Operational-task-oriented system and method for dynamically adjusting operational environment

A method for dynamically adjusting operational environment, applicable to a computer cluster, each of a plurality of operational nodes of said computer cluster installing a first operational system and a second operational system. and comprising steps of:

• a control node receiving an operational task including at least a first-type task and at least a second-type task, said first-type task being operated in said first operational system, and said second-type task being operated in said second operational system;
• when said plurality of operational nodes includes at least an idle operational node not performing operation, said control node judging whether said idle operational node operates in said first operational system or said second operational system;
• said control nodes estimating an estimated finish time of first-type task for operating said first-type task by said idle operational node running said first operational system and an estimated finish time of second-type task for operating said second-type task by said idle operational node running said second operational system;
• said control node comparing said estimated finish time of first-type task, said estimated finish time of second-type task, and an assigned finish time of operational task;
• when said estimated finish time of first-type task is greater than said assigned finish time of operational task and said estimated finish time of second-type task is less than said assigned finish time of operational task, said control node controls at least an idle node running said second operational system to restart for altering the operational system of said idle operational node to said first operational system;
• and
• when said estimated finish time of second-type task is greater than said assigned finish time of operational task and said estimated finish time of first-type task is less than said assigned finish time of operational task, said control node controls at least an idle node running said first operational system to restart for altering the operational system of said idle operational node to said second operational system.

• a control node receiving an operational task including at least a first-type task and at least a second-type task, said first-type task being operated in said first operational system, and said second-type task being operated in said second operational system;
• said control node estimating a time ratio of said first-type task in said operational task;
• when said plurality of operational nodes include a plurality of idle operational nodes not performing operation, said control node estimating an operational-system ratio of at least an idle operational node running said first operational system in said plurality of idle operational nodes;
• said control node comparing said time ratio and said operational-system ratio;
• when said time ratio is greater than said operational-system ratio, said control node controls at least an idle node running said second operational system to restart for altering the operational system of said idle operational node to said first operational system;
• and
• when said time ratio is less than said operational-system ratio, said control node controls at least an idle node running said first operational system to restart for altering the operational system of said idle operational node to said second operational system.
