Dispatching jobs for execution in parallel by multiple processors

A computer program product, the computer program product comprising one or more computer readable hardware storage devices having computer readable program code stored therein, said program code containing instructions executable by one or more processors to implement a method for dispatching a plurality of jobs for execution in a computing system comprising a plurality of processors configured to execute the jobs in parallel, said plurality of processors comprising the one or more processors, each processor of the plurality of processors being associated with a queue having a queue size equal to a maximum number of jobs that may be in the queue while the jobs in the queue are waiting to be executed by the processor associated with the queue, said method comprising:

• receiving, by the one or more processors, a request for execution of a new job of the plurality of jobs;
• assigning, by the one or more processors, the new job to a current class of a plurality of classes, wherein the jobs of different classes do not have execution dependencies;
• retrieving, by the one or more processors, an indication of a last processor of the processors of the current class to which a last job of jobs of the current class has been submitted for execution;
• retrieving, by the one or more processors, an indication of a delta number of the jobs being submitted for execution to the last processor of the current class after the last job of the current class;
• and
• submitting, by the one or more processors, the new job for execution to a submission processor of the plurality of processors, said submission processor being set to a selected processor of the plurality of processors according to a comparison between the delta number and the queue size of the last processor of the current class.

A computing system, comprising a plurality of processors that includes one or more processors, one or more memories, and one or more computer readable hardware storage devices, said one or more hardware storage device containing program code executable by the one or more processors via the one or more memories to implement a method for dispatching a plurality of jobs for execution in the computing system, said plurality of processors configured to execute the jobs in parallel, each processor of the plurality of processors being associated with a queue having a queue size equal to a maximum number of jobs that may be in the queue while the jobs in the queue are waiting to be executed by the processor associated with the queue, said method comprising:

• receiving, by the one or more processors, a request for execution of a new job of the plurality of jobs;
• assigning, by the one or more processors, the new job to a current class of a plurality of classes, wherein the jobs of different classes do not have execution dependencies;
• retrieving, by the one or more processors, an indication of a last processor of the processors of the current class to which a last job of jobs of the current class has been submitted for execution;
• retrieving, by the one or more processors, an indication of a delta number of the jobs being submitted for execution to the last processor of the current class after the last job of the current class;
• and
• submitting, by the one or more processors, the new job for execution to a submission processor of the plurality of processors, said submission processor being set to a selected processor of the plurality of processors according to a comparison between the delta number and the queue size of the last processor of the current class.
