QUESTION
For the following Gatling simulation
...ANSWER
Answered 2022-Apr-11 at 17:08Right now we've tested only with primitive values passed into the Gatling session. It may work if you convert the data into a java.util.Map. So maybe your best bet is to write some toMap() function on your data-object. Or if you manage to emit a JSON string, there is a karate.fromString() helper that can be useful.
So please read the docs here and figure out what works: https://github.com/karatelabs/karate/tree/master/karate-gatling#gatling-session
You are most welcome to contribute code to improve the state of things.

QUESTION
My objective is to obtain the ability of parallelizing a code in order to be able to run it on GPU, and the Graal would be to have a software that can run in parallel on any GPU or even CPU (Intel, NVIDIA, AMD, and so...).
From what I understood, the best solution would be to use OpenCL. But shortly after that, I also read about SYCL, that is supposed to simplify the codes that run on GPU.
But is it just that ? Isn't better to use a lower level language in order to be sure that it will be possible to be used in the most hardware possible ?
I know that all the compatibilities are listed on The Khronos Group website, but I am reading everything and its opposite on the Internet (like if a NVIDIA card supports CUDA, then it supports OpenCL, or NVIDIA cards will never work with OpenCL, even though OpenCL is supposed to work with everything)...
This is a new topic to me and there are lots of informations on the Internet... It would be great if someone could give me a simple answer to this question.
...ANSWER
Answered 2022-Feb-12 at 09:08Probably yes.
OpenCL is supported on all AMD/Nvidia/Intel GPUs and on all Intel CPUs since around 2009. For best compatibility with almost any device, use OpenCL 1.2. The nice thing is that the OpenCL Runtime is included in the graphics drivers, so you don't have to install anything extra to work with it or to get it working on another machine.
SYCL on the other hand is newer and not yet established that well. For example, it is not officially supported (yet) on Nvidia GPUs: https://forums.developer.nvidia.com/t/is-sycl-available-on-cuda/37717/7 But there are already SYCL implememtations that are compatible with Nvidia/AMD GPUs, essentially built on top of CUDA or OpenCL 1.2, see here: https://stackoverflow.com/a/63468372/9178992
QUESTION
if I want to build my Quarkus 2.7.3.Final application with GraalVM CE 22.0.0.2 in native mode, I get a build error caused by the PrestoDB JDBC driver.
Also, I get the following exceptions when I make a SQL query on PrestoDB 0.270 and it only occurs if I run the application in native mode.
With the Quarkus JVM mode, the query just works fine.
Docker build image: quay.io/quarkus/ubi-quarkus-native-image:22.0.0-java17
I'm using JDBC driver com.facebook.presto:presto-jdbc:0.270 with a custom agroal connection and driver class com.facebook.presto.jdbc.PrestoDriver

QUESTION
Trying to solve an issue with Proxy classes + native mode with Quarkus, and hitting a roadblock.
The docs outlining the tips for solving the issue don't specify how to add the additional build args with Gradle....
Reference docs: https://quarkus.io/guides/writing-native-applications-tips#managing-proxy-classes
The odd point being I found the following issue outlining an addition for Gradle, but no mention on the docs, and the command the issue recommends doesn't seem to work either (--additional-build-args)

How does one pass the args to Graal?

QUESTION
Is there any test suite/list of all possible errors defined by the ECMAScript spec? I am currently writing a JavaScript Runtime and I wanted to have fancy errors so I need to parse them from the engine and handle accordingly.
The engine is Graal.jS, if that matters.
Regards - Yush.
...ANSWER
Answered 2022-Jan-20 at 17:55Is there any list of all possible errors defined by the ECMAScript spec?
Sure, the list of possible error types is in the ECMAScript spec itself. But it seems you're only interested in SyntaxError specifically.
Is there any list of all possible syntax errors in JavaScript?
No. The ECMAScript specification does not mandate any specific error messages for syntax errors. Any engine is allowed to bring their own, and is also allowed to implement syntax extensions.
The engine is Graal.jS, if that matters.
Yes, it does matter. Graal.js does implement some syntax extensions. As for the list of possible parser error messages, you probably best look into the source code of the parser itself.
Here's a list of errors that I extracted (dirtily with the regex /(?<=throw error\().*?(?=,[^,]*\);)/g) from the mentioned file:
QUESTION
I want to use a Java object new Train() as an argument to pass into a JavaScript function, here is the Java code
ANSWER
Answered 2022-Jan-13 at 16:45GraalJS (and GraalVM in general) has tight security/access controls by default. GraalJS is not exposing getSpeed() (or any other field or method) on the Train instance to JavaScript.
You can open up access to all host fields/methods with a configuration setting:

I have a JavaFX-based desktop app, for which I create native images via GraalVM/GluonFX. To retrieve the version of the app during runtime, I previously – when there was only a fat JAR of the app – used Package#getImplementationVersion(). However, this returns null.

due to Nashorn being discontinued we are currently trying to change our (still Java 8) application (very big monolith) from Nashorn to GraalVM. Due to the application being used as library in multiple projects, instead of using the whole GraalVM runtime we decided to just adding the necessary jars to the class path (which seem to work so far).

Install graal
You can use graal 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 graal 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 .
