摘要： A method comprises scheduling, by a weighted proportional-share virtual time processor scheduler, processor access to a first consumer during a time period in which a second consumer is blocked from processor access. When the second consumer becomes unblocked from processor access, the weighted proportional-share virtual time processor scheduler determines whether the length of the time period over which the second consumer was blocked from processor access exceeds a predefined time threshold. When determined that the length of the time period over which the second consumer was blocked from processor access does not exceed the predefined time threshold, then scheduler does not update the virtual time of the second consumer before scheduling processor access for the second consumer.

摘要： To train a virtual machine placement controller, the placement controller determines a new layout of virtual machines that is different from an existing layout of the virtual machines, according to criteria. The placement controller transmits the information relating to the new layout to a user interface. The placement controller receives feedback from the user interface, the received feedback indicating a user response to the new layout. The placement controller then modifies the criteria in response to the received feedback.

摘要： In various embodiments of the present invention, execution-state transitions occur in a first portion of a system, and a cumulative execution state for each process is maintained by a second portion of the system so that, when a second-portion routine is called, the second-portion routine can determine whether or not the current execution state is suitable for execution of the second-portion routine. In various embodiments, a callpoint log, allocated and maintained for each process, stores the cumulative execution state for the process. In one embodiment, the first portion is an operating system, and the second portion is a secure kernel, with the cumulative execution state used by the secure kernel to prevent unauthorized access by erroneously or maliciously invoked operating-system routines to secure kernel routines. In another embodiment, the cumulative execution state is used as a debugging tool by the second-portion routines to catch errors in the implementation of the first-portion routines.

摘要： Various aspects can be implemented for automated booking of advertising campaigns based on reach and frequency goals In general, one aspect can be a method that includes receiving campaign criteria including target reach and frequency for an advertising campaign. The method also includes allocating advertising spots based on the campaign criteria, and generating projected campaign reach and frequency based, at least in part, on the allocated advertising spots. The method further includes determining whether projected campaign reach and frequency sufficiently match target reach and frequency, and dynamically adjusting the allocation of advertising spots when the projected campaign reach and frequency do not sufficiently match the target reach and frequency. Other implementations of this aspect include corresponding systems, apparatus, and computer program products.

摘要： A method comprises observing communication through a virtualized interface between at least one virtual machine (VM) and a driver domain. Based on the observed communication through the virtualized interface, a weighted amount of communication between the VM and the driver domain is determined for each of the VM(s), wherein the weighted amount is based at least in part on at least one characteristic of the observed communication, such as directional flow and/or size of packets in the communication. Another method comprises evaluating CPU utilization of a target network driver domain in processing communications having different characteristics, and deriving corresponding weighting for the different communication characteristics. The derived weighting for the different communication characteristics are employed within a communication monitor that observes communication between virtual machines and the target network driver domain.
