In computer architecture, a delay slot is an instruction slot being executed without the effects of a preceding instruction. [1] The most common form is a single arbitrary instruction located immediately after a branch instruction on a RISC or DSP architecture; this instruction will execute even if the preceding branch is taken.
In C++11 a std::future provides a read-only view. The value is set directly by using a std::promise , or set to the result of a function call using std::packaged_task or std::async . In the Dojo Toolkit 's Deferred API as of version 1.5, a consumer-only promise object represents a read-only view.
This is not the desired behavior, as (b) or (c) may have side effects, take a long time to compute, or throw errors. It is usually possible to introduce user-defined lazy control structures in eager languages as functions, though they may depart from the language's syntax for eager evaluation: Often the involved code bodies need to be wrapped ...
In computer programming, lazy initialization is the tactic of delaying the creation of an object, the calculation of a value, or some other expensive process until the first time it is needed.
Another example, in C++, uses the "angle bracket" characters < and > in the syntax for template specialization, but two consecutive > characters are interpreted as the right-shift operator >>. [4] Prior to C++11, the following code would produce a parse error, because the right-shift operator token is encountered instead of two right-angle ...

MESI in its naive, straightforward implementation exhibits two particular performance issues. First, when writing to an invalid cache line, there is a long delay while the line is fetched from other CPUs. Second, moving cache lines to the invalid state is time-consuming. To mitigate these delays, CPUs implement store buffers and invalidate ...
After months of delays, a federal judge in Washington, D.C., is scheduled to hold a hearing Thursday that could determine the trajectory of former President Donald Trump's election interference case.
