Abstract: Techniques for remote SGX enclave authentication are described. An attestation service may be used to attest that an enclave was successfully established on a Software Guard Extensions (SGX) enabled platform. Further, an attestation service may, in embodiments, be used as a notary system to attest that a public-key certificate was generated by a particular SGX enclave and, therefore, may be trusted by other remote enclaves for authentication. In an embodiment, a client-side SGX enclave may generate a public-private key pair (SK, PK), compute a cryptographic hash H of PK, create a report R containing H, obtain a quote Q on the report R from a quoting enclave component, obtain remote attestation response RA from an attestation service, and broadcast RA and PK to one or more server side SGX enclaves. Other embodiments are described and claimed.

Abstract: In an embodiment, a method is provided. The method includes managing user-level threads on a first instruction sequencer in response to executing user-level instructions on a second instruction sequencer that is under control of an application level program. A first user-level thread is run on the second instruction sequencer and contains one or more user level instructions. A first user level instruction has at least 1) a field that makes reference to one or more instruction sequencers or 2) implicitly references with a pointer to code that specifically addresses one or more instruction sequencers when the code is executed.

Abstract: In one embodiment, the present invention includes a method for directly communicating between an accelerator and an instruction sequencer coupled thereto, where the accelerator is a heterogeneous resource with respect to the instruction sequencer. An interface may be used to provide the communication between these resources. Via such a communication mechanism a user-level application may directly communicate with the accelerator without operating system support. Further, the instruction sequencer and the accelerator may perform operations in parallel. Other embodiments are described and claimed.

Abstract: An embodiment of the present invention is a technique to provide a real-time threading service to an application in a multi-core environment. An executive is launched, within a most privilege level of an operating system (OS), on a real-time core in the multi-core environment. The real-time core is sequestered from the OS. A real-time thread is created in a least privilege level on the real-time core for an application using a library. The library is loaded by the application. The real-time thread shares a virtual address space with the application.

Abstract: Disclosed are embodiments of a system, methods and mechanism for management and translation of mapping between logical sequencer addresses and physical or logical sequencers in a multi-sequencer multithreading system. A mapping manager may manage assignment and mapping of logical sequencer addresses or pages to actual sequencers or frames of the system. Rationing logic associated with the mapping manager may take into account sequencer attributes when such mapping is performed Relocation logic associated with the mapping manager may manage spill and fill of context information to/from a backing store when re-mapping actual sequencers. Sequencers may be allocated singly, or may be allocated as part of partitioned blocks. The mapping manager may also include translation logic that provides an identifier for the mapped sequencer each time a logical sequencer address is used in a user program. Other embodiments are also described and claimed.

Abstract: Method, apparatus and system embodiments to schedule OS-independent “shreds” without intervention of an operating system. For at least one embodiment, the shred is scheduled for execution by a scheduler routine rather than the operating system. A scheduler routine may run on each enabled sequencer. The schedulers may retrieve shred descriptors from a queue system. The sequencer associated with the scheduler may then execute the shred described by the descriptor. Other embodiments are also described and claimed.

Abstract: Method, apparatus and system embodiments to provide user-level creation, control and synchronization of OS-invisible “shreds” of execution via an abstraction layer for a system that includes one or more sequencers that are sequestered from operating system control. For at least one embodiment, the abstraction layer provides sequestration logic, proxy execution logic, transition detection and shred suspension logic, and sequencer arithmetic logic. Other embodiments are also described and claimed.
