Method and apparatus for inserting synchronization primitive, and related device

A method, comprising:

• obtaining a plurality of instruction pairs in a program, wherein each instruction pair comprises a source instruction and a destination instruction that have a dependency relationship, and the source instruction and the destination instruction in each instruction pair are executed by two different execution units;
• inserting a first virtual synchronization primitive into a first instruction pair, wherein the first virtual synchronization primitive comprises a first virtual identity (ID), and the first instruction pair is any of the plurality of instruction pairs;
• and
• determining, based on the first virtual synchronization primitive, a first synchronization primitive corresponding to the first instruction pair, wherein the first synchronization primitive comprises a first event ID, wherein a quantity of event IDs corresponding to two execution units that execute the first instruction pair is a preset fixed value, and a quantity of virtual IDs corresponding to the two execution units that execute the first instruction pair is greater than the quantity of the event IDs.

An accelerator card, comprising:

• a processor and a power supply circuit, wherein the power supply circuit is configured to supply power to the accelerator card, and the processor is configured to:
• obtain a plurality of instruction pairs in a program, wherein each instruction pair comprises a source instruction and a destination instruction that have a dependency relationship, and the source instruction and the destination instruction in each instruction pair are executed by two different execution units;
• insert a first virtual synchronization primitive into a first instruction pair, wherein the first virtual synchronization primitive comprises a first virtual identity (ID), and the first instruction pair is any one of the plurality of instruction pairs;
• and
• determine, based on the first virtual synchronization primitive, a first synchronization primitive corresponding to the first instruction pair, wherein the first synchronization primitive comprises a first event ID, a quantity of event IDs corresponding to two execution units that execute the first instruction pair is a preset fixed value, and a quantity of virtual IDs corresponding to the two execution units that execute the first instruction pair is greater than the quantity of the event IDs.

A computing device, comprising:

• a central processing unit, an accelerator card, and memory, wherein the memory stores instructions, the central processing unit or the accelerator card is configured to execute the instructions to:
• obtain a plurality of instruction pairs in a program, wherein each instruction pair comprises a source instruction and a destination instruction that have a dependency relationship, and the source instruction and the destination instruction in each instruction pair are executed by two different execution units;
• insert a first virtual synchronization primitive into a first instruction pair, wherein the first virtual synchronization primitive comprises a first virtual identity (ID), and the first instruction pair is any one of the plurality of instruction pairs;
• and
• determine, based on the first virtual synchronization primitive, a first synchronization primitive corresponding to the first instruction pair, wherein the first synchronization primitive comprises a first event ID, a quantity of event IDs corresponding to two execution units that execute the first instruction pair is a preset fixed value, and a quantity of virtual IDs corresponding to the two execution units that execute the first instruction pair is greater than the quantity of the event IDs.
