# How To Install GAMS
|
|
|
|
## Download the proper GAMS version
|
|
|
|
Download the proper GAMS version from https://www.gams.com/latest/ (notice that older versions are found in the `Previous Distributions` box).
|
|
Notice that the **GNU/Linux Systems** version is required for HPC systems.
|
|
|
|
## Manual installation of GAMS
|
|
|
|
GAMS is shipped through an executable file, which will expand all files into a single directory.
|
|
|
|
1. Create a directory for the new version. Example for version 42.3.0:
|
|
```bash
|
|
mkdir -p /opt/psi/Tools/GAMS/42.3.0
|
|
```
|
|
2. Copy the executable to the new created directory
|
|
```bash
|
|
mv linux_x64_64_sfx.exe /opt/psi/Tools/GAMS/42.3.0/
|
|
```
|
|
3. Change permissions of the executable accordingly
|
|
```bash
|
|
chmod +x /opt/psi/Tools/GAMS/42.3.0/linux_x64_64_sfx.exe
|
|
```
|
|
4. Execute it to install the software
|
|
```bash
|
|
cd /opt/psi/Tools/GAMS/42.3.0
|
|
./linux_x64_64_sfx.exe
|
|
```
|
|
5. The created subdirectory is created with the pattern: `gams${v_MAJOR}.${V_MINOR}_linux_x64_64_sfx`. Examples:
|
|
```bash
|
|
/opt/psi/Tools/GAMS/31.1.1/gams31.1_linux_x64_64_sfx
|
|
/opt/psi/Tools/GAMS/42.3.0/gams42.3_linux_x64_64_sfx
|
|
```
|
|
6. Add the proper version in the variants file and run the build file
|
|
```bash
|
|
cd ~/buildblocks/Tools/GAMS
|
|
echo "GAMS/42.3.0 unstable" >> files/variants.rhel7
|
|
./build 42.3.0
|
|
```
