# threads - metered_concurrency

This folder contains an implementation of a metered concurrency task and it
was coded for a contribution to the Rosetta Code website.

For more information see:

	https://rosettacode.org/wiki/Metered_concurrency#Logtalk

When using XVM as the backend, this example must be run from the top-level
interpreter.

Print Logtalk, Prolog backend, and kernel versions (if running as a notebook):

```logtalk
%versions
```

Start by loading the example:

```logtalk
logtalk_load(metered_concurrency(loader)).
```

Run example:

```logtalk
metered_concurrency::run.
```
