Fence Enforcement Techniques based on Stall Characteristics - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240095035 titled 'Fence Enforcement Techniques based on Stall Characteristics
Simplified Explanation
The patent application describes techniques for managing channel stalls or deactivations based on the latency of prior operations in a processor with multiple channel and execution pipelines.
- The processor includes multiple channel pipelines and execution pipelines shared by the channels.
- Scheduler circuitry assigns threads to channels and operations to execution pipelines based on decode information.
- Dependency circuitry determines whether to stall an operation or deactivate a thread based on status information from prior operations.
Potential Applications
This technology could be applied in high-performance computing systems, data centers, and other environments where efficient task scheduling and resource management are crucial.
Problems Solved
This innovation addresses the challenge of optimizing processor performance by dynamically managing channel stalls and thread deactivations based on the latency of prior operations, reducing bottlenecks and improving overall efficiency.
Benefits
The benefits of this technology include improved processor throughput, reduced latency, better resource utilization, and enhanced overall system performance in complex computing environments.
Potential Commercial Applications
Potential commercial applications of this technology include server systems, cloud computing infrastructure, scientific computing clusters, and any other high-performance computing environment where efficient task scheduling and resource allocation are essential for optimal performance.
Possible Prior Art
One possible prior art in this field could be techniques for thread scheduling and resource management in multi-core processors, although the specific approach of managing channel stalls based on prior operation latency may be a novel aspect of this innovation.
=== What are the specific types of operations performed by the execution pipelines in this processor? The specific types of operations performed by the execution pipelines in this processor are not explicitly mentioned in the abstract. However, based on the context provided, it can be inferred that the execution pipelines are configured to handle various types of operations provided by the channel pipelines.
=== How does the dependency circuitry determine whether to stall an operation or deactivate a thread? The abstract mentions that the dependency circuitry determines whether to stall an operation or deactivate a thread based on status information for the prior operation from the execution pipelines. It would be interesting to know more about the specific criteria and algorithms used by the dependency circuitry to make these decisions.
Original Abstract Submitted
techniques are disclosed relating to channel stalls or deactivations based on the latency of prior operations. in some embodiments, a processor includes a plurality of channel pipelines for a plurality of channels and a plurality of execution pipelines shared by the channel pipelines and configured to perform different types of operations provided by the channel pipelines. first scheduler circuitry may assign threads to channels and second scheduler circuitry may assign an operation from a given channel to a given execution pipeline based on decode of an operation for that channel. dependency circuitry may, for a first operation that depends on a prior operation that uses one of the execution pipelines, determine, based on status information for the prior operation from the one of the execution pipelines, whether to stall the first operation or to deactivate a thread that includes the first operation from its assigned channel.
