Transactional Memory Lock Translation for Concurrency Bottlenecks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current memory management in multi-threaded applications faces challenges with synchronization overhead, lock contention, and the complexity of implementing transactional programming, which hinders concurrency and increases development costs.
Innovation Solution
A method and system that dynamically identify memory contentions by analyzing processor utilization and replacing regular lock/unlock instructions with transactional/speculative lock acquire and release instructions, allowing for speculative execution without requiring programmer intervention or access to source code, leveraging TSX or similar processor features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fine-grain locks are used to reduce synchronization overhead, then concurrency is improved, but device complexity and difficulty of implementation increase
Solution Approach 1:
The system automatically performs binary translation to insert transactional synchronization code without requiring programmer intervention. The translation module autonomously analyzes the binary code, identifies synchronization points, and inserts appropriate transactional instructions, making the system self-configuring and eliminating the need for manual fine-grain lock implementation.
Solution Approach 2:
A binary translation module acts as an intermediary between the executable binary and the processor. This intermediary automatically transforms regular synchronization instructions into transactional synchronization instructions, bridging the gap between legacy code and modern transactional processing capabilities without requiring source code access or programmer modification.
2Object-generated harmful factors
If transactional programming is implemented to reduce synchronization overhead, then memory contention is reduced, but ease of operation decreases due to required programmer training and code modification
Solution Approach 1:
The system automatically performs binary translation to insert transactional synchronization code without requiring programmer intervention. The translation module autonomously analyzes the binary code, identifies synchronization points, and inserts appropriate transactional instructions, making the system self-configuring and eliminating the need for manual fine-grain lock implementation.
Solution Approach 2:
The binary translation is performed in advance during system initialization or code loading, converting regular synchronization instructions into transactional instructions before execution. This preliminary transformation eliminates the need for programmers to manually modify code or receive special training, as the translation happens automatically prior to runtime.
3Productivity
If speculative execution is used to improve processor throughput, then productivity increases, but use of energy increases due to additional transactional execution overhead
Solution Approach 1:
The system extracts and eliminates redundant synchronization operations by replacing them with transactional execution. By removing unnecessary lock acquire/release pairs that do not provide actual synchronization value, the system reduces both execution overhead and energy consumption while maintaining correctness through speculative execution.
Solution Approach 2:
The system applies transactional execution selectively only to critical sections that benefit from it, rather than universally to all code. The binary translation module identifies and marks specific synchronization regions for transactional execution, applying the energy-intensive speculative execution technique only where necessary to achieve throughput improvements.

A disclosed example apparatus includes memory; and processor circuitry to: identify a lock-protected section of instructions in the memory; replace lock/unlock instructions with transactional lock acquire and transactional lock release instructions to form a transactional process; and execute the transactional process in a speculative execution.
