Environment Variables

Environment variables are key-value pairs that can affect the way running processes will behave on a computer. If you are running in a HPC environment using Slurm workload manager, then you can set these in the job description file.

Setting Environment Variables

GROGUPY_ARCHITECTURE: This variable sets the architecture for the grogupy project. By default, the architecture is set to CPU. To change it to GPU, you can set the GROGUPY_ARCHITECTURE environment variable:
```
export GROGUPY_ARCHITECTURE=GPU
```
GROGUPY_TQDM: With this variable you can request tqdm for a nice progress bar. It can be set to true of false.
```
export GROGUPY_TQDM=TRUE
```
CUDA and CuPy: If you have a problem with GPU acceleration, then you might have to set the appropriate variables to link CuPy with CUDA. For more information see Fixing problems with GPU.
