全局内存通过主机的cudaMalloc进行分配,通过主机的cudaFree进行释放。全局内存的访问以32-byte,64-byte或128-byte为单位的内存事务 memory transaction 进行。 接下来会详细讨论cuda的全局内存管理 memory management,以后将讨论内存访问模式 memory access pattern 等内容。 内存管理 memory management 分配与释放全局内存 a...
这是一个学习笔记,PDF可以从这里下载,这个repo 是 fork 自mapengfei-nwpu/ProfessionalCUDACProgrammingChapter 4 Global Memory - Memory Management 因为主机和设备的代码不能访问位于其外的内存,需要 CUDA Runtime 来居中协调。所以如何分配和释放设备内存,以及如何在主机和设备之间高效的传输数据就是一个需要注意的问...
Memory Management ❮ PreviousNext ❯ Memory management is the process of handling how much memory a program uses through different operations. Memory in C Understanding how memory works in C is important. When you create a basic variable, C will automatically reserve space for that variable. ...

When new is used to gain a block of memory the size reserved by the operating system may be bigger than your request, but never smaller. Because of this and the fact that delete doesn't immediately return the memory to the operating system, when you inspect the whole memory that your ...
本文翻译自Advanced Memory Management Programming Guide 一、关于内存管理 Although memory management is typically considered at the level of an individual object, your goal is actually to manageobject graphs. You want to make sure that you have no more objects in memory than you actually need. ...
(Java, Python, and Perl) have automated memory management. This ranges from Python’s simple reference-counted model to Java’s sophisticated garbage collector. To the programmer, however, the final result is nearly always the same: no more worrying about memory errors. Why, then, even bother...
