Induced Multi-threading Framework for Code Marking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Developers face challenges in transforming sequential software code into concurrently executable code due to platform constraints, such as those imposed by J2EE, which limits thread usage and makes it burdensome and counter-intuitive to identify and modify code for concurrent execution.
Innovation Solution
The Induced Multi-threading (IMT) framework uses a marking API to identify and transform blocks of code for concurrent execution, allowing developers to specify priority, dependency, and duration information, enabling multi-threaded execution without altering the code's semantic behavior, and generating concurrent code that can execute across different platforms and architectures.

Engineering Contradiction Analysis
1Productivity
If code is transformed to execute concurrently using traditional methods, then execution efficiency is improved, but code complexity and difficulty of maintenance increase
Solution Approach 1:
The code is divided into independent blocks that can be executed concurrently. Each block is marked with a marker indicating it can run in a separate thread, allowing the system to segment the sequential code into parallel-executable units without requiring developers to manually create complex thread management structures.
Solution Approach 2:
A compiler intermediary is introduced that automatically transforms marked sequential code blocks into concurrent code during compilation. This intermediary handles the complexity of thread creation, synchronization, and coordination transparently, shielding developers from concurrency complexity while enabling parallel execution.
2Productivity
If traditional code rewriting methods are used to enable concurrent execution, then performance is improved, but ease of operation deteriorates
Solution Approach 1:
Developers perform preliminary marking of code blocks during the sequential development phase, indicating which blocks are independent and suitable for concurrent execution. The actual transformation into concurrent code happens automatically during compilation, eliminating the need for developers to manually rewrite complex concurrent code structures.
Solution Approach 2:
The compilation system automatically performs the complex task of transforming marked sequential code into concurrent code without requiring manual intervention. The system services itself by detecting marked blocks and generating appropriate concurrent code structures, thread management, and synchronization mechanisms automatically.
3Productivity
If platform-specific thread usage is implemented, then concurrent execution is achieved, but adaptability to different platforms decreases
Solution Approach 1:
The marking mechanism is designed to be platform-agnostic, using language-level annotations that can be applied uniformly across different platforms. The compilation process translates these universal markers into platform-specific concurrent code, allowing the same marked source code to be compiled for different platforms (Java, C++, C#) with appropriate concurrency support.
Solution Approach 2:
The system changes the parameter of code representation from platform-specific thread implementations to platform-independent marked blocks. During compilation, the markers are transformed into appropriate platform-specific concurrency constructs, allowing the same source code to adapt to different platform requirements automatically.

AI summary
A method to instrument software code may comprise marking one or more blocks of code in an application program to provide a marked code. The marking may comprise inserting a marker at each of the one or more blocks according to a marking application programming interface (API). The one or more of the blocks of code marked according to the marking API may be transformed so that one or more functions are performed for the marked blocks. The one or more functions may not be part of the application program. The method may include executing the application program and performing the one or more functions for the marked blocks.
