In this talk we will present the new buddy-checkpointing feature of SIONlib, which is designed to support checkpointing of simulation data on node-local storage for application that uses a task-local I/O pattern. With this new feature, SIONlib is able to store data in a virtual shared file container on local storage of the compute nodes, whereas local data is automatically and transparently mirrored to local storage of a set of buddy nodes. The buddy-checkpointing feature of SIONlib has been developed within the EU-project DEEP-ER to support task-local I/O on hierarchical I/O infrastructures. Additionally, SIONlib can work together with the multi-level checkpoint library SCR to support buddy-checkpointing for SIONlib file container. |
