Within the DEEP-ER the network attached memory (NAM) device complements the memory hierarchy. It is connected to the DEEP-ER network and serves as a shared global storage resource that can be addressed from both the Cluster and the Booster Nodes. Application developers can make use of the NAM for XOR-checkpointing in 2 different ways:
- With SIONlib
- With SCR+SIONlib
For the first approach the user only has to adapt the checkpoint mode and the path for the checkpoints within the file open function of SIONlib. For the second approach SCR can be used the same way it is used for buddy-checkpointing, just a few parameters need to be adapted.
