Abstract

Provided is a multithread processing device that includes a managing unit that assigns a free thread among a plurality of threads to at least one of a plurality of processes, and a processing unit that executes the one process to which the free thread is assigned by the managing unit, wherein, when a request is transmitted from a first process among the plurality of processes by the processing unit, the managing unit releases a thread assigned to the first process to be a free thread, and ends the first process, and when a response to the request is received by the processing unit, the managing unit assigns a free thread to a second process of executing a process related to the response among the plurality of processes.

Claims

1. A multithread processing device, comprising a processor, wherein

the processor assigns a free thread among a plurality of threads to at least one of a plurality of processes, and executes the one process to which the free thread is assigned;

when a request is transmitted by execution of a first process among the plurality of processes, the processor releases a thread assigned to the first process to be a free thread, and ends the first process; and

when a response to the request is received, the processor assigns a free thread to a second process of executing a process related to the response among the plurality of processes.

2. The multithread processing device according to claim 1, wherein

the processor adds identification information used to identify the second process and transmits the request;

and

when the response, to which the identification information added to the request is added by a transmission destination of the request, is received, the processor assigns a free thread to the second process based on the identification information added to the received response.

3. The multithread processing device according to claim 2, wherein

the identification information is an initial address of an object having the second process.

4. The multithread processing device according to claim 2, wherein

the identification information is a function pointer of a function of generating an object having the second process.

5. The multithread processing device according to claim 1, further comprising:

a thread pool that generates the plurality of threads in advance and manages the plurality of threads.

6. The multithread processing device according to claim 1, wherein

before the request is transmitted,

the processor assigns a process of receiving the response to the request as a reception standby thread to the free thread;

and

the processor starts a process of receiving the response through the reception standby thread.

7. The multithread processing device according to claim 1, wherein

the processor issues the request to another thread or another program executed by the processor;

and

in the execution of the other thread or the other program, the processor issues the response to the request.

8. A multithread processing system, comprising a multithread processing device and another device connected to perform communication with the multithread processing device, wherein

the multithread processing device includes a first processor;

the other device includes a second processor;

the first processor assigns a free thread among a plurality of threads to at least one of a plurality of processes, and executes the one process to which the free thread is assigned;

when a request is transmitted to the other device by execution of a first process among the plurality of processes, the first processor releases a thread assigned to the first process to be a free thread, and ends the first process;

the second processor transmits the response to the request received from the first processor to the multithread processing device; and

when the response to the request is received, the first processor assigns a free thread to a second process of executing a process related to the response among the plurality of processes.

9. A computer-readable recording medium having stored therein a multithread processing program for causing a computer to execute a process comprising:

assigning a free thread among a plurality of threads to at least one of a plurality of processes and executing the at least one process to which the free thread is assigned;

when a request is transmitted from a first process among the plurality of processes, releasing a thread assigned to the first process to be a free thread, and ending the first process; and

when a response to the request is received, assigning a free thread to a second process of executing a process related to the response among the plurality of processes.

10. The computer-readable recording medium according to claim 9, the process further comprising

adding identification information used to identify the second process to the request and transmitting the request, wherein

when the response, to which the identification information added to the request is added by a transmission destination of the request, is received, assigning a free thread to the second process based on the identification information added to the received response.

11. The computer-readable recording medium according to claim 10, wherein

the identification information is an initial address of an object having the second process.

12. The computer-readable recording medium according to claim 10, wherein

the identification information is a function pointer of a function of generating an object having the second process.

13. The computer-readable recording medium according to claim 9, wherein

a thread pool that generates the plurality of threads in advance and manages the plurality of threads is used in the assigning.

14. The computer-readable recording medium according to claim 9, the process further comprising:

before the request is transmitted,

assigning a process of receiving the response to the request as a reception standby thread to the free thread; and

starting a process of receiving the response through the reception standby thread.
