注:若不用#pragma pack(1)和#pragma pack()括起来,则sample按编译器默认方式对齐(成员中size最大的那个)。即按8字节(double)对齐,则sizeof(sample)==16.成员char a占了8个字节(其中7个是空字节);若用#pragma pack(1),则sample按1字节方式对齐sizeof(sample)==9.(无空字节),比较节省空间啦,有些场和...
相当于 #pragma pack (push,4) #pragma pack (1) 作用:调整结构体的边界对齐,让其以一个字节对齐;<使结构体按1字节方式对齐> #pragma pack () 例如: #pragma pack(1) struct sample { char a; double b; }; #pragma pack() 注:若不用#pragma pack(1)和#pragma pack()括起来,则sample按编译器默...
Prefetching can often overlap memory latency with computation for array-based numeric applications. However, prefetching for pointer-intensive applications still remains a challenging problem. Prefetching linked data structures (LDS) is difficult because the address sequence of LDS traversal does not present...
If an end user is currently runningv1, and they query the server for an update, it will respond withv3(since that's the latest), but it will dynamically convert the release to mandatory, since a mandatory update was released in between. This behavior is important since the code contained ...
This paper measures the extent to which this variation in national-brand purchase shares depends on store-specific supply decisions, which are traditionally within the purview of trade marketing. We first demonstrate the extent to which purchase shares of the top two national brands across 6 ...

对于任何一个数据处理系统来说,可以简单抽象为2大部分:数据源系统和后台处理系统(为了方便后续文字阐述,这里将数据源部分跟数据处理部分在逻辑上拆分为两个不同的系统)。而后台处理系统都可以简单的抽象划分为3个层次:数据接入层、数据计算处理层和数据存储层。
