Welcome to Cedana! This repository is the home of the cedana daemon and the low-level orchestration of our save/migrate/resume (SMR) functionality, and is the entry-point into the larger cedana ecosystem.
We build on top of and leverage CRIU to provide userspace checkpoint/restore of processes and the many different abstraction levels that lie above. We also provide the ability to checkpoint/restore rootfs in both containerd and CRIO interfaces for full container checkpoint/restores.
For a list of supported runtimes, see our container support matrix.
We can monitor, migrate and automate checkpoints across a real-time network and compute configuration enabling ephemeral and hardware agnostic compute. See our website for more information about our managed product.
Some problems Cedana can help solve include:
- Cold-starts for containers & processes
- Keeping a process or container running independent of hardware/network failure
- Managing multiprocess/multinode systems (independent of Kubernetes/SLURM or any orchestration)
- GPU checkpoint/restore
- And more!
Cedana needs libgpgme, libbtrfs and libseccomp on the machine to build against. On a debian based system, you can install them with:
apt install libgpgme-dev libseccomp-dev libbtrfs-devon centOS/RHEL:
yum install gpgme-devel libseccomp-devel btrfs-progs-devel To build:
go build.
