Simulation based study of communication induced checkpointing Protocols ensuring the RDT property

The execution of a distributed computation, extended with a checkpointing protocol, produces a Checkpoint and Communication Pattern (CCP), which consists of the set of local checkpoints plus a dependency relation on those checkpoints. Communication induced checkpointing protocols are made to satisfy an interesting properties such as Rollback-Dependency Trackability (RDT) which ensures that all local checkpoints dependencies are on-the-fly trackable. In this paper we are interested in CIC protocols ensuring RDT property and the simulation with ChkSim that allow us to evaluate their performances. ChkSim gives us a global vision of different properties of these protocols. The simulation is carried out in point to point environment under different scenarios. The variation of simulation parameters allows us to study the influence of processes number, interval length between two basic checkpoints, asymmetric and the number of fast processes.
