Method, electronic device, and computer program product for processing computing job

An electronic device, comprising:

• a processor;
• and
• a memory coupled to the processor and having instructions stored therein, wherein the instructions, when executed by the processor, cause the device to execute actions comprising:
• determining a first dependency relationship between a plurality of computing tasks included in a to-be-processed computing job;
• determining, based on the first dependency relationship and demands of the plurality of computing tasks for computing resources, a group of computing tasks for combination from the plurality of computing tasks;
• and
• combining the group of computing tasks into a target computing task;
• wherein determining the group of computing tasks from the plurality of computing tasks comprises:
• determining, for each computing task of the plurality of computing tasks and based on the first dependency relationship, the number of computing tasks associated with at least one of an input or an output of a corresponding computing task;
• determining a first group of candidate tasks from the plurality of computing tasks, wherein the number determined for each candidate task is less than a threshold number;
• determining, based on demands of the first group of candidate tasks for the computing resources, a second group of candidate tasks for combination from the first group of candidate tasks;
• and
• selecting the group of computing tasks from the second group of candidate tasks.

A computer program product tangibly stored in a non-transitory computer-readable medium and comprising machine-executable instructions, wherein the machine-executable instructions, when executed, cause a machine to execute a method for processing a computing job, the method comprising:

• determining a first dependency relationship between a plurality of computing tasks included in a to-be-processed computing job;
• determining, based on the first dependency relationship and demands of the plurality of computing tasks for computing resources, a group of computing tasks for combination from the plurality of computing tasks;
• and
• combining the group of computing tasks into a target computing task;
• wherein determining the group of computing tasks from the plurality of computing tasks comprises:
• determining, for each computing task of the plurality of computing tasks and based on the first dependency relationship, the number of computing tasks associated with at least one of an input or an output of a corresponding computing task;
• determining a first group of candidate tasks from the plurality of computing tasks, wherein the number determined for each candidate task is less than a threshold number;
• determining, based on demands of the first group of candidate tasks for the computing resources, a second group of candidate tasks for combination from the first group of candidate tasks;
• and
• selecting the group of computing tasks from the second group of candidate tasks.
