Livermore scientists and collaborators accomplish three-dimensional, high-resolution simulations of whole-body blood flow on 1,572,864 cores of Blue Gene/Q, also known as Sequoia. Blood flow simulations of hemodynamics in the systemic arterial tree can potentially have a tremendous impact on the diagnosis and treatment of patients suffering from vascular disease.

This page lists available online tutorials related to parallel programming and using LC's HPC systems.

Useful introductory information on LC's software environment is presented in the Software and Development Environment section of the Introduction to Livermore Computing Resources, or the Linux Clusters Overview for system-specific information.

NICE DCV is a Virtual Network Computing (VNC) server that provides a securely authenticated and encrypted way for users to create and view a virtual desktop that persists even if no client is actually viewing it.


IDL (Interactive Data Language) enables in-depth data analysis through industry-leading visualization. IDL's interactive, high-level language can help you make discoveries and display your solution.

ImageMagick is a popular suite of open-source programs, libraries and headers used by programmers, scientists, and others to create images and to convert and modify existing images.

NCAR Graphics is a Fortran and C based software package for scientific visualization. It consists of routines for drawing contours, maps, vectors, streamlines, weather maps, surfaces, histograms, X/Y plots, annotations, and more.

ParaView is an open-source, multiplatform data analysis and visualization application. ParaView users can quickly build visualizations to analyze their data using qualitative and quantitative techniques.

This lesson shows you how to run ParaView with the client running on your desktop and the pvservers executing in parallel on the LC clusters. This tutorial assumes you are using a Macintosh or Linux desktop machine. If you are using Windows, it will still work, but you will need to use something like PuTTY to set up the SSH tunnel. Please contact the LC Computing Hotline at 2-4531 for assistance.
