  • Publication number: 20170032486
    Abstract: In accordance with some embodiments, a continuous thread is operated on the graphics processing unit. A continuous thread is launched one time from the central processing unit and then it runs continuously until an application on the central processing unit decides to terminate the thread. For example, the application may decide to terminate the thread in one of a variety of situations which may be programmed in advance. For example, upon error detection, a desire to change the way that the thread on the graphics processing unit operates, or in power off, the thread may terminate. But unless actively terminated by the central processing unit, the continuous thread generally runs uninterrupted.

  • Patent number: 9454497
    Abstract: 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.

  • Patent number: 9450780
    Abstract: 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.
