As the name implies, an in-memory database resides entirely in main memory rather than on disk, making data access an order of magnitude faster than with conventional, disk-based databases.
顾名思义，内存中数据库完全驻留在主存中，而不是磁盘上，这使得数据访问比传统的基于磁盘的数据块要快一个数量级。
When strdup is called in foo , the namestr variable value is overwritten, thereby losing the pointer to the memory allocated in main , and that causes the leak.
当strdup在foo中被调用，这个namestr变量值就会被覆写，从而丢失main中内存分配的指针，导致渗漏。

当这个内存分配在main后，namestr变量会在什么地方被使用和编写呢？
The other main type of processor architecture, CISC (the x86 processor being a popular CISC instruction set), allows for memory access in nearly every instruction.
另外一种主要的处理器体系结构CISC (x86处理器就是一种流行的CISC指令集)几乎允许在每条指令中进行内存访问。
When a program writes to memory, the processor only modifies the line in the cache, but does not update main memory.
当一个程序写入存储，处理器仅仅只会修改缓存线，而不会更新主要的存储内容。
If the data or instruction is not present in the cache, or if the cache line is invalidated, the CPU updates its cache by reading the data from the main memory.
如果数据或指令没有出现在高速缓存中，或者如果高速缓存线路无效的时候，CPU通过从主存储器中读数据来更新它的高速缓存。
For example, a compiler may choose to optimize a loop index variable by storing it in a register, or the cache may delay flushing a new value of a variable to main memory until a more opportune time.
例如，编译器为了优化一个循环索引变量，可能会选择把它存储到一个寄存器中，或者缓存会延迟到一个更适合的时间，才把一个新的变量值存入主存。
Because data is replicated across the cluster, each server in the cluster has enough main memory to store the entire context data.
由于数据在整个集群中进行复制，集群中的每个服务器都有足够的主存来存储整个上下文数据。
As the word and letters are entered, they are displayed in the CRT screen and stored in main memory of the personal computer.
当字母和单词被输入以后，它们显示在阴极射线管屏幕上，并且存储在计算机在主存中。
When the program execution leads to instructions not in the cache, then the instructions need to be fetched from the main memory and the microprocessor has to stop and wait.
当程序执行导致命令不能从快取内存中找到时，需要从主内存中找到命令，那是微处理器就停下来等待。
However, remember that they point to memory in the main storage of the application (an effective address), not to the SPE's local store.
但请记住它们指向在应用程序主存储内的内存(有效地址)，而非到SPE的本地存储。
You can use it when the amount of data to be stored in the cache exceeds the main memory of the application server systems.
当要在缓存中存储的数据量超过应用程序服务器系统的主存时，您就可以使用此功能。
In addition, the middleware can manage these caches to reduce pressure on main memory and copy them between processors to improve workload management.
此外，中间件还可以对这些缓存进行管理，从而减少主存的压力，并能在处理器之间复制这些信息，以改善工作负载管理。
The existing JMM says that volatile reads and writes are to go directly to main memory, prohibiting caching values in registers and bypassing processor-specific caches.
现有JMM 表明易失性的读和写是直接和主存打交道的，这样避免了把值存储到寄存器或者绕过处理器特定的缓存。
The main reason is that DB2 is very aggressive in trying to keep a hot cache (essentially, the data your application needs in memory).
主要原因是，DB2在努力保持热缓存(实际上是在内存中应用程序所需的数据)方面非常主动。
The cache is generally allowed to write variables back to main memory in a different order than they were written by the program.
通常允许缓存以与程序写入变量时所不相同的次序把变量存入主存。
This request asks for sizeof(data) bytes of data copied from the address in main memory denoted by argp to be copied into the object data.
这个请求会要求将sizeof(data)字节的数据从 argp所指向的主存地址处拷贝到 data 对象中。
