Data Science Lab

You will need an account to get started (contact the Lab Admin). This wiki will be updated as new capabilities are added.

• Python Anaconda is installed
• RStudio is installed
• Zeppelin Notebooks are now full configured for Python, PySpark, Spark, Hive, and shell programming. A notebook called Basic Tests (Python, PySpark, sh, and Hive) is available for learning more about Zeppelin (clone first).
• Transferring Files from the Cloud has been added. The rclone package has been installed on all workstations (rclone is a command line tool)
• Python Tensorflow (CPU and GPU) and Keras are installed

Watch this space for updates.

This computation resource is a collection of nine individual workstations that can work together as a scalable data science cluster for Big Data processing. The system can run large Hadoop and Spark jobs using the 10 TByte Hadoop Distributed File System (HDFS) on up to 120 cores. There are also three GPU equipped nodes that are configured to run TensorFlow. Total system memory is 600 GBytes spread across 30 separate motherboards.

Each workstation provides a Linux desktop environment that supports Anaconda Navigator (Python), Rstudio, and the Zeppelin web notebook (Spark, PySpark, Hadoop Hive,HBase, Python)
