Big Data course on Beocat

The Pittsburgh Supercomputing Center hosts 2-day remote Big Data workshops several times each year. The information provided here will allow individual users to go through the videos at their own pace and perform the exercises on our local Beocat supercomputer. Each exercise will have data and results tailored to each individual to allow instructors to measure the progress of students assigned to take this course interactively.

Use the Agenda website below to access the slides starting with the Welcome slides that don't have an associated video. The '>' sign at the start of lines below represents the command line prompt on Beocat, and '>>>' represents the prompt you'll get when you start pyspark or python.

Agenda: https://www.psc.edu/hpc-workshop-series/big-data

Videos: https://www.youtube.com/watch?v=NpapUmGHXyw&list=PLdkRteUOw2X-YKqommnuGWqNfEEUG6P2E

Welcome

ssh into Beocat from your computer and copy the workshop data to your home directory.

 > cp -rp ~daveturner/workshops/bigdata_workshop .
 > cd bigdata_workshop

PDF versions of the slides are available for each section as are directories containing the data for each set of exercises. You can copy the PDF files to your local computer for viewing or click on the web link for each section.

Follow along with the Welcome slides from the Agenda website link or PDF file Big_Data_Welcome.pdf as you listen to the video. Much of this information is specific to the Bridges supercomputer at PSC so just scan over these slides.

Welcome: https://www.psc.edu/images/xsedetraining/BigData/Big_Data_Welcome.pdf

Intro to Big Data

History of Big Data: https://www.psc.edu/images/xsedetraining/BigData/A_Brief_History_of_Big_Data.pdf

Watch the video 'Intro to Big Data - Big Data Video 1' and follow along with the slides (A_Brief_History_of_Big_Data.pdf)

Hadoop

Hadoop slides: https://www.psc.edu/images/xsedetraining/BigData/Hadoop2019.pdf

Watch the video 'Hadoop - Big Data Video 2' (Hadoop2019.pdf) We do not have Hadoop on Beocat so the commands they cover will not work locally

Intro to Spark and Spark sections combined

The link below shows how to load the Spark and Python modules on Beocat, set up the Python virtual environment, and run Spark code interactively or through the Slurm scheduler.

https://support.beocat.ksu.edu/BeocatDocs/index.php/Installed_software#Spark

Watch the video 'Spark - Big Data Video 3' (slides are Intro_To_Spark.pdf)

Pause the video and do the exercises 1-5 around the 43 minute mark. Try these yourself before they cover the answers. You can do demos and exercises interactively by requesting an Elf core or you can submit the job using a script (see ~/bigdata_workshop/Shakespeare/sb.shakespeare as an example).

Request 1 core on an Elf node for interactive use then load the modules

 > srun -J srun -N 1 -n 1 -t 24:00:00 --mem=10G -C elves --pty bash
 
 > module purge
 > module load Spark
 > module load Python
 
 > source ~/.virtualenvs/spark-test/bin/activate
 
 > pyspark
 >>>

Email your solutions to exercises 1-5 to Dan along with a description of how well you did on your own. Also include your solutions to homework assignments 1-3 around the 103 minute mark if you want to impress him. Dave's answers are in ~/bigdata_workshop/Shakespeare/shakespeare.py.

Machine Learning: Recommender System for Spark

If you want to run demos and exercises interactively, request 1 core on an Elf node for interactive use then load the modules and activate your Python virtual environment.

 > srun -J srun -N 1 -n 1 -t 24:00:00 --mem=10G -C elves --pty bash
 
 > module purge
 > module load Spark
 > module load Python
 
 > source ~/.virtualenvs/spark-test/bin/activate

Watch the video 'Machine Learning Recommender System With Spark - Big Data Video 4' (slides are A_Recommender_System.pdf) Do the 3 exercises at 1:06 in the video and email Dan your answers and a summary of how you did on your own.

Demos and exercises can be run on the node you're on using pyspark-submit

 > pyspark-submit recommender.py

You can also start pyspark and use it interactively

 > pyspark
 >>>

The recommender.py script can be run using the job script sb.recommender

 > sbatch sb.recommender

Deep Learning with TensorFlow

Watch the video 'Tensorflow - Big Data Video 5' (slides are Deep_Learning.pdf) PSC has a version of TensorFlow that works on GPUs. The version on Beocat is newer, but works on the CPUs instead.

You can do the demos on Beocat if you want. There is a warning that the mnist data will be deprecated in the future.

 > module purge
 > module load TensorFlow
 
 > source ~/.virtualenvs/spark-test/bin/activate
 
 > python
