short as possible Ø no more than 200 rows. IBM research shows that the maintainability and error rate of subroutines with more than 200 rows will increase.5. How to Use subroutine Parameters Follow input-Modify-Output sequence ParametersModify: parameters used for both input and output in a timely manner, such as reference objects If several subprograms use similar parameters to make the order of these parameters consistent. For example, the Append (array Use all parameters Put the status or e

NSLayoutConstraint basics for Automatic Layout of IOS pagesBefore using AutoLayout, you need to know the following two points: 1. You must set translatesAutoresizingMaskIntoConstraints to NO. 2. For viewControl, AutoLayout adaptation is written in [-updateViewConstraints]; for view adaptation, AutoLayout adaptation is written in [-updateConstraints. I. Methods to be explained: 1 /* Create constraints explicitly. Constraints are of the form "view1.attr1 = view2.attr2 *

closure is a function, and its return value depends on the value of declaring one or more variables outside of this function. Consider the following piece of code that uses an anonymous function: Val multiplier = (i:int) => I * 10 Here, the unique variable used in the function body, I * 0, is the I, which is defined as a function of a parameter. Now, let's look at another piece of code: Val multiplier = (i

1. Modify the default Linux I/O scheduling algorithm. the default linux I/O scheduling algorithm is cfq and needs to be modified to dealine. If it is an SSD or PCIe-SSD device, you need to change it to noop. You can use the following two methods to modify it. 1. dynamic online modification and reboot failure. Echo "deadline" sysblocksdaqueueschedulertips: The sda representative here 1. Modify the default Linux I/O scheduling algorithm. the default lin

, reduce the consumption of disk IONetwork cardAt present, the Internet company Dell's server should be used the most, and in the absence of special needs of users, the configuration of the network card is usually Broadcom bcm57xx, this network card is cheaper all in the processing of small packets, bandwidth utilization is not high, and the traffic will appear a large number of packet loss. The Intel x350i QP Network card is recommended on Tengine/nginx machines, and more performance control ca

How to enumerate Pciecapability1. Organizational structure of the Capabilityaccording to The layout of the PCIe SPEC 3.0, pciecapability, is as follows: the Offset0x00~0xff falls between the PCIE capability structure Corresponds to the PCI configuration space, and falls between the offset0x100~0x1000 and belongs to the EXTENDEDPCIE capability, which corresponds to the pcieextended Configure the space. 2.

2011 in 5.1% to 15% so far, becoming among the many NANDFlash application products, one of the most explosive growth categories.Trend 5: PC-SSD interface will be based on SATA3.0, the future is expected to upgrade to a higher speed PCIe-Like interfaceIn 2011 PC-SSD (PC solid state drive) used by the standard transmission interface is still dominated by SATA2.0, 2012 with the IvyBridge processor market, SATA3.0 will gradually become the mainstream int

Fault Code Description quick query table debug code 1. Special codes "00" and "FF" and other start codes may occur in three situations: ① If "00" or "FF" is displayed after a series of other codes, the motherboard is OK. ② If no error is set in CMOS, the non-serious fault will not affect the BIOS self-check, and "00" or "FF" will eventually occur ". ③ The "00", "FF", or other starting Code does not run when the server is started and does not change. 2. This table is sorted by code value from sma

Flashtec NVRAM accelerator achieves 15 million iops at a latency of several microseconds Enterprisetech PMC has recently provided a brand new product for very large-scale data center operators and enterprise-level storage vendors to help them build more avant-garde storage infrastructure. PMC was founded thirty years ago. As an industry-recognized semiconductor company, it previously specializes in communication equipment and has entered the enterprise storage market in seven years. The company

ATI has recently announced their x700 PCIe graphics card and a New Catalyst Driver in Cyprus. At the same time, Ati's product manager Terry makedon also revealed that they are ready to officially launch support for the Linux driver in the coming weeks. He said that Ati's investment in this area will be proportional to linux4% market share. Makedon also said that ATI has created a new Linux driver development team. The new team contains many new de

full speed, and the CPU cache must be consistent. GPU accesses pinned memory through PCIe, and cache consistency must also be maintained. Device visible host memory: As part of the pinned memory, you do not need to maintain the CPU cache consistency during GPU access, which can speed up GPU access. However, because there is no cache consistency, CPU read of these memory slows down, because combined write can be used (that is, write operations are per

parameter contains the user's buffer information... if you execute an asynchronous read call and send a read message, it will be returned directly. In another help thread, the Recv will be returned and the main thread will be notified... To illustrate the problem, the simplest example is to use the Netlink mechanism to replace the system call kill for sending signals. The source code of the kernel module is as follows:# Include The user code is as follows:# Include Netlink is widely used. You
