摘要： A method to onboard a slave node to a high performance computing system that includes a fabric switch network that includes a fabric switch master and a group of slave nodes, wherein the fabric switch master is configured to route messages between slave nodes of the group comprising: receiving a fabric switch master address message, at an onboarding slave node, over an external network; providing an identification message, by the onboarding slave node, over the fabric switch network; receiving the identification message, at the fabric switch master, over the fabric switch network; providing the permission message, by the fabric switch master, over the fabric switch network; and receiving, a permission message, at the onboarding slave node, over the fabric switch network.

摘要： In one embodiment, an apparatus includes a first virtual machine (VM) including an encryption logic to encrypt first information. The encryption logic may include a first code block stored in a first execute-only region of a memory to encrypt the first information with a first key provisioned by a trusted agent, the first key stored in the first code block. The apparatus may further include a second VM including a decryption logic to decrypt the first information, and a shared buffer to enable secure communication of the encrypted first information from the first VM to the second VM, without involvement of the trusted agent. Other embodiments are described and claimed.

摘要： Generally, this disclosure provides systems, devices, methods and computer readable media for controlled memory view switching. The system may include a memory module comprising a shared address space between a first memory view and a second memory view. The system may also include a virtual machine monitor (VMM) to maintain a list of Controlled View Switch (CVS) descriptors. The system may further include a processor to receive a memory view switch request and to execute an instruction to save processor state information and switch from the first memory view to the second memory view, wherein the second memory view is specified by an extended page table pointer (EPTP) provided by one of the CVS descriptors.
