摘要： An embodiment may include circuitry to determine whether to issue at least one credit to at least one sender of at least one packet. The credit(s) may be to grant permission to the at least one sender to issue the at least one packet to at least one receiver of the at least one packet. The determination of whether to issue the credit(s) may be based, at least in part, upon whether a time in which the at least one receiver is in a relatively lower power state prior to issuance of the credit(s) is at least sufficient to provide at least a predetermined amount of reduction in power consumption. The relatively lower power state may be relative to a relatively higher power state of the at least one receiver that prevails at the issuance of the credit(s). Additionally or alternatively, the circuitry may be to receive such credit(s).

摘要： Methods and apparatus implementing Hardware/Software co-optimization to improve performance and energy for inter-VM communication for NFVs and other producer-consumer workloads. The apparatus include multi-core processors with multi-level cache hierarchies including and L1 and L2 cache for each core and a shared last-level cache (LLC). One or more machine-level instructions are provided for proactively demoting cachelines from lower cache levels to higher cache levels, including demoting cachelines from L1/L2 caches to an LLC. Techniques are also provided for implementing hardware/software co-optimization in multi-socket NUMA architecture system, wherein cachelines may be selectively demoted and pushed to an LLC in a remote socket. In addition, techniques are disclosure for implementing early snooping in multi-socket systems to reduce latency when accessing cachelines on remote sockets.

摘要： Methods, apparatus and systems for improved performance and energy efficiency of software-based routers. A software router running on a host computer system employing multiple Network Interface Controllers (NICs) maintains a routing table wherein packet flows are classified as managed flows (MFs) under which packets are received at and forwarded from the same NIC and unmanaged flows UFs under which packets are received at and forwarded from different NICs. Forwarding table data is employed by a NIC to facilitate packet identification and flow classification operations under which the NIC determines whether a received packet is an MF, UF, or an unclassified flow. Under various schemes, packet forwarding for MFs is handled by the software router architecture such that either only the packet header is copied into memory in the host or the entire packet forwarding is handled by the NIC.

摘要： Technologies for secure inter-virtual-machine shared memory communication include a computing device with hardware virtualization support. A virtual machine monitor (VMM) authenticates a view switch component of a target virtual machine. The VMM adds configures a secure memory view to access a shared memory segment. The shared memory segment may include memory pages of a source virtual machine or the VMM. The view switch component switches to the secure memory view without generating a virtual machine exit event, using the hardware virtualization support. The view switch component may switch to the secure memory view by modifying an extended page table (EPT) pointer. The target virtual machine accesses the shared memory segment via the secure memory view. The target virtual machine and the source virtual machine may coordinate ownership of memory pages using a secure view control structure stored in the shared memory segment. Other embodiments are described and claimed.
