译者注:在内存管理领域,我们一般用「堆」指代用于分配动态内存的虚拟地址空间,而用「栈」指代用于分配静态内存的虚拟地址空间。具体到虚拟内存布局(Memory Layout),堆维护在通过brk系统调用申请的「Heap」及通过mmap系统调用申请的「Memory Mapping Segment」中;而栈维护在通过汇编栈指令动态调整的「Stack」中。在 Glibc...
Memory Mapping
Formatted binary files like HDF or TIFF that require customized readers are not good for memory-mapping. Describing the data contained in these files can be a very complex task. Also, you cannot access data directly from the mapped segment, but must instead create arrays to hold the data. Te...

ES2.0以后,正式默认启用Doc Values特性(1.x需要手动更改mapping开启),将field data在indexing time构建在磁盘上,经过一系列优化,可以达到比之前采用field data cache机制更好的性能。因此需要限制对field data cache的使用,最好是完全不用,可以极大释放heap压力。这里需要注意的是,排序、聚合字段必须为not analyzed。
A memory segment provides access to a contiguous region of memory. There are two kinds of memory segments: A heap segment is backed by, and provides access to, a region of memory inside the Java heap (an "on-heap" region). A native segment is backed by, and provides access to, a...

;SOLUTION: A polygon plotting command refers to specific information regarding a polygon to be plotted (301) and determines XY high-speed memory segment size (303). Namely, the use efficiency of a high-speed memory is optimized, a part where a polygon is present is plotted by using high-...
Memory Mapping and DMA This chapter delves into the area of Linux memory management, with an emphasis on techniques that are useful to the device driver writer. Many types of driver programming require some understanding of how the virtual memory subsystem works; the material we cover in this ...
