kandi X-RAY | perftest Summary
A simple GPU shader memory operation performance test tool. Current implementation is DirectX 11.0 based. The purpose of this application is not to benchmark different brand GPUs against each other. Its purpose is to help rendering programmers to choose right types of resources when optimizing their compute shader performance. This application is designed to measure peak data load performance from L1 caches. I tried to avoid known hardware bottlenecks. If you notice something wrong or suspicious in the shader workload, please inform me immediately and I will fix it. If my shaders are affected by some hardware bottlenecks, I am glad to hear about it and write more test cases to show the best performance. The goal is that developers gain better understanding of various GPU hardware on the market and gain insight to optimize code for them.

QUESTION
I have one scenario where I am working on the IIS Website Configurations for URL Routing. I have added the website and Import the required Certificates on the server.
My scenario is (I have multiple website URLs and two SSL Certs - as below):
qatest1.abc.com
qatest2.abc.com
qatest3.abc.com
Above 3 URLs need to be configured on one SSL Certificate - which is QA Certificate.
Another URL is:
perftest.abc.com
And for this URL there is a separate certificate as PERF (performance) certificate.
This is how the Task is given to me to configure the IIS Settings on MS IIS 10.
Now the Issues which I am facing is:
- Not able to configure all the URLs configuration on the same IIS, as per the task given to me I am supposed to configure them all on the same IIS.
- Getting a strange message (image attached) and it won't allow me to configure all my above website URLs on the same machine, on the same IIS.
- Also trying to read about SNI (But Not sure about how to make use of SNI in this case).
Need help from IIS Experts who can support me on this activity to complete.
...ANSWER
Answered 2021-Mar-15 at 21:07#1 - its possible via CLI commands (appcmd & netsh) or scripting (PowerShell) and programming (c#) but not with the IIS Manager GUI afaik.
#2 - (see #1). IIS Manager is stupid and will overwrite existing bindings with the last certificate selected. You end up with bindings attached to the wrong certificate if you click Yes. This is a limitation of IIS Manager GUI not IIS.
#3 - You want SNI turned on. It means you can have multiple certificates associated with the same IP address. Without SNI you would need 1 IP address per certificate
These 2 links will give you an idea how to use appcmd and netsh - this is the quickest/easiest way to create your desired configuration.
If you know PowerShell("POSH") you can use the IISAdministration PowerShell cmdlet New-IISSiteBinding to create bindings and associate with a certificates thumbprint (though netsh is still useful for debugging and fixing issues).
Either approach your really configuring 2 things - IIS' bindings and Windows/SChannel/HTTPS.sys (the operating system component actually responsible for the 'S' in 'HTTPS'). Sometimes they get out of sync and the easiest fix is to delete and re-create the bindings (after clicking yes to "At least one other site is using the same HTTPS binding..." for example).
Few tips:
- Once you start using this configuration IIS Manager or Windows Update/software installs will probably break your bindings at some point. Write a script that can remove and re-create all your bindings for port 443(only!) so you can easily fix future issues.
- If you use netsh - its very fussy about the syntax. Order and spacing of parameters are important when using command
netsh http add sslcert. - While your testing
netsh http show sslcertandnetsh http delete sslcertare very useful to try different configurations (this wont delete the cert, just the binding) - Cert needs to be in the Machine certificate store and make a note of the path. When using POSH or netsh always specify both certificate thumbprint and the store\path where the cert was installed.
- If you need a default HTTPS binding on the IIS Site (eg load balancer healthchecks etc) add it before any named HTTPS bindings.
Final aside - if your domains are all 1 level under abc.com getting a wildcard certificate would save you a lot of bother. a single *.abc.com certificate would cover all your domains and you can avoid this limitation entirely.
Good luck!

