为什么作为一个连续的内存块存储树?
db2缓冲池由数个插槽(slot)的连续的内存组成。
在被加载到JVM中时,对象是由内存中的结构来表示的,结构占据了某个特定大小(它的域加上元数据)的连续的内存区域。
When loaded into the JVM, an object is represented by a structure in memory, occupying a continuous region of memory with a specific size (its fields plus metadata).
但是,共享内存段不能跨象限“拆分”,而应该保证是一个连续的地址空间。
However, a Shared memory segment cannot be "split" across quadrants and be guaranteed a contiguous address space.
在记忆棒增量分发数兆字节内存时,一次泄漏是微不足道的,但是连续操作数小时后,即使如此小的泄漏也会削弱应用程序。
This is tiny in a time when megabytes are given away in memory sticks as promotional items but, over hours of continuous operation, even such small losses can cripple an application.
DB 2需要一个连续的地址空间来作为共享内存区域。
DB2 needs a contiguous address space for the Shared memory area.
与传统的非分区环境不同的是,内存不再是一个连续空间。
The memory is no more a single contiguous space as it is for a traditional non-partitioned environment.
GC只能收缩从堆末尾开始的连续内存块,因此收缩堆可能需要进行压缩。
The GC can only contract contiguous blocks of memory from the end of the heap, so a compaction might be required to contract the heap.
共享内存段要求是连续的,因此不能跨越象限边界。
Shared memory segments are required to be contiguous, and therefore can not be split across quadrant boundaries.
主存中的每个位置都使用连续的数字地址编号,内存位置就使用这个地址来引用。
Every location in main memory is numbered with a sequential numeric address by which the memory location is referred.
这低于1.75GB的共享内存限制,并且每个数据库共享内存段可以安全地连续映射到一个象限。
This is well under the 1.75gb Shared memory limit, and each database Shared memory segment can safely map contiguously to a quadrant.
这有助于确保此表中的数据连续地缓存在内存中。
This helps ensure the data for this table is continuously cached in memory.
第一个分配程序是通用分配,可以满足针对任何数量的连续内存块的请求。
The first is a general-purpose allocation and can serve requests for any number of contiguous chunks.
希望分配了大量连续内存区域但这些内存不马上同时使用的程序常常结合使用保留内存和提交内存。
Programs that want to allocate a large and contiguous area of memory but don't need it all immediately often use a combination of reserved and committed memory.
如果CU是连续的(即完整地加载到内存中),则可以获得编译单元的高位、低位内存地址值。
If the CU is contiguous (that is, it is loaded into memory in one piece) then there are values for the low and high memory addresses for the unit.
即使有16gb的RAM,它也可能会被分段,从而没有一块连续的1.6 GB的内存。
Even with 16gb of RAM, it could be fragmented and there is not a contiguous 1.6gb of memory.
它还会导致系统看起来内存耗尽的情况,因为可用的内存碎片化,没有连续的可用内存。
It can also result in a situation where the system will seem to have run out of memory, because the available memory is fragmented and is not available contiguously.
IBMVM跟踪设施包含一个动态记录器(flightrecorder),它连续地将来自关键跟踪点子集的数据捕捉到内存缓冲区中。
The IBM VM tracing facility includes a flight recorder, which continuously captures data from a subset of key tracepoints to buffers in memory.
在任何合适的情况下使用PIPE作为两个连续动作节点的Input和Output,这将防止额外的上下文处理并可以将内存保持在一个较低的使用水平。
Whenever applicable use PIPE as Input and Output between two contiguous action nodes, this will prevent extra context processing and will keep memory usage down.
在虚拟存储系统中,一个固定长度的连续虚拟地址块,在分页操作过程中它作为一个单位在内存和磁盘之间来回复制。
In a virtual storage system, a fixed-length block of contiguous virtual addresses copied as a unit from memory to disk and back during paging operations.
位的应用程序可以直接访问4eb的虚拟内存,IntelItanium处理器提供了连续的线性地址空间。
A 64-bit application can directly access 4 exabytes of virtual memory, and the Intel Itanium processor provides a contiguous linear address space.
相邻页具有连续的页id且属于同一文件;这些页在内存中不一定相邻。
Adjacent pages have consecutive page IDs and are from the same file; the pages do not have to be contiguous in memory.
另外一个将它用于较大缓冲区的问题是,由于他分配了未分页内存,它也许会需要在连续的未分页内存中分配较大的一个块。
The other problem with using this for larger buffers is that since it allocates non-paged memory, it would need to allocate a large block of sequential non-paged memory.
和更多的变量,内存不是连续的当你分配一些内存(内存对齐),所以它可能需要更多的内存比你认为。
And for more variables, the memory isn't really contiguous when you allocate some memory (memory-alignment), so it could take more memory than you think it takes.
计算机的内存由一组连续编号的单元构成。
The memory of computer consists of a set of sequentially numbered locations.
并利用多线程及内存锁定分配方式保证打印程序连续流畅的运行,使得最终得到合格的打印图像。
The printing program works smoothly and continuously by using multithreading technology and memory lock allocation and therefore we get satisfied printing images.
