Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing computational capabilities of computing systems outpace data transfer rates, leading to a bottleneck in data throughput and limiting computation performance, particularly in systems with conventional von Neumann architectures and distributed systems, where data movement between processing cores and memory becomes a dominant performance limiter.
Innovation Solution
Implementing a memory system with a shared response component and tracking logic to coalesce memory operation messages into combined messages, reducing data transfer throughputs without requiring software awareness of data locality, by identifying coalesceable responses and merging them into a single communication path, thereby alleviating throughput restrictions.

Engineering Contradiction Analysis
1Productivity
If parallel memory operation messages are processed individually through conventional von Neumann architectures, then each message can be handled with simple routing logic, but data transfer throughput becomes a dominant performance bottleneck
Solution Approach 1:
The patent merges multiple parallel memory operation messages into a single aggregated message by identifying common destination addresses and combining their data payloads. This consolidation reduces the number of individual transfer operations required, thereby improving overall data transfer throughput and alleviating the performance bottleneck without requiring complex per-message routing logic
Solution Approach 2:
The system performs preliminary analysis of incoming memory operation messages to identify coalesceable operations before they are transferred. By pre-grouping messages with common destinations and preparing aggregated transfer operations in advance, the system optimizes data transfer throughput before the actual transfer occurs, preventing the bottleneck from forming
2Productivity
If data is transferred individually from memory to processing cores, then data movement can be simple and direct, but the volume of data transfer becomes excessive and limits computation performance
Solution Approach 1:
The patent combines multiple data transfers into a single aggregated transfer operation by grouping messages destined for the same or overlapping memory addresses. This merging reduces the total volume of data transferred across the memory interface, as redundant or overlapping transfers are consolidated into single operations carrying combined payloads
Solution Approach 2:
The system changes the parameters of data transfer operations by transforming multiple small individual transfers into fewer large aggregated transfers. This parameter change affects both the size and frequency of transfer operations, reducing overall data transfer volume while maintaining the necessary data delivery to processing cores
3Speed
If conventional memory systems process each memory operation separately, then routing and addressing logic remains simple, but throughput restrictions dominate system performance
Solution Approach 1:
The patent introduces an intermediary component between the memory interface and processing cores that performs message coalescing. This intermediary analyzes incoming messages, identifies coalesceable operations, and aggregates them before forwarding to destinations. The intermediary handles the complexity of throughput optimization while keeping the core memory and processing components relatively simple

AI summary
In accordance with described techniques for reduction of parallel memory operation messages, a computing system or computing device includes a memory system that receives memory operation messages. A shared response component in the memory system receives responses to the memory operation messages, and identifies a set of the responses that are coalesceable. The shared response component then coalesces the set of the responses into a combined message for communication completion through a communication path in the memory system.
