Capacity-based multi-task scheduling method, apparatus and system

A task scheduling apparatus, comprising:

• a request information receiving unit configured to receive a request for acquiring a task sent by a task executing apparatus, the request carrying with a current load value and an available memory space of the task executing apparatus;
• a first deciding unit configure to decide whether the current load value is less than a threshold;
• a second deciding unit configure to decide whether there is a task to be assigned whose amount of memory requirement is less than or equal to the current available memory space of the task executing apparatus if the first deciding unit decides that the current load value is less than the threshold;
• and
• an assigning unit configure to assign the task whose amount of memory requirement is less than or equal to the current available memory space of the task executing apparatus to the task executing apparatus if the decision result of the second deciding unit is that there is a task to be assigned whose amount of memory requirement is less than or equal to the current available memory space of the task executing apparatus.
