Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Parallel computation algorithms face performance degradation due to high overhead and limited bandwidth utilization caused by frequent sending of small data messages, which results in inefficient network usage.
Innovation Solution
Implementing a Message Aggregation Circuit (MAC) and Message Disaggregation Circuit (MDC) to aggregate and disaggregate messages sharing a common destination, reducing the number of messages and overhead by sending larger aggregated messages over the network, and processing them at the transport-layer level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If frequent small data messages are sent between processors, then communication frequency is improved, but network bandwidth utilization deteriorates and overhead increases
Solution Approach 1:
The patent implements a message aggregation circuit that combines multiple small data messages sharing a common destination into a single aggregated message. This merging process reduces the total number of messages transmitted over the network, thereby improving bandwidth utilization while maintaining the ability to communicate frequently with multiple processors. The aggregation circuit buffers incoming messages and consolidates them before transmission, resolving the contradiction between communication frequency and network efficiency.
2Speed
If multiple small messages are sent individually, then message delivery speed is improved, but protocol overhead increases
Solution Approach 1:
The message aggregation circuit merges multiple small messages into a single aggregated message, reducing the number of protocol headers and control structures that need to be processed. This significantly reduces protocol overhead while the circuit maintains message delivery speed by efficiently managing the aggregation and transmission process. The aggregation reduces redundant protocol processing for each individual message.
3Productivity
If messages are aggregated into larger batches, then network efficiency is improved, but message latency increases
Solution Approach 1:
The aggregation circuit dynamically adjusts its aggregation behavior based on real-time conditions such as message arrival rates, buffer status, and destination information. This dynamic operation allows the system to optimize between aggregation benefits and latency concerns, adjusting aggregation aggressiveness based on current network conditions and message priorities.
Solution Approach 2:
The patent segments messages by their destination, creating separate aggregation queues for different destination processors. This segmentation allows messages bound for the same destination to be aggregated together, while maintaining the ability to quickly transmit aggregated messages to their destinations. The segmentation approach reduces latency by organizing messages in a way that facilitates efficient batching without excessive waiting time.
4Productivity
If a message aggregation circuit is implemented, then bandwidth utilization is improved, but device complexity increases
Solution Approach 1:
The message aggregation circuit acts as an intermediary component between the message sources and the network transmission interface. This intermediary buffers, aggregates, and manages message flow, improving overall bandwidth utilization. While it does add a component to the system, the circuit integrates with existing message passing infrastructure and provides significant performance benefits that outweigh the added complexity.
Data Source
AI summary
An apparatus includes one or more ports for connecting to a communication network, processing circuitry and a message aggregation circuit (MAC). The processing circuitry is configured to communicate messages over the communication network via the one or more ports. The MAC is configured to receive messages, which originate in one or more source processes and are destined to one or more destination processes, to aggregate two or more of the messages that share a common destination into an aggregated message, and to send the aggregated message using the processing circuitry over the communication network.
