Generating job alert

A system for generating a computer processing job alert, the system comprising:

• a relationship determining unit configured to
• determine a historical job by sampling an input of a target job, wherein the target job has an intermediate task, the historical job has a historical intermediate task, and the intermediate task has the same processing logic with the historical intermediate task, and
• determine a relationship of the input and output of the target job in at least one stage of a plurality of stages through analyzing the historical job, wherein the target job is to be processed in parallel in the at least one stage,
• wherein the relationship determining unit includes:
• an association determining unit configured to determine an association between input data and output data of the intermediate task of the target job based on an input data size and an output data size of the historical intermediate task;
• a resource overhead calculating unit including a processor and configured to calculate a computing resource overhead prediction associated with the target job based on the relationship of input and output;
• an alert generating unit configured to generate a proactive alert for the target job in response to the resource overhead prediction exceeding a predetermined threshold indicating an insufficiency of system parameters for performing the target job;
• and
• a processor configured to process the target job with adjusted system parameters to prevent exceeding a resource overhead.
