Methods and apparatus to provide virtualized vector processing are described. In one embodiment, one or more operations corresponding to a virtual vector request are distributed to one or more processor cores for execution.

Virtual vector processing

Embodiments of the invention relate a hybrid hardware and software implementation of transactional memory accesses in a computer system. A processor including a transactional cache and a regular cache is utilized in a computer system that includes a policy manager to select one of a first mode (a hardware mode) or a second mode (a software mode) to implement transactional memory accesses. In the hardware mode the transactional cache is utilized to perform read and write memory operations and in the software mode the regular cache is utilized to perform read and write memory operations.

Hybrid hardware and software implementation of transactional memory access

Methods and apparatus to provide virtualized vector processing are disclosed. In one embodiment, a processor includes a decode unit to decode a first instruction into a decoded first instruction and a second instruction into a decoded second instruction, and an execution unit to: execute the decoded first instruction to cause allocation of a first portion of one or more operations corresponding to a virtual vector request to a first processor core, and generation of a first signal corresponding to a second portion of the one or more operations to cause allocation of the second portion to a second processor core, and execute the decoded second instruction to cause a first computational result corresponding to the first portion of the one or more operations and a second computational result corresponding to the second portion of the one or more operations to be aggregated and stored to a memory location.

In one embodiment, a processor may include a vector unit to perform operations on multiple data elements responsive to a single instruction, and a control unit coupled to the vector unit to provide the data elements to the vector unit, where the control unit is to enable an atomic vector operation to be performed on at least some of the data elements responsive to a first vector instruction to be executed under a first mask and a second vector instruction to be executed under a second mask. Other embodiments are described and claimed.

Vector instructions to enable efficient synchronization and parallel reduction operations

A technique to perform concurrent updates to a shared data structure. At least one embodiment of the invention concurrently stores copies of a data structure within a plurality of local caches, updates the local caches with a partial result of a computation distributed among a plurality of processing elements, and returns the partial results to combining logic in parallel, which combines the partial results into a final result.
