8.4 Hardware and Software requirements

8.4.1 Requirements for openLCA

  • Windows / macOS / Linux
    • 1 GB RAM (for analysing product systems with 2,500 processes, such as ecoinvent 2)
    • >3 GB RAM (for analysing product systems such as ecoinvent 3)
    • 6 GB RAM (for analysing product systems such as ecoinvent 3.4 or Psilca for social LCA)
    • 500 MB free hard disk space + space for databases (e.g. ecoinvent 3 requires 250MB)

8.4.2 Requirements for the LCA Collaboration Server


Minimum:

CPU: DualCore CPU or better

RAM (Elasticsearch/LCA CS): 2GB/2GB

Disk: HDD (the required disk space depends mostly on the amount of data you want to be able to host; the application itself only requires <100MB) Recommended:

CPU: QuadCore CPU or better

RAM (Elasticsearch/LCA CS): 4GB/8GB

Disk: SSD4

Software requirements:

The LCA Collaboration Server is a web application based on Java Servlet. We recommend the use of Tomcat 8 in combination with Java 8. Most testing has been done under use of this configuration (for both Windows 10 and Ubuntu/Debian Linux).

The LCA Collaboration Server depends on Elasticsearch. Since version 6 it does not support JVM internal local nodes. Therefore, Elasticsearch must be installed and run separately.
