Decoupling Atomicity from Operation Size - A simplified explanation of the abstract
This abstract first appeared for US patent application 18587289 titled 'Decoupling Atomicity from Operation Size
The abstract describes a processor that implements a different atomicity size for memory consistency order than the operation size. This means that the processor may have a smaller atomicity size compared to the operation size. For example, the atomicity size for multiple register loads may be the register size. Similarly, the vector element size could be the atomicity size for vector load instructions, and multiple contiguous vector elements, but fewer than all the vector elements in a vector register, may be the atomicity size for vector load instructions.
- Processor implements different atomicity size for memory consistency order than operation size
- Smaller atomicity size compared to operation size
- Examples include register size for multiple register loads and vector element size for vector load instructions
- Multiple contiguous vector elements may be atomicity size for vector load instructions
Potential Applications: - High-performance computing - Data processing applications - Parallel computing systems
Problems Solved: - Improved memory consistency order - Enhanced efficiency in data processing - Optimized performance in parallel computing
Benefits: - Faster data processing - Enhanced memory management - Improved overall system performance
Commercial Applications: Title: "Enhancing Memory Consistency Order in High-Performance Computing Systems" This technology could be utilized in: - Supercomputers - Data centers - Cloud computing infrastructure
Questions about the technology: 1. How does the implementation of different atomicity sizes improve memory consistency order?
- By allowing for smaller atomicity sizes, the processor can optimize memory operations for better performance.
2. What are the potential drawbacks of having a smaller atomicity size compared to the operation size?
- Smaller atomicity sizes may lead to increased complexity in memory management and potential issues with data integrity.
Original Abstract Submitted
In an embodiment, a processor implements a different atomicity size (for memory consistency order) than the operation size. More particularly, the processor may implement a smaller atomicity size than the operation size. For example, for multiple register loads, the atomicity size may be the register size. In another example, the vector element size may be the atomicity size for vector load instructions. In yet another example, multiple contiguous vector elements, but fewer than all the vector elements in a vector register, may be the atomicity size for vector load instructions.