I am new to using BigQuery. I tried to select my trial project vertical-idea-303617 and run a query against it. But the browser keeps complaining about permissions related to erudite-buckeye-3032181. I don't know what that erudite-buckeye-3032181 project is and I do not have it selected. Why am I still getting errors? See this image here:

We are running jmx through Tauras using 2 containers in Kubernetes. We are seeing only 50 users in results instead of 100(50*2 containers). Can anyone please through some light if we are missing something here. We get two jtl and checking them individual or combined the total users are same 50 only. Is it related to same Thread name being generated and logged in jtl file or something else.
Here is the yml details: ...ANSWER
Answered 2020-Dec-22 at 06:44Your YAML is very nice but it doesn't tell anything about how do you launch JMeter or what these shell scripts you invoke are doing.
If you just kick off 2 separate JMeter instances by means of k8s - JMeter will look at the number of active threads from the .jtl file and given the Sampler/Transaction names are the same JMeter "thinks" that the tests were executed on one engine.
The workaround is to add i.e. machineName() or __machineIP() function to sampler/transaction labels, this way JMeter will distinguish the results coming from different instances and you will see real number of active threads.
The solution would be running your JMeter test in Distributed Mode so master will run in one pod, slaves in their own pods and the master will be responsible for transferring .jmx script to the slaves and collecting results from them
QUESTION
I'm running a CI pipeline in Azure DevOps with a Maven build step called "Download provided dependency JARs".
This step was working before, however it's suddenly giving me this error:
...ANSWER
Answered 2020-Nov-13 at 04:37It looks you ran your pipeline on self-hosted agent. Or you configured the maven to retrieve the dependencies from the local repository(in mvnsettings.xml, or .m2/settings.xml ). If you ran your pipeline on self-hosted agent. You can check if the local repo /testartifacts/m2repository exists.
If you run your pipeline on cloud agents, you need to find which setting files configured the the local repo, And remove the localRepository.
Then you might need to use Maven Authenticate task to provides credentials for Azure Artifacts feeds and external Maven repositories.
Add Maven Authenticate task at the top of your pipeline. And select your azure maven feed from the Feeds dropdown list
This task will store the credentials on a temp settings.xml file(with feed name as the server id, see below) on the agent, which will be used to authenticate the maven repository in the following maven task.
Noted: The repository id you specified in your pom.xml file(ie. see below highlighted) should be the same with the name of your azure artifacts maven feed. Or it will still fail to authenticate the feed in the follow maven task. for the server id in the temp settings.xml file created above is the feed name.

I'm using an extend template and i want to use another template in this just for parameters. But i'm not able to and i'm not sure if the syntax is wrong. getting this error : /templatetest.yml (Line: 8, Col: 1): Unexpected value 'template'
...ANSWER
Answered 2020-Jul-03 at 12:01This is what you are looking for, these docs explain how to use parameters when extending from templates.
In short it means you define all steps in the template yaml file and pass parameter values from the extending yaml file. Keep in mind you can also pass buildsteps as parameter, see here for an example.
See below for a few snippets based on your case.
pipeline-template.yml in repository named TemplateRepo
QUESTION
So, I wanted to create a small game for cross platform, but then I ended up in devices that don't support JIT, such as the IPhone, Windows mobile and Xbox One (game side, not application side).
Since the game had to generate some "basic" code out of text files with scripts in them, like formulas, assignments, call functions, modify/store values in a dictionary per object (sort of like a hybrid interactive fiction game), it wasn't really possible to do with AOT compilation.
After some thinking, I came up with a way around it, store collection of functions and what not, to "emulate" normal code. if this way was alot slower than twice as the compiled code, then I would consider dropping devices that couldn't run JIT compiled code.
I was expecting the compiled code in visual studio to be the fasted, and the Linq.Expressions to be about max 10% slower.
The hack of storing the functions and calling them for each and almost everything, I was expecting to be quite alot slower than compiled code, but.. Too my surprise, it is faster???
Note:
This project is primarily about learning and personal interests in my free time.
The end product is just a bonus, being able to sell or make it open source.
Here is a test example of what I'm doing, and "trying" to model how the code would be used, where there are multiple "scripts" that have different functions and parameters, that operate on the TestObject.
Interesting parts of the code are:
- The constructor of the classes that derive from PerfTest.
- The Perform(TestObject obj) functions that they override.
This was compiled with Visual Studio 2017
.Net Framework 4.7.2
In release mode.
Optimizations turned on.
Platform target = x86 (haven't tested on ARM yet)
Tested the program with visual studio, and standalone, didn't make any noticeable difference in performance.

Big fan of cygwin, having trouble starting jmeter (which is a Java program) from within Cygwin.
I can get it to work just fine, but java doesn't seem very fond of having "/cygwin" in the path to the JAR file. So, I can just pass in the path to the JAR file using a relative path, but that's pretty inconvenient as I move around the file system. Here's a sample to illustrate my issue:
