Memory management is the process of handling how much memory a program uses through different operations.Memory in CUnderstanding how memory works in C is important. When you create a basic variable, C will automatically reserve space for that variable. An int variable for example, will typically...
Memory management is part of a more general problem in programming called resource management. 内存管理是资源管理的一部分。 Every computer system has finite resources for your program to use. These include memory, open files, and network connections. If you use a resource, such as by opening a...
As the name suggests, ARC keeps track of your objects and decides which ones you meant to keep and which ones you didn't. It's a little like having a butler or personal assistant in your memory management. ARC跟踪你的对象,决定那个要保持,那个要取消。就像一个你的内存的私人助理。 When you...
分配器调用malloc分配大小为size * 20 * 2 +ROUNDUP(memory_allocated >> 4);,其中会有20个chunk是为申请的对象准备的,剩下的内存(并不会分割)作为战备池为以后的分配器行为做准备——这是一个很重要的概念,分配全程需要关注战备区pool的容量。 其中ROUNDUP()是对齐函数,memory_allocated是已经分配好的内存总量...
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。
