I can’t find any info on this - is there a minimum memory / cpu requirement for being able to run DL4j / ND4J? I built a simple system which only uses ND4J for vector arithmetic - nothing else. When I run that system on my dev machine (64 gb ram) it runs without an issue. When I try to deploy that on a server w/ 2 GB ram, it gets stuck on startup and seems to get stuck forever. I never see the initial ‘Backend used: CPU, OS: Linux’ messages which ND4J prints on startup. What’s the minimum spec I’d need on the server? ---

This is subject to your workload size and how you’re running dl4j. Models can be anything from megabytes to gigabytes. It’s hard to tell what you are trying to do. I would recommend learning a bit about application profiling: > **[A Guide to Java Profilers | Baeldung](https://www.baeldung.com/java-profilers)** > > A quick overview of four popular Java profilers and how they can help you find areas in your code that could benefit from optimization. There really isn’t a simple answer for this. It depends how you’re running dl4j, eg is it an application server, a standalone uber jar? If you want us to be able to answer any question like this, we’d need to know more about the specifics of your setup. From a simple standpoint, I wouldn’t try to deploy any server with just 2g of ram. Generally I would recommend deploying on at least something resembling the specs of a cheap laptop if you want to deploy anything for machine learning. You don’t need a 64 gb server, but a mid size machine at least is recommended if possible. ---

OK, this was due to an application issue. DL4J is running fine on 2g ram. No models loaded, only linear algebra operations being done 🙂
