Scheduling and/or organizing task execution for a target computing platform

An apparatus effective to schedule a task to be executed on a computing platform, where the computing platform is configured to operate at two or more operating speeds, the apparatus comprising:

• a processor effective to:
• determine respective lengths of clock cycles at the two or more operating speeds;
• determine, at least partially based on the respective lengths of the clock cycles, a number of clock cycles on the computing platform to complete the task;
• determine, at least partially based on the number of clock cycles to complete the task, a virtual operating speed of the computing platform to perform the task by or before a completion deadline of the task so as to achieve a particular energy consumption,
• wherein the virtual operating speed is based on operation of the computing platform at a first operating speed for a first specified time and at a second operating speed for a second specified time,
• wherein the first, virtual and second operating speeds are on a convex enclosure curve that is at least partially based on energy consumption for the two or more operating speeds,
• wherein the virtual operating speed is higher than the first operating speed but lower than the second operating speed, and
• wherein the first and second operating speeds are two closest operating speeds to the virtual operating speed;
• and
• schedule the task to be executed on the computing platform at the virtual operating speed.

A non-transitory computer-readable medium that includes computer-executable instructions stored thereon to schedule a task to be executed on a computing platform, where the computing platform is capable to operate at two or more operating speeds, the instructions being executable by one or more processors to perform or cause to be performed:

• determining, at least partially based on respective lengths of clock cycles at the two or more operating speeds, a number of clock cycles on the computing platform to complete the task;
• determining, at least partially based on the number of clock cycles to complete the task, a virtual operating speed of the computing platform to perform the task by or before a completion deadline of the task so as to achieve a particular energy consumption,
• wherein the virtual operating speed is based on operation of the computing platform at a first operating speed for a first specified time and at a second operating speed for a second specified time,
• wherein the first, virtual, and second operating speeds are on a convex enclosure curve that is at least partially based on energy consumption for the two or more operating speeds,
• wherein the virtual operating speed is higher than the first operating speed but lower than the second operating speed, and
• wherein the first and second operating speeds are two closest operating speeds to the virtual operating speed;
• and
• scheduling the task to be executed on the computing platform at the virtual operating speed.
