  • Shared-memory Programming
  • Distributed-memory Programming
  • Scientific Visualization

High Performance Computing (HPC) is markedly changing the way we solve challenging problems in science, engineering, and society. From complex simulations to better understand the impact of climate change to sophisticated models to design effective drugs, HPC is a fundamental tool in accelerating time-to-discovery.

Building on the success of previous editions, the fourth installment of the Costa Rica High Performance Computing School (CRHPCS) aims at preparing students and researchers to introduce HPC tools in their workflows. A selected team of national and international experts will teach sessions on shared-memory programming, distributed-memory programming, and scientific visualization. 

We expect to continue with our mission to catalyze innovation through HPC with this event. Take advantage of this opportunity and join us for an exciting training.

Yuen Law


Biography: Yuen Law is a graduate in Computer Engineering from the Technological Institute of Costa Rica. In 2009 he obtained a DAAD scholarship to do his doctoral studies in Germany, at the RWTH Aachen. There he was part of the Virtual Reality Group, where he also developed his thesis project on the subject of medical simulation for training. After obtaining the doctorate, he continued in a postdoctoral position at the same university and then at the University of Trier, Germany. Recently he rejoined the faculty of the ITCR School of Computing.

Real-time simulation of ultrasound images:

In this talk we will see the role played by parallel programming (specifically CUDA) and the visualization of data in a real-time simulation pipeline of ultrasound images, which is used to create interactive training tools in medical procedures. The work presented is the result of a multidisciplinary research project with medical professionals, biomechanics experts and computer scientists. In the design of the simulation methodology, the physical behavior of both human tissue and ultrasound devices is imitated, trying to maximize performance to maintain interactive times, which is critical for training.


Greg Abram



Biography: Greg Abram received his PhD in Computer Science from the University of North Carolina at Chapel Hill, specializing in computer graphics, in 1986. He then spent several years in a small startup working on high-quality image synthesis before moving to the IBM TJ Watson Research Center. There he was a member of the architecture and development teams for IBM’s Visualization Data Explorer, which was the first visualization system designed specifically for high performance on shared-memory parallel systems. He then led its release into the open-source world and turned his attention to other visualization issues, including large-format displays and remote client-server systems, culminating in IBM’s Deep Computing Visualization suite of products. After twenty years at IBM he decamped to the Texas Advanced Computing Center at the University of Texas at Austin, where he works in large-scale distributed ray tracing for scientific visualization with colleagues at the Los Alamos National Laboratory and in virtual reality visualization with colleagues at the University of Minnesota (which he avoids in winter months).

Data visualization:

Data visualization generally divides into two classes – information visualization, which addresses the visualization of large sets of discrete data (the sorts of things typically stored in relational databases or spreadsheets) and scientific visualization, which addresses continuous space filling data represented on computational grids such as results from the simulation of physical processes (think weather or climate simulation, computational fluid dynamics or finite element analysis). This tutorial will address the latter, with particular attention to Paraview and VTK, which are used to visualize data on a wide range of scales spanning desktops to supercomputers. The tutorial will consist of half a day (or more) of introductory lectures on Paraview including basic principles and use, scripting and how and (more importantly why) we move to supercomputers. Once all are comfortable with the tools, we will then address a specific visualization task (or tasks) including aspects of data wrangling, or the transformation of data from the raw form produced by a simulation system to a form accessible by Paraview/VTK. Ideally, participants will bring examples of their data for us to work with; in lieu of that, we will look at data from the US Department of Energy’s MPAS-Ocean and MPAS-Ice simulations. Many digressions are to be

Diego Jiménez



Biography: Diego Jiménez is a  computer engineer graduated from the Costa Rica Institute of Technology. He currently works at the Advanced Computing Laboratory at CeNAT, where he conducts research in scientific computing and high performance computing. He has worked in projects of computational neuroscience and plasma physics  applying parallel programming techniques to accelerate simulations.  He has also studied the communication patterns present in large-scale MPI applications and their mappings to common interconnection topologies in high-performance computing. His research interests are: parallel programming paradigms and high performance computing. Diego will be in charge of teaching the Shared-Memory Programming sessions.

The Advanced Computing Laboratory (CNCA) at Costa Rica High Technology Center (CeNAT) is a multidisciplinary space where scientific discovery is accelerated through an advanced computing infrastructure. This infrastructure includes not only specialized and updated hardware, but also a set of efficient applications and well-trained staff in order to take  advantage  of  all  the  technology. This allows  CNCA  to work in the main dimensions of research, project development, training, and services provision.

The Pattern Recognition and Intelligent Systems Laboratory (PRIS-Lab) is part of the School of Electrical Engineering at UCR. We seek the generation of scientific research and technological innovation, towards integration between the academic community, the government, the productive sector, the civil society and the environment, to improve people’s quality of life. The specific interests of PRIS-Lab are mainly (but not limited to) pattern recognition, intelligent systems, machine learning, data mining, digital signal processing, digital image processing, motion capture, biocomputation, abstract data structures, algorithms and programmi  ng.
