US 2024/0403048 A1 · CATEGORIZED MEMORY OPERATIONS FOR SELECTIVE MEMORY FLUSHING

Abstract

Various embodiments include techniques for launching processing work in a computing system. The disclosed techniques include load and store operations that specify a category. The disclosed techniques further include barrier instructions that specify a category. A processing unit of the computing system executes a set of load and store operations that specify various categories. When the processor subsequently executes a barrier instruction that specifies a category, the barrier instruction waits for data for only load and store operations that specify the same category. After the barrier instruction completes execution, the processing unit can launch processes that are dependent on data from load and store operations of the specified category, even if data from load and store operations of other categories is still pending. As a result, the processing unit can launch processes as soon as the relevant data is available without waiting for nonrelevant data.

Dependent claims

A computer-implemented method for synchronizing processing work in a computing system, the method comprising:

executing a first memory operation that specifies a first category;
executing a first barrier instruction that specifies the first category;
determining that data associated with memory operations that specify the first category, including the first memory operation, is visible in a memory;
and
subsequent to determining that the data associated with the first memory operation is visible in the memory, setting a flag to enable a first process to execute on a processor while a second memory operation is pending, wherein the first process accesses the data associated with the first memory operation.

2 more elements

A system, comprising:

a memory storing instructions;
a first processor that is coupled to the memory and that executes processes for a second processor;
and
the second processor that is coupled to the first processor and the memory and, when executing the instructions:
executes a first memory operation that specifies a first category;
executes a first barrier instruction that specifies the first category;
determines that data associated with memory operations that specify the first category, including the first memory operation, is visible in a memory;
and
subsequent to determining that the data associated with the first memory operation is visible in the memory, sets a flag to enable a first process to execute on the first processor while a second memory operation is pending, wherein the first process accesses the data associated with the first memory operation.
