1 PrefaceWhat is Apache Nifi? The Nifi website explains the following: "An easy-to-use, robust and reliable data processing and distribution system". In layman's terms, Apache NiFi is an easy-to-use, powerful, and reliable data processing and distribution system designed to support data routing, transformation, and system mediation logic for highly configurable indicators.To be clearer about what Nifi can articulate, the following is a brief introduction to the Nifi architecture, as shown in.Acc

1.1. Advanced scheduling (long-range scheduling and Job Scheduling)
Function: According to an algorithm, the jobs in the backup queue in the external storage queue are transferred to the memory, and the job is the operation object.
Job: A more extensive concept than a program. It not only contains common programs and data

The first section describes general optimization techniques for vectorization (data parallelization) processing of code.
The second section describes how to add thread-level parallelism to take advantage of al
old processDatastandby memory is the memory that is removed from the process working set (its physical memory) and then into the disk, but the memory can still be recovered.The counter displays only the last observed value; is not an average. Technology: 10% of available memory is generally reserved. The lowest minimum can not be cause: Because IIS uses up to 50% of the available memory for the file cache by default, it retains 10% of available memory (for peak time use). Knowledge Points: phys
DB2 exception processor is still unfamiliar to many new users who have just been familiar with the DB2 database. Next we will introduce the DB2 exception Processor type for you. I hope it will help you.
DB2 exception Processor type (handler-type) has the following types:

Intel Core i5 and i7 can be said to be the most mainstream desktop processor in the market, with a large number of laptops and desktops using these two processors. So, if you want to buy a computer, should consider i5 or i7? Look at the major differences between them.
Hyper-Threading
Hyper-threading means that each processor core can handle two threads rather than one, with better performance
The detail parameters of the processor, features supported features summed up very complex, want to say it may take a long time, but for ordinary consumers do not need to know so many irrelevant technical indicators, for the mass consumer groups as long as you know which performance is good to help the decision to buy this is enough, So today we say that the mobile version of the processor in the notebook,
3rd Chapter CORTEX-A8 Processor Programming
1. Introduction to ARM programming
• In the development of embedded systems, the main programming languages currently used are C and assembler. In many places, such as the initialization of hardware system at boot time, including the setting of CPU state, interrupt enable, the setting of the main frequency, as well as the control parameters and initialization of RAM are used in assembly language. Assembly la
, conditional variables, counting semaphores, mailboxes, and event flags) required by the embedded system ), it also has flexible scheduling policies and interrupt processing mechanisms, so it has good real-time performance. Compared with the eCos operating system in Embedded Linux, ECOs is more suitable for devices that process real-time signals, such as mobile communication and WLAN communication equipment development.The ECOs kernel scheduling mechanism is shown in the following table:
1. Server processor clock speed
The clock speed of the server processor is also called the clock frequency. The unit is MHz, which indicates the computing speed of the CPU. CPU clock speed = frequency X frequency doubling coefficient. Many people think that the clock speed determines the CPU running speed. This is not only one-sided, but also a misunderstanding of the server. So far, there is no definite f
Intel released the Xeon E5-2600/1600 series processor in early March, following the famous Tick-Tock strategy. The generation of Xeon E5-2600 series still follows the SandyBridge architecture adopted by single-channel Xeon E3, but because E5 is a product for dual-channel applications, it is named "SandyBridge-EP ". As Intel's main product, Xeon E5-2600/1600 series processor is mainly to provide better cloud
I will upload my new book, "Write My Own processor" (not yet published), today is the third article. I try four articles a week.MIPS instruction set architecture since the advent of the 80 's. has been upgrading, from the initial MIPS I to MIPS V, to support the expansion module MIPS32, MIPS64 series, and integrated code compression technology microMIPS32, microMIPS64. Each MIPS Isa is a superset of its previous, no matter what omission, just add new
This is an article that has been late for a long time. Article If I did not see the article "esframewok-based client and Client Communication" written by mediar today, I may not remember to write this blog that should have been published very early, it can help esframework researchers/users better use esframework. The mediar friend's article describes how to forward p2pmessage through the server. mediar manually implements a processor. In fact, esfram
The Updater Application Block provides a post-processing architecture that allows developers to create a post-processor after successful upgrade. The post-processor implements the IPostProcessor interface.. Net class, which is used to execute one-time post-installation tasks, such as writing data to the Registry, creating a message queue, or other tasks that cannot be completed by simply copying application
Most processors support at least two modes of execution. Some instructions can only be executed in privileged mode, including reading or altering instructions for control registers such as the program status Word, raw IO instructions, and memory management-related instructions. In addition, a portion of the memory area can be accessed only under privileges.A non-privileged state is often called a user state, because the user program is usually executed in that mode, and the privileged state is c

S3C2440 Processor ArchitectureThe structure of the s3c2440 processor, as shown, is the core unit of the ARM9TDMI processor core, including the 16K instruction cache and 16K data cache, as well as the separate instruction and data MMU unit. The CP15 is a coprocessor (co-processor). Connect to external devices via t
