    摘要: A method and computer program product for improving storage efficiency for a digital video recorder. In one embodiment, a determination is made as to whether television programming is being presented on a high definition channel or a standard definition channel. The television programming is recorded using the digital video recorder responsive to determining that the television programming is being presented on a standard definition channel without making any resolution changes to the television programming. A determination is made as to whether the content of the television programming originates in high definition or standard definition. When the television programming originates in standard definition, a determination is made as to whether a corresponding standard definition channel is available. Responsive to determining the corresponding channel is available, the television programming is recorded in standard definition from the corresponding channel. Otherwise, the television programming is downscaled on the high definition channel to a standard definition resolution.

    摘要: A generalized on-line solution for achieving transparent binary optimization using pre-existing profiling facilities and virtual memory remapping of text regions. An optimization environment is initialized which comprises a debugger program, a profiling facility, and an optimizer. A running target program is attached to the debugger program, wherein the debugger program monitors process execution of the target program. Responsive to monitoring the running target program, profile data of the running target program is collected using the profiling facility. The profile data is provided to the optimizer, wherein the optimizer analyzes the profile data and existing code of the running target program. Responsive to a determination to optimize the existing code based on the profile data, optimized code is generated for the running target program. The optimized code is provided to the debugger program, wherein the debugger program inserts the optimized code into a virtual address space of the running target program.

    摘要: A hypervisor receives a memory page checksum from a guest operating system, which corresponds to a page of memory utilized by the guest. Next, the hypervisor proceeds through a series of steps to detect that the memory page checksum matches a checksum value included in a checksum entry item, which includes an identifier of a different guest. In turn, the hypervisor shares the page of memory between the guest and the different guest in response to detecting that the memory page checksum matches the checksum value included the checksum entry item.

    摘要: A computer implemented method, apparatus, and computer usable program product for binding a process to a selected node of a multi-node system. Input/output activity statistics for a process are retrieved from a set of probes. The set of probes detects a flow of data through an input/output device utilized by the process. A topology of the multi-node system that comprises a location of the input/output device is identified. A node is selected according to a decision policy to form a selected node. The process is bound to the selected node according to the decision policy.
