Abstract

A method comprises: compiling the code segment with a compiler; and determining, based on an intermediate result of the compiling, a resource associated with a dedicated processing unit and for executing the code segment. As such, the resource required for executing a code segment may be determined quickly without actually executing the code segment and allocating or releasing the resource, which helps subsequent resource allocation and further brings about a better user experience.

First claim

What is claimed is:

1 . A method for determining a resource required for executing a code segment, the method comprising:
compiling the code segment with a compiler; and determining, based on an intermediate result of the compiling, a resource associated with a dedicated processing unit and for executing the code segment.

2 . The method according to claim 1 , wherein determining the resource comprises:
determining whether the intermediate result indicates a resource to be allocated for execution of the code segment; and in response to determining that the intermediate result indicates the resource to be allocated, recording, in a resource record, information related to the resource to be allocated.

3 . The method according to claim 2 , further comprising:
looking up, in the intermediate result, an instruction for allocating the resource to be allocated; and in response to finding the instruction,
deleting the instruction from the intermediate result, or
modifying the instruction in the intermediate result so as to avoid allocation of the resource to be allocated.

4 . The method according to claim 1 , wherein determining the resource comprises:
determining whether the intermediate result indicates a resource to be released for executing the code segment; and in response to determining that the intermediate result indicates the resource to be released, removing information related to the resource to be released from the resource record.

5 . The method according to claim 4 , further comprising:
looking up, in the intermediate result, an instruction for releasing the resource to be released; and in response to finding the instruction,
deleting the instruction from the intermediate result, or
modifying the instruction in the intermediate result so as to avoid release of the resource to be released.

6 . The method according to claim 1 , wherein determining the resource comprises:
obtaining an amount of resource recorded in a resource record during the compiling; and determining, based on the recorded amount of resource, the resource required for executing the code segment.

7 . The method according to any of claim 1 , wherein the resource comprises at least one of a computing resource and a storage resource in a dedicated processing unit.

8 . A device for determining a resource required for executing a code segment, comprising:
at least one processing unit; at least one memory, coupled to the at least one processing unit and storing instructions executed by the at least one processing unit, the instructions, when executed by the at least one processing unit, causing the device to perform acts, including: compiling the code segment with a compiler; and determining, based on an intermediate result of the compiling, a resource associated with a dedicated processing unit and for executing the code segment.

9 . The device according to claim 8 , wherein determining the resource comprises:
determining whether the intermediate result indicates a resource to be allocated for execution of the code segment; and in response to determining that the intermediate result indicates the resource to be allocated, recording, in a resource record, information related to the resource to be allocated.

10 . The device according to claim 9 , wherein the acts further comprise:
looking up, in the intermediate result, an instruction for allocating the resource to be allocated; and in response to finding the instruction,
deleting the instruction from the intermediate result, or
modifying the instruction in the intermediate result so as to avoid allocation of the resource to be allocated.

11 . The device according to claim 8 , wherein determining the resource comprises:
determining whether the intermediate result indicates a resource to be released for executing the code segment; and in response to determining that the intermediate result indicates the resource to be released, removing information related to the resource to be released from the resource record.

12 . The device according to claim 11 , wherein the acts further comprise:
looking up, in the intermediate result, an instruction for releasing the resource to be released; and in response to finding the instruction,
deleting the instruction from the intermediate result, or
modifying the instruction in the intermediate result so as to avoid release of the resource to be released.

13 . The device according to claim 8 , wherein determining the resource comprises:
obtaining an amount of resource recorded in a resource record during the compiling; and determining, based on the recorded amount of resource, the resource required for executing the code segment.

14 . The device according to claim 8 , wherein the resource comprises at least one of a computing resource and a storage resource in a dedicated processing unit.

15 . A computer program product being tangibly stored on a non-transient computer readable medium and comprising machine executable instructions which, when being executed, causing a machine to perform steps of:
compiling the code segment with a compiler; and determining, based on an intermediate result of the compiling, a resource associated with a dedicated processing unit and for executing the code segment.

16 . The computer program product according to claim 15 , wherein determining the resource comprises:
determining whether the intermediate result indicates a resource to be allocated for execution of the code segment; and in response to determining that the intermediate result indicates the resource to be allocated, recording, in a resource record, information related to the resource to be allocated.

17 . The computer program product according to claim 16 , further comprising:
looking up, in the intermediate result, an instruction for allocating the resource to be allocated; and in response to finding the instruction,
deleting the instruction from the intermediate result, or
modifying the instruction in the intermediate result so as to avoid allocation of the resource to be allocated.

18 . The computer program product according to claim 15 , wherein determining the resource comprises:
determining whether the intermediate result indicates a resource to be released for executing the code segment; and in response to determining that the intermediate result indicates the resource to be released, removing information related to the resource to be released from the resource record.

19 . The computer program product according to claim 18 , further comprising:
looking up, in the intermediate result, an instruction for releasing the resource to be released; and in response to finding the instruction,
deleting the instruction from the intermediate result, or
modifying the instruction in the intermediate result so as to avoid release of the resource to be released.

20 . The computer program product according to claim 15 , wherein determining the resource comprises:
obtaining an amount of resource recorded in a resource record during the compiling; and determining, based on the recorded amount of resource, the resource required for executing the code segment.
