Determining command rate based on dropped commands

摘要

In one or more embodiments, one or more systems, devices, methods, and/or processes described can send, via an interconnect, a rate master command to at least one of multiple processing nodes; determine that a message indicating a dropped command, associated with the rate master command, is received; determine that a count, associated with dropped commands, satisfies a threshold; and provide, to the processing nodes via the interconnect, a signal indicating a command rate, in response to determining that the count satisfies the threshold. Moreover, the count can be incremented in response to determining that the message is received. The at least one of multiple processing nodes can receive, via the interconnect, the signal indicating the command rate and can utilize the command rate in issuing speculative commands, via the interconnect.

1. A data processing system, comprising:
an interconnect; a plurality of processing nodes coupled to the interconnect, wherein the plurality of processing nodes includes a first processing node including a first scheduler and a second processing node including a second scheduler; and wherein the first scheduler is configured to:
send, via the interconnect, a first rate master command to at least one of the plurality of processing nodes;determine that a first message is received, wherein the first message indicates that the first rate master command was dropped;determine that a count, associated with dropped commands, satisfies a threshold; andprovide, to the plurality of processing nodes via the interconnect, a signal indicating a command rate to be utilized by each of the plurality of processing nodes, in response to determining that the count satisfies the threshold; wherein the second scheduler is configured to detect the signal indicating the command rate, and in response thereto, cause the second processing node to utilize the command rate.
