Question 1

How to set up Concurr servers on multiple machines?

Accepted Answer

Install Concurr via Cargo on each server, run the server binary, and configure client connections. The README lacks detailed deployment guides, so you may need to handle network and dependency setup manually.

Question 2

Concurr or GNU Parallel for batch processing on a single server?

Accepted Answer

Use GNU Parallel for single-machine tasks as it's simpler and more established. Concurr introduces unnecessary client-server overhead unless you need distributed execution across multiple systems.

Question 3

Does Concurr work with Bash scripts?

Accepted Answer

Concurr uses the Ion shell for command execution, so Bash scripts may require adaptation or shell invocation. Ensure compatibility by testing commands within Ion's context.

Question 4

How to handle job failures in Concurr?

Accepted Answer

Concurr returns exit status and error output, but the README doesn't mention automatic retries or failure recovery. You'll need to implement custom error handling on the client side.

Question 5

Is Concurr production-ready for large clusters?

Accepted Answer

It's a Rust-based project with efficient I/O, but the minimal documentation and lack of advanced features like load balancing suggest it's best for smaller or experimental setups.

Question 6

Can Concurr distribute jobs based on server load?

Accepted Answer

No, Concurr uses a static slot-based model per server core without dynamic load balancing. Job distribution is input-driven without adaptive scheduling.
