nvthreads

NVthreads is a library that provides practical persistence for multi-threaded C/C++ applications by acting as a drop-in replacement for the pthreads library. It enables applications to recover their state after crashes, making them resilient to failures without requiring significant code changes.

Key Features

• Persistent Threading — Adds persistence to existing multi-threaded applications by inferring consistent states at synchronization points.
• Efficient Write Logging — Uses process memory to buffer uncommitted changes and logs writes to ensure data recoverability after crashes.
• Page-Level Mechanisms — Employs page-level tracking for performance, resulting in applications that can be more than 2× faster than fine-grained tracking systems.
• Crash Recovery — Allows iterative applications to resume execution after a failure, gaining speedups by avoiding complete restarts.
• Drop-In Compatibility — Designed as a direct replacement for pthreads, minimizing porting effort for existing applications.

Philosophy

NVthreads focuses on providing practical persistence through efficient mechanisms that balance performance with reliability, enabling multi-threaded applications to become crash-resilient with minimal overhead.
