Each node represents a checkpoint and a directed edge m is drawn from Cp,i to Cq,j if (1) pžq, and a message from Iq,j-1 to Ip,i is not logged or (2) p=q and j=i+1. The checkpoints Cp,i and Cq,j are called head(m) and tail(m). Cp,i Ip,i Cp,i+1 Ip,i Cp,i+1 Pp Iq,j-1 Cq,j Pq (a) Cp,i Pp Iq,j-1 Cq,j Pq (b) Fig. 6. (a) Checkpoints and not required messages; (b) R2-graph Definition 1: R2-Graph d An R2-graph is a directed graph G=(C, → ), where C is a non-empty set of local d checkpoints on all processes, while → is a relation connecting checkpoints, such that d Cp,i → Cq,j means that there is an edge from Cp,i to Cq,j in G with “head” at Cp,i and “tail” at Cq,j.

Rollback recovery line Time Stripe group 0 Region 2 Stripe group 1 Region 1 Stripe group 2 Stripe group 3 Cp Fig. 4. Snapshot of an inconsistency state in staggered writes Region 1 in Fig. 4 shows the steps before checkpointing procedure and region 2 shows the steps after checkpointing each staggered group. Therefore, the recovery to the global snapshot lost all the messages between the two regions. Therefore, all messages crossing the snapshot should be logged to guarantee a global consistency.
