摘要： An autonomic computing environment is provided by sequestering one of a plurality of processor resources, partitioning a memory, and hiding an input/output (I/O) device. One processor resource is sequestered such that the sequestered processor resource is not exposed to the remaining processor resources as a processor resource. A memory region is partitioned to provide a service processing portion such that the sequestered processor resource has access to all of the memory region and the remaining processor resources have access to at least a portion of the memory region but do not have access to the service processing portion. A first I/O device is hidden such that the sequestered processor resource has access to the first I/O device and the remaining processor resources do not have access to the first I/O device.

摘要： Provided are a method, system, and article of manufacture. A network communication request is received at an offload application, wherein the offload application interfaces with a first network stack implemented in an operating system and a second network stack implemented in a hardware device. A determination is made if the network communication request can be processed by the second network stack. If the network communication request can be processed by the second network stack, then the network communication request is offloaded for processing to the hardware device.

摘要： A transport service provider provides a credit-based flow control scheme and is designed to operate over VI Architecture. The credit-based flow control scheme reduces overhead (e.g., reduces buffer copies and kernel processing) by relying upon the reliability properties of the underlying VI Architecture. If the number of send credits is sufficient, then the sender prepares and sends the packet. Otherwise, the sender sends a Credit Request and waits for a Credit Response. Upon receiving the corresponding Credit Response, the sender continues sending data packets. In response to a sender's Credit Request, the receiver sends the Credit Response only when it has enough receive credits (above a threshold value or low water mark).

摘要： In some embodiments, the invention involves a system to deprivilege components of a virtual machine monitor and enable deprivileged service virtual machines (SVMs) to handle selected trapped events. An embodiment of the invention is a hybrid VMM operating on a platform with hardware virtualization support. The hybrid VMM utilizes features from both hypervisor-based and host-based VMM architectures. In at least one embodiment, the functionality of a traditional VMM is partitioned into a small platform-dependent part called a micro-hypervisor (MH) and one or more platform-independent parts called service virtual machines (SVMs). The micro-hypervisor operates at a higher virtual machine (VM) privilege level than any SVM, while the SVM and other VMs may still have access to any instruction set architecture (ISA) privilege level. Other embodiments are described and claimed.
