Python functions (on PSC/Bridges, keras jobs are to be run on a GPU, either with the "interact -gpu" command or a SLURM script, and require special "module" and "activate" commands):

• bulgaria.py, a python script that uses matplotlib to create a jpg graphic file.
• bulgaria_interactive.py, a python script that uses matplotlib to plot some data, which is shown interactively on the screen.
• class_example_imdb_instructor.py, a python/keras script that uses the IMDB movie database.
• hello.py, a one-line python script that is to be created on Bridges using the nano editor, and then executed interactively by typing "python hello.py".
• hello_keras.py, a python/keras script that essentially just checks whether keras is available.
• hw9.py, a python script that is to be run interactively on Bridges, by a command like "python hw9.py > hw9.txt". The output from this script should be sent to the instructor as hw9.txt.
• mario.py, a python script that uses matplotlib to create a png image.
• montana.py, a python/keras script that can be run on Bridges, which solves a simple regression problem and creates a png image of the result.

Shell scripts (sent to the PSC/Bridges job scheduler by "sbatch filename.sh"):

• hello_keras_psc.sh, a SLURM script that can submit the hello_keras example to be run on the PSC Bridges system.
• mario_psc.sh, a SLURM script that can submit the mario example to be run on the PSC Bridges system.
• montana_psc.sh, a SLURM script that can submit the montana example to be run on the PSC Bridges system.

Text:

• bulgaria_data.txt, a data file containing pairs of ( year, population ) for Bulgaria.
• hello_keras_psc.txt, printed output from hello_keras.py.
• hw9.txt, printed output from hw9.py.
• mario_psc.txt, printed output from mario.py.
• montana_psc.txt, printed output from montana.py.

Images (can be viewed on PSC/Bridges by "display filename.png"):

• bridges.png, an image of some of the 850 machines that make up Bridges.
• bulgaria.jpg, a simple graph created by bulgaria.py.
• mario.png, a plot created by the mario script.
• montana.png, a plot created by the montana script.
• putty_config.png, a screenshot of the putty configuration.
• putty_ssh.png, a screenshot of the putty ssh configuration.
• winscp_config.png, a screenshot of the WinSCP configuration.
• winscp_interface.png, a screenshot of the WinSCP graphical user interface.
