Introduction: DB2Conditional processors play an irreplaceable role in stored procedures. In DB2,SQLThe stored procedure can use the DB2 Condition processor (Condition Handler) to processSQL Error(SQLERROR), SQL warning (SQLWARNING), no data (NOT FOUND) three common conditions and your own defined trigger conditions, you can use include EXIT, CONTINUE) three condition processors, including UNDO and UNDO. The following describes the detailed analysis of
Linux has always adhered to the symmetric multi-processing mode, which means that compared with other CPUs, the kernel does not have any bias towards one CPU. However, the multi-processor machine has many different styles, in addition, the implementation of the scheduler varies with the hardware features. We will pay special attention to the following three different types of multi-processor machines:

Process Management-Processor Scheduling
I. Basic concepts of scheduling
1. Job Scheduling
Job Scheduling is also calledMacro or Advanced scheduling. Select a job in the backup status and create a process. Generally, most batch processing systems are equipped with job scheduling. In other systems, Job Scheduling is usually not required. The Job Scheduling frequency is low, usually several minutes.
2. Process Scheduling
Process Scheduling is an operatio
From the very beginning, we know the importance of the compiler. Without this, our code is just a bunch of characters. The steps for the compiler to compile the program
There are four main types of files: preprocessing, compilation, compilation, and linking. Finally, an executable target file is obtained.
What will happen to each of the four steps? I don't know why. Taking GCC as an example, the main work is as follows:
Cpp will be called during preprocessing,
In the compilation phase, cc is ca
After the jafka acceptor receives the client request and establishes a connection, the acceptor sends the socket connection to the processor for processing. Processor processes client requests by following these steps:
1. Read client requests.
2. Call corresponding processing functions for processing based on different client request types.
It is interesting for process
Researchers at the University of California, Davis (University of California, Davis) recently developed a 1000-core processor called "Kilocore", the world's first processor with 1000 cores. Furthermore, these 1000 cores can also be run independently.The Kilocore can execute 1.78 trillion instructions per second, at least in the processor designed by university re

At the same time, he served as a distinguished researcher of the Center for Brain Science, Chinese Academy of Sciences and University post professor. He currently leads his laboratory to develop the Cambrian series of deep learning processors. Prior to this, he engaged in the development of domestic processors for more than 10 years,
This article describes how to implement the session custom session processor in php. you can set the session. save_handler is a user that calls a custom callback function to implement the session custom session processor function, which is very useful, for more information about how to implement a session custom session processor in php, see the following example
With the development of science and technology, dual-core processor is very common in our life, dual-core processor (Dual core Processor) refers to the integration of two computing cores on one processor to improve computing power.
You can open Task Manager, click Performance, you can see the CPU's working status.
MediaTek's products in Taiwan, China, are widely used in mainland mobile phone companies and mobile design companies because of the integration of more multimedia features and lower prices. More because MTK's completion rate is higher, basically in 60, so that mobile phone manufacturers to get mobile phone platform is basically a semi-finished product, as long as a slight processing can be shipped on the shelves. This is the most important reason why many Shanzhai phones use MTK. Below we will t

ARM announces the launch of the latest 32-bit cortex-m processor CORTEX-M7, which delivers up to twice times more computing and digital signal processing than the currently highest-performing ARM architecture microcontroller (MCU) ( DSP) performance. The ARM cortex-m7 processor is designed for high-end embedded applications for next-generation automotive electronics, networking equipment, and smart home an
This article is the second part of the two sections, discussing the obstacles to porting OpenGL games to Google Android. Before you start a game implant project (including differences in OpenGL extensions, floating point support, texture compression formats, and the GLU Library), you should recognize these obstacles. It also describes how to use OpenGL ES to set up an Android development system for the Intel Atom processor and how to obtain the optima
Processor designers always focus on different performance promotion strategies in order to perform as many computations as possible within each clock cycle. Faster frequencies, larger data paths, and different instruction sets improve performance. However, one aspect of performance improvement that is most likely to cause misunderstanding is the impact of hyper-threading on processor performance.
