CRUM: Checkpoint-Restart Support for CUDA's Unified Memory
[article]
2018
arXiv
pre-print
Preserved Fulltext
A new scalable checkpointing mechanism, CRUM (Checkpoint-Restart for Unified Memory), is demonstrated for hybrid CUDA/MPI computations across multiple computer nodes. ...
CRUM supports a fast, forked checkpointing, which mostly overlaps the CUDA computation with storage of the checkpoint image in stable storage. ...
This work was partially supported by NSF Grants ACI-1440788 and OAC-1740218, and by Grant 2014-345 from a "Chaire d'attractivité" de l'IDEX, Université Fédérale Toulouse Midi-Pyrénées. ...

CRAC (Checkpoint-Restart Architecture for CUDA) is new checkpoint-restart solution for fault tolerance that supports the full range of CUDA applications. ...
CRAC combines: low runtime overhead (approximately 1% or less); fast checkpoint-restart; support for scalable CUDA streams (for efficient usage of all of the thousands of GPU cores); and support for the ...
We also thank Rohan Garg for conversations describing his earlier design of CRUM for CUDA. ...
