VSC Training Course: Introduction to Working on the VSC-3 Cluster, April 27, 2017

    Description:

    This course is from beginners level (the first steps on a supercomputer) to intermediate level (some experience on VSC-3 or an other compute cluster).

    In this half-day course we will help you getting started on the VSC-3 cluster, Austria's most powerful supercomputer. With running and developing software on a supercomputer there are many similarities and fewer but crucial differences compared to your desktop PC. Focusing on hands-on teaching throughout the course, you will immediately try out what you've heard and adapt it to your own needs.

    This lecture is equally relevant to those who will merely be running existing software as to those who will develop scientific codes (however, without actually teaching supercomputer programming – if you would like to learn parallel programming, please refer to our MPI- or OpenMP-courses).

    Prerequisites:

    There is no previous knowledge required for this course.

    We suggest that you bring along your own laptop to benefit most from the hands-on exercises.
    Please make sure, that Opens external link in new windoweduroam is properly configured on your laptop, so that access to VSC-3 is possible during the course. If you use a Windows laptop please install the following software packages prior to the course: Opens external link in new windowPuTTY and Opens external link in new windowFileZilla or Opens external link in new windowwinscp.

    Alternatively, you can also work on one of the Linux PCs available in the course room, especially if this rather corresponds to your normal workflow.
