    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. Other embodiments are described and claimed.

    Abstract: Computer-readable storage media, computing devices and methods associated with file cache management are discussed herein. In embodiments, a computing device may include a file cache and a file cache manager coupled with the file cache. The file cache manager may be configured to implement a context-aware eviction policy to identify a candidate file for deletion from the file cache, from a plurality of individual files contained within the file cache, based at least in part on file-level context information associated with the individual files. In embodiments, the file-level context information may include an indication of access recency and access frequency associated with the individual files. In such embodiments, identifying the candidate file for deletion from the file cache may be based, at least in part, on both the access recency and the access frequency of the individual files. Other embodiments may be described and/or claimed.

    Abstract: A network interface device (NID) may determine whether the received data units of the computer system are to be compressed before transmitting the data units. The NID may determine the compression energy value consumed to compress the first K1 data units and a second transmission energy value to transmit the compressed first K1 data units. The NID may then estimate a first transmission energy value that may be consumed by the NID to transmit uncompressed first K1 data units using the second transmission energy value. The NID may then use the first and second transmission energy value and the compression energy value to determine if the remaining (N−K1) data units of the first data stream.
