In the below reproducible code, the custom balTransit() function correctly populates a values transition table using a for-loop, while the custom balTransit_1() function is supposed to do the same using lapply() but it doesn't work. What am I doing wrong in my implementation of lapply()? Run the code and you'll see results of:

balTransit (correct results):

I have access to a large computing cluster with many nodes each of which has >16 cores, running Slurm 20.11.3. I want to run a job in parallel using furrr::future_pmap(). I can parallelize across multiple cores on a single node but I have not been able to figure out the correct syntax to take advantage of cores on multiple nodes. See this related question.

Here is a reproducible example where I made a function that sleeps for 5 seconds and returns the starting time, ending time, and the node name.

I have to call SOAP webservice and serve it. I am using strong-soap library(https://github.com/loopbackio/strong-soap). I get my data in the service and I can see it in console.log() but I can't send this data to my controller to serve it. I have tried using pipe(map()) and I have looked into this following topics (https://www.freecodecamp.org/news/an-express-service-for-parallel-soap-invocation-in-under-25-lines-of-code-b7eac725702e/) but no luck. I either get 'can't subscribe to undefined' or my request is passing without my controller getting the data and serving it.

Here is my controller.ts

I am trying to execute a python script in parallel by using the lines of a file as arguments to a python script. The file is named experiments.txt and might look like this:

I have to switch drivers between the run to 2 different service providers in the same testcase/scenario.

Presently I'm using "env.resources" to set multiple Env details in different files, but "remote.server" in the 2nd env file always takes over.

Eg:

Web Test: BrowserStack | Appium/App Test: ExperiTest

I have referred following post, which talks predominantly about switching drivers but not multiple remote.server/port

According to the below link, we can set up multiple environments, but how can I pass the env details during the run via switchDriver

I am trying to use JMeter Throughput Shaping Timer on a JMeter distributed environment. JMeter master was configured with the JMeter Maven plugin. I have added the required plugins on the pom.xml and JMeter slave nodes. I double-checked my plugin versions on both sides and can confirm those versions are similar.

JMeter master runs with below dependencies list

I am working with the R programming language. I am trying to plot some categorical and continuous data that I am working with, but I am getting an error that tells me that such plots are only possible with "only numeric variables".

I ran into an issue which is basically that Gradle can not find the ParallelSampler class in which I included in my gradle file.

Basically, I am trying to use the plugin(ParallelSampler) developed by blazemeter in my project.

I am not sure why it is happening.
