SCALAble SimulaTION - ScalaTion

Welcome to ScalaTion, the Scala-based system for Simulation, Optimization and Analytics.

This system, coded in Scala, supports multi-paradigm simulation modeling including 'tableau', 'event', 'process', 'dynamics', 'dynamics_pde', 'activity' and 'state' oriented models.

Scala is a modern object-oriented, functional programming language that is well-suited for developing simulation engines. It is in the Java family of languages and can call Java code. The inclusion of advanced and functional programming capabilities, makes the code much more concise than Java. ScalaTion also supports optimization and analytics as they nowadays go hand-in-hand with simulation modeling. Some of the algorithms come in both sequential and parallel versions.

The ScalaTion 1.3 version defines multiple .par subpackages that contain parallel versions of sequential algorithms. Future directions include completing the 'scala3d' and 'physics' packages.

As of version 1.3, ScalaTion consists of three subprojects: scalation_mathstat, scalation_modeling and sclation_models.

Installation Instructions

1. Download one of the following two files

2. Untar or unzip the file

$ tar xvfz scalation_1.3.tar.gz 
 OR 

$ unzip scalation_1.3.zip

3. To compile code or run apps, enter sbt and type compile, run-main or exit

$ cd scalation_1.3 

$ cd scalation_models 

$ sbt 

> compile 

> run-main apps.process.Bank 

> run-main scalation.analytics.RegressionTest 

> exit

ScalaTion 1.3 is set up to use the Simple Build Tool sbt.

ScalaTion 1.3 uses the following build specification files build.sbt, build.sbt and build.sbt. Source packages are in the src/main/scala directory, class files are in the target/scala-2.12/classes directory, and documentation files are in the target/scala-2.12/api directory. Data file input, output or analytics are stored in subdirectories of data, while database files are stored in store.

To develop using an IDE:

1. Download Scala IDE for Eclipse
2. Extract the downloaded .zip/.tar.gz file
3. Start eclipse by running the eclipse command or clicking eclipse application from the file manager
4. Create and run HelloWorld.scala, see tutorial

For more information about the source code, see src/README_src.hmtl.
