Lasp is a programming model for synchronization-free computations.
Lasp requires Erlang 19 or greater. Once you have Erlang installed, do the following to install and build Lasp.
$ git clone git@github.com:lasp-lang/lasp.git
$ cd lasp
$ make
You can run a Erlang shell where you can interact with a Lasp node by doing the following:
$ make shell
To run the test suite, which will execute all of the Lasp scenarios, use the following command.
$ make check
