abstract

<p>(a) The relationship between the total overheads of setting checkpoints and the number of failures; (b) The relationship between the total re-computing time and the number of failures; (c) The relationship between the total overheads of recovering from the failures and the number of failures; (d) The relationship between the system total overheads and the number of failures.</p
