Install CentOS prerequisites for EMOD source code#

This section describes the software packages or utilities must be installed on computers running CentOS 7.1 to build the Eradication binary for Linux from source code and run regression tests.

If additional software is needed for the prerequisite software due to your specific environment, the installer for the prerequisite software should provide instructions. For example, if Microsoft MPI v10 requires additional Visual C++ redistributable packages, the installer will display that information.

Note

IDM does not provide support or guarantees for any third-party software, even software that we recommend you install. Send feedback if you encounter any issues, but any support must come from the makers of those software packages and their user communities.

Install prerequisites for running simulations#

The following software packages are required to run simulations using the Eradication binary for Linux. You can skip this section you already installed the pre-built Eradication.exe using the instructions in EMOD installation for generic, Install EMOD for HIV, or Install EMOD for malaria.

Before you begin, you must have the following:

  • sudo privileges to install packages

  • 15 GB free in your home directory (if you install the EMOD source code and input files)

  • An Internet connection

  1. On GitHub on the EMOD releases page, download and run the PrepareLinuxEnvironment.sh script.

    Respond to the prompts for information while the script is running.

    1. Set the EMOD_ROOT environment variable to the path to the EMOD source path:

      EMOD_ROOT=~/IDM/EMOD

    2. Include Scripts and . in the path:

      export PATH=$PATH:.:$EMOD_ROOT/Scripts

    3. If you want to run simulations in the same session that you updated EMOD_ROOT and the Scripts path, reload the .bashrc file using source .bashrc.

Install prerequisites for compiling from source code#

For CentOS 7.1, all prerequisites for building the Eradication binary for Linux are installed by the setup script described above. However, if you originally installed EMOD without including the source code and input files that are optional for running simulations using a pre-built Eradication binary for Linux, rerun the script and install those.

Install prerequisites for running regression tests#

The setup script includes most plotting software required for running regression tests, where graphs of model output are created both before and after source code changes are made to see if those changes created a discrepancy in the regression test output. For more information, see Regression testing. You may want to install R or MATLAB, but both are optional.

We recommended that you download some of the NumPy Python package from http://www.lfd.uci.edu/~gohlke/pythonlibs, a page compiled by Christoph Gohlke, University of California, Irvine. The libraries there include linear algebra packages that are not included by default with the standard Windows packages. They are compiled Windows binaries, including the 64-bit versions required by EMOD. The naming convention used lists the Python version after “cp”, for example “cp39-cp39m”, and the Windows bit version after “win”, for example “win_amd64”.

(Optional) R#

The IDM test team uses R 4.1.2 (64-bit) for regression testing, but it is considered optional.

R is a free software environment for statistical computing and graphics.
