Transform live program state (i.e., CRIU images) between different architectures for native binaries.
🚀 Quickstart Guide
You can try Dapper on an x86 server running Ubuntu 22.04 or later by following the two steps below:
- Step 1: Setup VMs using Docker (~20 minutes)
- Step 2: Live Migrate a Program Cross Architectures (~20 minutes)
Dapper was built on top of CRIU to dump a running process and then transform the CRIU images to support restoration on servers of a different architecture. Currently, Dapper supports process migration on x86-64 and aarch64 CPUs. Dapper uses LLVM's stack maps to generate stack and register metadata and implements a stack and register transformation logic leveraging the generated metadata. It does this on CRIU dumped images and hence does not involve injecting transformation runtime within the binary image improving security.
This repository provides the CRIU wrapper and the compiler toolchain can be found on this branch of the popcorn compiler repository.
