HS-4. Virtual Box image for reproducibility of SUMMA modeling using Local Approach-1, 2, 3, 4, and 5

This HydroShare resource provides five local approaches using Virtual Box image.
First, users need to install Virtual Box (https://www.virtualbox.org/wiki/Downloads) at first.
Then import this \"research.ova\" to create a SUMMA and pySUMMA computational environment in Virtual Box.

After creating \"research.ova\" image on Virtual Box, users need to move to the \"/home/hydro/project/Performance_Test\" folder to start SUMMA run.
Then, users can follow the \"instruction.txt\" in each approach foler.
The password of this \"research.ova\" image is \"hydro.\"

This Virtual Box image five local approaches:
- Approach-1 Compiling the core model software
- Approach-2 Containerizing the core model software only with Docker
- Approach-3 Containerizing all software with Docker
- Approach-4 Containerizing all software with Singularity
- Approach-5 Containerizing all software and modeling workflows with Sciunit
