An in-depth understanding of SP, LR, and PC in-depth understanding of the three registers of arm is of great benefit to both programming and porting of the operating system. 1. Stack pointer R13 (SP): Each anomaly pattern has its own independent R13, which usually points to the stack dedicated to the exception mode, i.e. five exception modes, non-exception modes (user mode and system mode), each with separate stacks, indexed by different stack pointer

Article Title: LR monitoring Linux system resource 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. Average load: Average number of processes simultaneously in Ready state during the last minute Average number of processes in the "ready" status at the same time in the last minute Collision rate Collisions p

These days I have compiled some syntax analyzers that can analyze statements that comply with SLR, LR, and lalr specifications. All classes are placed in the syntexparse package. The algorithm comes from longshu. Below are some usage instructions. The symbol class indicates the Terminator and non-terminator in the grammar. The first parameter of the constructor is the symbolic name and the type is string. The second parameter indicates whether the sym

Recently, when doing performance test analysis of LR results, the problem of different response time values of each transaction in summary and average transaction response time was also encountered. Make a note here.If you set the thinking time in the transaction, you need to be aware of the filter thinking time.Set whether the method is included in the View->summary filter, whether there is a filter that contains the think time (the last item in LR11

detailedThe first buffer time test results analysis process, often encountered the first buffer time firstbuffertime, and found that most of the system response time is also wasted here, and then to research and development to explain this problem, and can not take firstbuffertime directly to research and Development said, Take time to tidy up, hope to be useful to everyoneThe following information is from the LR help manual:Definition: The first buff

An in-depth understanding of the three registers of ARM is of great benefit to programming and porting the operating system. 1. Stack pointer R13 (SP): Each exception mode has its own R13, which usually points to the stack dedicated to the exception mode, that is to say, the five exception modes, non-exception modes (user mode and system mode) all have their own independent stacks and are indexed using different stack pointers. In this way, when the arm enters the abnormal mode,ProgramThe gene

a preface In the performance test framework development, you need to process the completed test report of the scene, summarize the performance metrics data that you are following in the report, and then write the report and send the relevant person a message. So, one of the steps is how to capture the data from the test report (e.g.,TPS, Response time, number of concurrent users, etc.). Two problem analysiswhen LR generates a test report, it saves the

Final effect Original 1, Lightroom (hereinafter referred to as LR) color palette. This LR a lot of people like to call him a digital darkroom, suitable for batch simple adjustment of color and light and shadow. As with the CS from the ACR is the same as the development of adobe, the basic function is similar. So the following LR palette

Other effects can be added as needed. Original Final effect 1, Lightroom (hereinafter referred to as LR) color palette. This LR a lot of peop

Today we will talk about group and user problems in LR. I saw a post a few days ago. Q: What is the difference between 10 users in a group and 10 users in each group? Let's take a look at the official help of LR: MultithreadingVusers support multithread environments. the primary advantage of a Multithread environment is the ability to run more vusers per load generator. only threadsafe protocols shocould b

longer to avoid this situation. 4. Previously, LoadRunner monitoring was successful, but no information can be monitored again? A: The rstatd daemon is not enabled because the system restarts. You can manually re-open the rstatd and run the "rpc. rstatd" command. You can also run the "rpcinfo-p" command to check whether the rstatd daemon has been started in the current system. 5. How can I use LR to monitor Linux windows? This is a problem with the t

A problem that has been plagued for a long time has finally been solved. Although the method is simple enough to ignore, the process is tortuous and worth remembering. Problems found: When LR was used for stability tests at the end of last year, the system automatically crashed and exited after a period of time. Check the log and find the error "error -- Memory violation: exception access_violation received". I searched the internet for a majority o

LR While the recording program is running, Vugen (script builder) automatically generates a script that contains the values that are actually used during the recording, and if you attempt to perform a script activity (such as queries, commits, etc.) using different values in the recorded script, you must replace the recorded value with the parameter value. This process is called parameterization.The following is a parameterized process:The parameteriz

The relationship between the number of iterations of the script in LoadRunner and the run time of the scene The Vugen and controller iterations of LR are as follows: when the duration of the scene is run to end, the number of iterations set in Vugen when the duration of the scene is "specific minutes", ignoring the number of iterations in the Vugen, the action of the footstep repeats the iteration until the end of the time, by exiting the policy, perf
