Article Title: LinuxSLUB distributor details. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Kernel Object Buffer Management During Linux kernel running, some kernel data structures (objects) are often used ). For example, when a thread of a process opens a file for the first time, the kernel needs to allocate a d

Fast and Effective Memory distributor for small memory blocks Translated by znrobinson Guo shilong Introduction Dynamic memory allocation is interesting. When calling malloc/free, most people will not consider the associated costs. Heap-based memory allocation is mentioned. In order to re-apply for and re-use the memory, the management of memory blocks must carry out a lot of notes, which will take a CPU cycle. When we try to write efficient code, th

Note: memory management is always the red-light area of the C/C ++ program. There are two focuses on memory management. One is the correct use of memory. For example, new and delete in C ++ should appear in pairs and use raiI to manage memory resources, auto_ptr and other aspects, many C/C ++ books use the introduction of skills. The other is the implementation of memory management, such as the slab distributor of the Linux kernel, Allocator implement

Article Title: slab distributor analysis. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Good operating system performance depends on the ability of the operating system to effectively manage resources. In the past, heap memory manager was the actual specification, but its performance was affected by the demand fo

We knowRedisThere is no self-implemented memory pool, and nothing else is added to the standard system memory distributor. Therefore, the performance and fragment rate of the system memory distributor may affect Redis performance. In Redis's zmalloc. c source code, we can see the following code: 48 /* Explicitly override malloc/free etc when using tcmalloc. */ 49 #if defined(USE_TCMALLOC) 50 #define malloc

Set active register, as its name implies, is to set an interrupt to active state, and clear active register is to clear the active state. here we need to explain some concepts of the interrupt state: Active: If the processor is processing the interrupt processing function at this time, we can say that the interrupt is active at this time; Pending status: if an interrupt is generated but not processed by the processor, we can say that the interrupt is in pending status; Inactive status: if

this register relative to Distributor is 0x300-0x37c . The calculation method is:For interrupt ID m , when DIV and MOD is the integer division and modulo operations:the corresponding Gicd_isactivern number, N , is given by N = m DIVThe offset of the required Gicd_isactivern is (0x300+ ()The bit number of the required set-active bit in this register is mMOD.For the clear active register, write 1 is valid. Write 0 is invalid. The read-out value represe

The following requirements:20% probability to execute method A,1% probability to execute method B,29% probability to execute method C,50% probability to execute the method D If you use a sentence such as if random number to judge, it may be written in chaos, I wrote a random distributor, you can standardize the operation. The following code is used for this distributor: Copy Code code as follows:

Memcached source code analysis ----- slab Memory distributor, memcached ----- slab Reprinted please indicate the source: http://blog.csdn.net/luotuo44/article/details/42737181 Tip: This article uses some global variables that can be set when memcached is started. For the meanings of these global variables, refer to memcached startup parameters. For these global variables, take their default values directly as described in "how to read memcached sou

optimization when loading tables. As you can imagine, in a large game, there are many tables, rows, and cells, and the number of times allocated when reading tables to the memory is as high as that of the ox. The advantage is that once these configuration files are read to the memory, they do not need to be destroyed, because they may be used at any time during the game. Therefore, it is appropriate to use a simple memory distributor that cannot sepa

This set of registers is mainly used to set the interrupt priority. Each register can set four interrupt priorities, each of which corresponds to eight bits, the maximum value of each interrupt priority is 255, and the minimum value is 0. The smaller the value, the higher the interrupt priority. The offset range of the register relative to the distributor base address is 0x400-0x7f8; The number of registers in this group is determined by the value o

The distribution server or distribution database cannot be found for the local server. The distributor may not be installed, or the local server may not be configured as the publisher on the distributor. 2. SQL Server cannot disable publishing and distribution on "XXXX. ----

The details are as follows: Distribution is the process of obtaining the request object, extracting the module name, controller name, action name, and optional parameters, instantiating the controller, and calling the action.

, and it takes some time to effectively manage the idle memory. This algorithm usually has a high memory usage efficiency (allocating the required memory), but it takes more time to manage the heap. Another method is calledBuddy Memory AllocationIs a faster memory allocation technology, which divides the memory into two power-to-power partitions and uses the best-fit method to allocate memory requests. When a user releases the memory, the user checks the buddy block to check whether the adjacent
