Multi-Thread Concurrency Management Method and Related Apparatus

A multi-thread concurrency management apparatus, comprising:

• at least one memory configured to store code instructions;
• and
• at least one processor coupled to the at least one memory and configured to execute the code instructions to cause the multi-thread concurrency management apparatus to:
• divide a target global variable into variable sub-areas, wherein the target global variable is for controlling threads to access target data, and wherein each of the variable sub-areas comprises flag bits, and wherein the threads are for applying for a permission to read the target data;
• group the threads into thread groups;
• identify a target thread group from among the thread groups, a target thread from among the threads in the target thread group, a target variable sub-area from among the variable sub-areas, and a target flag bit from among the flag bits in the target variable sub-area;
• authorize the target thread to modify a flag bit of the one or more flag bits;
• and
• allow the target thread to read the target data when the target thread successfully modifies the target flag bit.

A computer program product comprising instructions that are stored on a computer-readable medium and that, when executed by at least one processor, cause multi-thread concurrency management apparatus to:

• divide a target global variable into variable sub-areas, wherein the target global variable is for controlling threads to access target data, and wherein each of the variable sub-areas comprises flag bits, and wherein the threads are for applying for a permission to read the target data;
• group the threads into thread groups;
• identify a target thread group from among the thread groups, a target thread from among the threads in the target thread group, a target variable sub-area from among the variable sub-areas, and a target flag bit from among the flag bits in the target variable sub-area;
• authorize the target thread to modify a flag bit of the one or more flag bits;
• and allow the target thread to read the target data when the target thread successfully modifies the target flag bit.
