VeloC is a multi-level checkpoint/restart runtime that delivers high performance and scalability for complex heterogeneous storage hierarchies without sacrificing ease of use and flexibility.

It is primarily used as a fault-tolerance tool for tightly coupled HPC applications running on supercomputing infrastructure but is essential in many other use cases: suspend-resume, migration, debugging.

VeloC is a collaboration between Argonne National Laboratory and Lawrence Livermore National Laboratory as part of the Exascale Computing Project.

The documentation of VeloC is available here: http:https://veloc.rtfd.io

It includes a quick start guide as well that covers the basics needed to use VeloC on your system.
