摘要： A system, method and computer program product for enhancing a real-time operating system (RTOS) with functionality normally associated with a general purpose operating system (GPOS). A hypervisor that is adapted to perform a real-time scheduling function supports concurrent execution of an RTOS and a GPOS on a system of shared hardware resources. The RTOS or its applications can utilize services provided by the GPOS. Such services may include one or more of file system organization, network communication, network management, database management, security, user-interface support and others. To enhance operational robustness and security, the hypervisor can be placed in read-only storage while maintaining the ability to update scheduling mechanisms. A programmable policy manager that is maintained in read-write storage can be used to dictate scheduling policy changes to the hypervisor as required to accommodate current needs.

摘要： A method for load balancing virtual machines includes accessing specification and utilization information for selected networked hardware platforms published on a network, the networked hardware platforms configured to run virtual machines and scoring the selected networked hardware platforms based on parameters from the utilization information to indicate resource availability for each of the selected networked hardware platforms. The method also includes removing a networked hardware platform from the selected networked hardware platforms based on a collocation policy to produce candidate platforms to receive a first virtual machine, wherein the collocation policy prohibits placement of the first virtual machine on the networked hardware platform based on at least one of consumer rules, provider rules, and industry rules.

摘要： A method for virtual machine management that includes establishing a first virtual machine on a hardware platform, performing a selected task on the first virtual machine and recording a first data set indicating a characteristic of the first virtual machine performing the selected task. The method also includes establishing a second virtual machine on the hardware platform, performing the selected task on the first and second virtual machines, recording a second data set indicating the characteristic of the first and second virtual machines performing the selected task and indicating acceptable data and unacceptable data within the first and second data sets. The method also includes creating and training a decision tree based on the acceptable and unacceptable data from the first and second data sets and inputting a third data set from a third virtual machine into the decision tree to determine if the third virtual machine is over-constrained.

摘要： To dynamically update an operating system, a new factory object may have one or more new and/or updated object instances. A corresponding old factory object is then located and its version is checked for compatibility. A dynamic update procedure is then executed, which includes (a) changing a factory reference pointer within the operating system from the old factory object to the new factory object. For the case of updated object instances, (b) hot swapping each old object instance for its corresponding updated object instance, and (c) removing the old factory object. This may be performed for multiple updated object instances in the new factory object, preferably each separately. For the case of new object instances, they are created by the new factory and pointers established to invoke them. A single factory object may include multiple updated objects from a class, and/or new object instances from different classes, and the update may be performed without the need to reboot the operating system.

摘要： Methods, systems, and media for reducing memory latency seen by processors by providing a measure of control over on-chip memory (OCM) management to software applications, implicitly and/or explicitly, via an operating system are contemplated. Many embodiments allow part of the OCM to be managed by software applications via an application program interface (API), and part managed by hardware. Thus, the software applications can provide guidance regarding address ranges to maintain close to the processor to reduce unnecessary latencies typically encountered when dependent upon cache controller policies. Several embodiments utilize a memory internal to the processor or on a processor node so the memory block used for this technique is referred to as OCM.
