Abstract: Methods and apparatus are provided for reducing computer system boot up times in systems with composite HDD-SSD storage devices. Booting a computer system having a composite storage device that includes a magnetic storage device (HDD) and a solid state storage device (SSD) includes identifying boot data read from the magnetic storage device during an initial boot process, pinning the boot data to the solid state storage device, wherein pinning causes the boot data to be retained on the solid state storage device during movement of infrequently-used data from the solid state storage device to the magnetic storage device, and reading, by the computer system, the boot data from the solid state storage device during a subsequent boot process. Booting can also include moving infrequently accessed data from the solid state storage device to the magnetic storage device, and the boot data on the solid state storage device.

Abstract: Techniques are disclosed performing a power logging in a computer system at a sub-process level. An exemplary method includes an operating system of the computer system determining process information indicative of which sub-portions of one or more processes are running on the computer system at different points in time, as well as may determining power information for the computer system at different points in time. The operating system may the create, from the process information and the power information, a power log indicative of power usage of sub-portions of processes at a plurality of points in time. The power logging may extend to both core and non-core resources of the system. For non-core resources, the power usage may be estimated in some cases based on the type of non-core resource being called as well as parameters passed to the non-core resource.
