According to my testing, if you:

1. Update to CUDA 11.1 Update 1 (so that nvcc --version reports 11.1.105)

2. Change the lddx parameter to be equal to n:

The JSON you provide in your question is not valid... This seems to be just a fragment of a larger JSON. As your data starts with a [ you have to think of it as an array, so the simple json path '$.serviceTierCounts.cnt' won't work probably...

Try this, I've added the opening { and the closing brackets at the end:

The slack statement in catch block has wrong syntax for string concatenation, ${environment} should either be wrapped in double quotes (") or ${} removed to fix the issue:

There are a few issues with the code. Let's deal with them before answering your question. First, you set a threshold of 0.5 for making decisions (Yhat_train = (train_predict >= 0.5);) while all points of your net prediction are above 0.5. This means you only get zeros in your confusion matrices. You can plot the scores to choose a better threshold:

Or Redis can be enhanced by clustering or something else?

Redis can be clustered, in different ways:

• "regular" redis can be replicated to secondary read-only nodes, on the same machine or different machines; you can then send "read" traffic to some of the replicas
• redis "cluster" exists, which allows you to split (shard) the keyspace over multiple primaries, sending appropriate requests to each node
• redis "cluster" can also make use of readonly replicas of the sharded nodes

Whether that is appropriate or useful is contextual and needs local knowledge and testing.

Achieving this, is Considering L1 cache for a Redis cache a good solution?

Yes, it is a good solution. A request you don't make is much faster (and has much less impact on the impact) than a request you do make. There are tools for helping with cache invalidation, including using the pub/sub API for invalidations. Redis vNext is also looking into additional knowledge APIs specifically for this kind of L1 scenario.

why do you expect 2 generated jtl files since you don’t have any listener.

In this case in non gui mode, jmeter would generate only 1 file, this is what the jmeter-maven-plugin does.

by the way, you’re using an old version 2.1.0 of the plugin, last one is 2.7.0.

The following code compiles without errors:

src/test/scala/package_name/PerformanceTest.scala

Two options (certainly not the only ones) demonstrated with some sample data:

For anyone who is facing the same issue. Here is the solution and how I found it.

Firtly the issue was very simple. In my test plan(jmx) I was using a csv file as 'CSV Data Set Config'. I had put something like this

inputFiles\materialstamm.csv

this was woking fine on my local machine because, I was running on windows. And It didn't work on Jenkins because it was a Unix machine. After I changed this to

inputFiles/materialstamm.csv

My jenkins build started running correctly.

Now coming to the point of finding out the issue. This was very hard because, Jmeter didn't report anything in the build process. Even when I enabled maven debug.

Since It could not load my dataset(through csv file) it was just skipping through this and assuming no data and Ended up with Success status for the build but without any report/result.

The trick was to look for Jmeter log files. Jmeter generated log files under ..../workspace/target/jmeter/logs/testplanname.log.

But I did not had console access to jenkins machine and also I didn't see workspace folder by default on Jenkins UI. This answer helped me to get workspace folder. When I checked the log there, it was clearly visible because jmeter threw an exception saying it could not find the csv file.
