speculative execution

Speculative execution, in computer systems is doing work, the result of which may not be needed.

The same versioning facility can also be used for speculative execution.

Eager Haskell is designed around the idea of speculative execution.

The ability to issue instructions past branches which have yet to resolve is known as speculative execution.

In computer science, speculative execution is the execution of code, before being sure if the result will be needed.

Speculative execution coupled with an accurate branch predictor gives a large performance gain.

Speculative execution an optimization technique where a computer system performs some task that may not be actually needed.

With speculative execution enabled, however, a single task can be executed on multiple slave nodes.

It is a kind of speculative execution that occurs at the thread level as opposed to the instruction level.

Branch prediction is used with speculative execution.

Techniques such as branch prediction and speculative execution are used to reduce these branch penalties.

Modern instruction pipeline microprocessors use speculative execution to reduce the cost of conditional branch instructions.

Delayed exceptions, using a not a thing bit within the general purpose registers, allow speculative execution past possible exceptions.

One of the advantages of a direct mapped cache is that it allows simple and fast speculative execution.

The L2 cache is multi-versioned and supports transactional memory and speculative execution.

It would compute all possible answers, but the unneeded results would be canceled out (a kind of speculative execution).

Anticiparalleism is also known as speculative execution, continual computation or optimistic execution.

The incorporation of speculative execution into implementations of the Haskell programming language is a current research topic.

Speculative execution often provides modest performance increases by executing portions of code that may not be needed after a conditional operation completes.

The compiler is limited in issuing speculative execution instruction, since it requires hardware assistance to buffer the effects of speculatively-executed instructions.

Predicated execution is used to decrease the occurrence of branches and to increase the speculative execution of instructions.

The Alpha 21264 was a four-issue superscalar microprocessor with out-of-order execution and speculative execution.

The ALAT is used to store information related to advance load instructions, as part of the speculative execution process.

The Pentium Pro thus featured out of order execution, including speculative execution via register renaming.

It also makes hazard-avoiding techniques like branch prediction, speculative execution, and out-of-order execution crucial to maintaining high levels of performance.
