kandi X-RAY | samples Summary
EventStoreDB is an industrial-strength database technology used as the central data store for event-sourced systems. It is available open-source to run locally on most platforms or as SaaS through Event Store Cloud. This repository provides samples demonstrating the functionalities of EventStoreDB and the client SDKs of EventStore and practical usage.

QUESTION
I run sample JHM benchmark which suppose to show dead code elimination. Code is rewritten for conciseness from jhm github sample.
...ANSWER
Answered 2022-Feb-09 at 17:17Those samples depend on JDK internals.
Looks like since JDK 9 and JDK-8152907, Math.log
is no longer intrinsified into C2 intermediate representation. Instead, a direct call to a quick LIBM-backed stub is made. This is usually faster for the code that actually uses the result. Notice how measureCorrect
is faster in JDK 17 output in your case.
But for JMH samples, it limits the the compiler optimizations around the Math.log
, and dead code / folding samples do not work properly. The fix it to make samples that do not rely on JDK internals without a good reason, and instead use a custom written payload.
This is being done in JMH here:

After a recommendation in Android Studio to upgrade Android Gradle Plugin from 7.0.0 to 7.0.2 the Upgrade Assistant notifies that Cannot find AGP version in build files, and therefore I am not able to do the upgrade.

Originally this is a problem coming up in mathematica.SE, but since multiple programming languages have involved in the discussion, I think it's better to rephrase it a bit and post it here.
In short, michalkvasnicka found that in the following MATLAB sample

should be fine, but it looks like the timing is being skewed by memory pre-allocation.
I can reproduce similar timings to your MATLAB example, however
On first run (
clear
workspace)- Loop approach takes 2.08 sec
- Vectorised approach takes 1.04 sec
- Vectorisation saves 50% execution time
On second run (workspace not cleared)
- Loop approach takes 2.55 sec
- Vectorised approach takes 0.065 sec
- Vectorisation "saves" 97.5% execution time
My guess would be that since the loop approach explicitly creates a new matrix via zeros
, the memory is reallocated from scratch on every run and you don't see the speed improvement on subsequent runs.
However, when HH
remains in memory and the HH=___
line outputs a matrix of the same size, I suspect MATLAB is doing some clever memory allocation to speed up the operation.
We can prove this theory with the following test:
QUESTION
sh jmeter.sh -n -t filePath.jmx -l outFilePath.jtl -e -o folderPath
...ANSWER
Answered 2021-Sep-23 at 07:18I cannot reproduce your issue using:
openjdk:8-jre-alpine
docker image- JMeter 5.4.1
- Test plan
Test.jmx
from extras folder of JMeter
Demo:
If you cannot reproduce the above behaviour I think you made some changes either to Results File Configuration or to Reporting Configuration or both so you need to inspect all the JMeter Properties which differ from the defaults and restore their values to the original ones.
If you need further support you need to share at least first 2 lines of your outFilePath.jtl results file. Better if possible the full file and all the .properties files from JMeter's "bin" folder.

Answered 2021-Dec-09 at 23:12You end up with the error with precision because some of your penalization is too strong for this model, if you check the results, you get 0 for f1 score when C = 0.001 and C = 0.01
QUESTION
I've installed Windows 10 21H2 on both my desktop (AMD 5950X system with RTX3080) and my laptop (Dell XPS 9560 with i7-7700HQ and GTX1050) following the instructions on https://docs.nvidia.com/cuda/wsl-user-guide/index.html:
- Install CUDA-capable driver in Windows
- Update WSL2 kernel in PowerShell:
wsl --update
- Install CUDA toolkit in Ubuntu 20.04 in WSL2 (Note that you don't install a CUDA driver in WSL2, the instructions explicitly tell that the CUDA driver should not be installed.):
ANSWER
Answered 2021-Nov-18 at 19:20Turns out that Windows 10 Update Assistant incorrectly reported it upgraded my OS to 21H2 on my laptop.
Checking Windows version by running winver
reports that my OS is still 21H1.
Of course CUDA in WSL2 will not work in Windows 10 without 21H2.
After successfully installing 21H2 I can confirm CUDA works with WSL2 even for laptops with Optimus NVIDIA cards.

Install samples
You can use samples like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the samples component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
