I'm using Rust, but Rust implements the C++ atomic memory model, so I will present my question in C++. I have an atomic object M. I want to issue an ...

I have a case where I need to ensure that an ISR cannot interact with a library when it is unloaded in an embedded system (ARM Cortex-M4 based). The ...

I think atomic.Load(addr) should equal *addr and atomic.Store(addr, newval) should equal *addr = newval. So why doing so(using *addr or *addr = newval ...

I'm having trouble in efficiently parallelizing the next line of code: This runs, I guess due to the omp for overhead, slower than this: Is ther ...

I saw already discussions about the synchronised question: How to prevent two threads entering the same section of code? They introduce some kind of s ...

Considering a 32-bit system (such as an ARM RISC MCU), how can one ensure that 16-bit variables are written/ read in an atomic way? Based on this doc, ...

I read S3 doc that PUT is atomic, in the sense there is never a partial write to an object. My naive intuition is that, there might be some underlying ...

Suppose I have some global: and a number of threads each with access to a that may be shared between threads. I would like to allocate free bloc ...

I am learning atomic operations supported by hardware. I know there are many atomic operations, for example, compare and swap(CAS)、fetch and add(FAA)、 ...

I am trying to do an atomic increment on a 64bit variable on a 32 bit system. I am trying to use atomic_fetch_add_explicit(&system_tick_counter_us ...

I recently came across the following code while learning about Reentrant Locks in Lock-Free Concurrency: However, it appears that there is a chance ...

According to an article in Jeff Preshing's blog: A release fence prevents the memory reordering of any read or write which precedes it in program ...

I am writing some code where a timer increments a global variable which maintains my internal system tick count. There are other api's like getCount() ...

I want to use GCC atomic memory access built-in functions in MSVC(v143) environment. How can i use them with MSVC?? I know that i can use them by ch ...

I am trying to atomically add a float value to a __half in CUDA 5.2. This architecture does support the __half data type and its conversion functions, ...

If you compile code such as you see that MSVC generates NOP padding after each memory load: Why is this? Is there any way to avoid it without re ...

I have been trying to use the $ function to extract a certain column from a list of data frames, and always get the same error. For reference, here i ...

I'm trying to implement an atomic tagged/packed pointer, for the sake of learning. I want to use the upper 16 bits for a uint16_t counter, and the lo ...

In the model-checked implementation of the CL-Deque, they use the following strategy to decrement the bottom pointer: So they load the bottom point ...

Quoting gnu: In practice, you can assume that int is atomic. You can also assume that pointer types are atomic; that is very convenient. Both of t ...
