The present invention saves all process state, memory, and dependencies related to a software application to a snapshot image. Interprocess communication (IPC) mechanisms such as shared memory and semaphores must be preserved in the snapshot image as well. IPC mechanisms include any resource that is shared between two process or any communication mechanism or channel that allow two processes to communicate or interoperate is a form of IPC. Between snapshots, memory deltas are flushed to the snapshot image, so that only the modified-pages need be updated. Software modules are included to track usage of resources and their corresponding handles. At snapshot time, state is saved by querying the operating system kernel, the application snapshot / restore framework components, and the process management subsystem that allows applications to retrieve internal process-specific information not available through existing system calls. At restore time, the reverse sequence of steps for the snapshot procedure is followed and state is restored by making requests to the kernel, the application snapshot / restore framework, and the process management subsystem.

The very fast exception handling logic includes connection of an exception signal line to thread select logic, causing an exception signal to evoke a switch in thread and machine state. The switch in thread and machine state causes the processor to enter and to exit the exception handler immediately, without waiting to drain the pipeline or queues and without the inherent timing penalty of the operating system's software saving and restoring of registers.

A combined-hardware-and-software secure-platform interface to which operating systems and customized control programs interface within a computer system. The combined-hardware-and-software secure-platform interface employs a hardware platform that provides at least four privilege levels, non-privileged instructions, non-privileged registers, privileged instructions, privileged registers, and firmware interfaces. The combined-hardware-and-software secure-platform interface conceals all privileged instructions, privileged registers, and firmware interfaces and privileged registers from direct access by operating systems and custom control programs, providing to the operating systems and custom control programs the non-privileged instructions and non-privileged registers provided by the hardware platform as well as a set of callable software services. The callable services provide a set of secure-platform management services for operational control of hardware resources that neither exposes privileged instructions, privileged registers, nor firmware interfaces of the hardware nor simulates privileged instructions and privileged registers. The callable services also provide a set of security-management services that employ internally generated secret data, each compartmentalized security-management service managing internal secret data without exposing the internal secret data to computational entities other than the security-management service itself.

Datacenter clusters often employ live virtual machine (VM) migration to efficiently utilize cluster-wide resources. Gang migration refers to the simultaneous live migration of multiple VMs from one set of physical machines to another in response to events such as load spikes and imminent failures. Gang migration generates a large volume of network traffic and can overload the core network links and switches in a data center. The present technology reduces the network overhead of gang migration using global deduplication (GMGD). GMGD identifies and eliminates the retransmission of duplicate memory pages among VMs running on multiple physical machines in the cluster. A prototype GMGD reduces the network traffic on core links by up to 51% and the total migration time of VMs by up to 39% when compared to the default migration technique in QEMU / KVM, with reduced adverse performance impact on network-bound applications.

Transitions among schedulable entities executing in a computer system are tracked in computer hardware or in a virtual machine monitor. In one aspect, the schedulable entities are operating system processes and threads, virtual machines, and instruction streams executing on the hardware. In another aspect, the schedulable entities are processes or threads executing within the virtual machines under the control of the virtual machine monitor. The virtual machine monitor derives scheduling information from the transitions to enable a virtual machine system to guarantee adequate scheduling quality of service to real-time applications executing in virtual machines that contain both real-time and non-real-time applications. In still another aspect, a parent virtual machine monitor in a recursive virtualization system can use the scheduling information to schedule a child virtual machine monitor that controls multiple virtual machines.

The application template may be incorporated into a manifest listing other application templates and made available to users from a website.

A system and method for auto-polling a status register within a physical layer (PHY) interface to a local area network (LAN). The system includes a host CPU which needs to detect and service interrupts generated by a PHY device on the LAN which is coupled between a first transmission medium (such as copper or fiber cable) and a management interface to the system. The system further includes an auto-polling unit which monitors activity on the management interface of the PHY device. When the auto-polling unit detects a lack of activity on the management interface of the PHY for a predetermined interval, the auto-polling unit reads a first value from the PHY status register. This first status value is then compared to a previously stored value which corresponds to the last PHY status value read by the host CPU. If a mismatch is detected between these two values, an interrupt is generated to the CPU. In response to receiving the interrupt, auto-polling is suspended (to avoid changing the status data that caused the interrupt) and the CPU requests a read of the status value in the first register. In this manner, the CPU is able to access the status value which caused the interrupt and determine the appropriate course of action. This status read by the CPU also has the effect of clearing the interrupt. This system frees the CPU from having to continually poll the PHY status register to determine if a change in status has occurred.

A processor architecture containing multiple closely coupled processors in a form of symmetric multiprocessing system is provided. The special coupling mechanism allows it to speculatively execute multiple threads in parallel very efficiently. Generally, the operating system is responsible for scheduling various threads of execution among the available processors in a multiprocessor system. One problem with parallel multithreading is that the overhead involved in scheduling the threads for execution by the operating system is such that shorter segments of code cannot efficiently take advantage of parallel multithreading. Consequently, potential performance gains from parallel multithreading are not attainable. Additional circuitry is included in a form of symmetrical multiprocessing system which enables the scheduling and speculative execution of multiple threads on multiple processors without the involvement and inherent overhead of the operating system. Advantageously, parallel multithreaded execution is more efficient and performance may be improved.
