1. A method of reducing power consumption during execution of an application on a plurality of compute nodes, the method comprising:

  • powering up, during compute node initialization, only a portion of computer memory of a compute node;

    configuring an operating system for the compute node in the powered up portion of computer memory, including copying an image of the operating system to the powered up portion of computer memory;

    receiving, by the operating system, an instruction to load an application for execution;

    allocating, by the operating system, additional portions of computer memory to the application for use during execution;

    powering up the additional portions of computer memory allocated for use by the application during execution, wherein powering up the additional portions of computer memory allocated for use by the application during execution further comprises powering up the additional portions of computer memory upon requests to access those additional portions of computer memory; and

    loading, by the operating system, the application into the powered up additional portions of computer memory.
