Interpreted Languages, logically execute each line by applying the state available before the line and hence get the state after the execution. I wond ...
I'm adding a profiler to an existing evaluator. The evaluator is implemented in c++ (std17 x86 msvc) and I need to store 3 int32, 1 uint16 and 1 uint8 ...
According to the Java Memory Model (JMM): A program is correctly synchronized if and only if all sequentially consistent executions are free of da ...
When dealing with happens before, I see it as about dealing with memory ordering and whether some memory ordering is valid with program order. For exa ...
Created a small rust program to understand the memory allocation. Just wanted to understand if the data types use the memory area they are supposed to ...
In the book C++ Concurrency in Action, the author gives this example when talking about suquential consistency, and says assert can never fire, beca ...
In the book C++ Concurrency in Action, when introducing relaxed ordering, the author says: Relaxed operations on different variables can be freely ...
P0668R5 made some changes to the sequentially-consistent ordering. The following example, from the proposal (also from cppreference), describes the mo ...

Suppose I have two pages that map to the same physical memory. Would an acquire operation (or fence) on a virtual address in one page properly synchro ...
i have a question on the go memory model. in the last example: In my opnion,reads and writes of values with a single machine word is a atomic behav ...
In the J. Sorin book "Primer on Memory Consistency and Cache Coherence" I found the next paragaph about RMW optimistion in the SC model: More aggr ...
In C++11 and C11 it is possible to use 8- and 16-bit atomics. Are there any pitfalls of using them on actual modern 32- and 64-bit CPUs? Are they lock ...
I've read this Q&A: What is the significance of 'strongly happens before' compared to '(simply) happens before'? The author gives an outline of a ...
All examples I've ever seen on when cache coherence is relevant are code examples that are data races (two cores simultaneously write to the same memo ...
I've been reading this post of Jeff Preshing about The Synchronizes-With Relation, and also the "Release-Acquire Ordering" section in the std::memory_ ...
I am facing the following problem: My program uses the concept of "tasks", where a task exists of code (functions) that together make up a critical a ...
