Accelerating Burst Parallelism of SigmaOS processes with CRIU
… processes using Checkpoint/Restore in Userspace (CRIU). CRIU is a linux toolset which can start new server instances by restoring them from a saved checkpointed state, avoiding the full cost of reinitialization and setup. This thesis introduces σCRIU, which adapts CRIU for burst-parallel spawning …

CRIU-RTX: Remote Thread eXecution using Checkpoint/Restore in Userspace
… application modifications. We introduce CRIU-RTX, a userspace framework to scale-out multi-threaded applications across multiple nodes. Integrated with HetMigrate, a prior work on migrating processes across heterogeneous-ISA systems, CRIU-RTX can suspend a subset of threads in a process …

Live Library Upgrades via CRIU: A Novel Approach to Patch Security Vulnerabilities in Running Processes
… it. Using Checkpoint/Restore in Userspace (CRIU), we freeze a process, modify its state, and resume execution with the patched code seamlessly integrated. The approach combines metadata edits, address translation, and memory dump rewriting. By patching file backed mappings and leveraging ELF …

Stretch: Scalable Multi-Threaded Execution for Distributed Machines
… clusters. The system integrates and extends CRIU checkpoint/restore to migrate arbitrary subsets of threads to remote nodes, and leverages userfaultfd to intercept missing and write-protection faults in user space. These faults drive a centralized MSI-style write-invalidation coherence …

rave: A Framework for Code and Memory Randomization of Linux Containers
… static binary analysis and instrumentation, and CRIU-rave, an extended version of the battle-tested process migration tool available for Linux. In our prototype of this framework, we have shown that these tools can be used to rewrite live applications, like NGINX, with enough randomization to …

HetMigrate: Secure and Efficient Cross-architecture Process Live Migration
… systems. HetMigrate integrates with CRIU, a Linux mechanism for process migration, and runs on stock Linux operating systems which improves its deployability. Furthermore, HetMigrate transforms the process's state externally without instrumenting state transformation code into the …
