The title is a bit of a detour. What I want to say is the global __device__ unsigned char data[64] defined when using Cuda; When a class of algorithms is parallelized, it is found that it is not necessary to copy data to the GPU every time the

Java memory ModelJava Virtual Machines The view in the specification defines a Java memory model (MODEL,JMM) that masks the access differences of various hardware and operating systems to enable Java programs to achieve consistent memory access

Main memory vs. working memory?The main goal of the Java memory model is to define the access rules for each variable in the program, that is , the underlying details of storing variables in the virtual machine to memory and extracting variable

Differences between semaphores and spin locks The spin lock does not cause the caller to sleep.If the spin lock has been maintained by another execution unit, the caller will keep repeating to check whether the lock holder has released the lock.

Sometimes in order to be efficient, sometimes in order to directly control the hardware, we have to write some modules directly in assembly language, and provide externally called interfaces to hide details. This is actually inline assembly. How to
