Cheers to the wee Visualization of a Well-Log correlation!

Greetings from Edinburgh 🙂 During the past few weeks I have been able to finalize the project task that I have been assigned and I am very very excited for that. In a nutshell, a Python based code was developed

The end, or just another beginning?

As summer ends, I can’t help but rememb Jim Morrison (The Doors) singing “this is the end, my only friend, the end…”. This post also represents an end. It is the end of my Summer of HPC project and hence

The triple P conundrum

Pasta, pizza and ParaView are the topics I want to talk about in this post. As a Catalan guy, I’m used to the Mediterranean diet and it is impossible for me not to talk about food when staying in Italy.

Artificial Brains for enhancing Crowd Simulations?!

A visualisation of a biological neural network.

Hi all, In my previous post I introduced myself and the SoHPC programme. Now it’s time for my project. Why Crowd Simulation? Throughout history, humankind has had a clear preference for grouping together in larger and larger groups. On the global scale, 54

Development of sample application in PyCOMPSs/COMPSs

COMPSs is a programming model and runtime that aims at parallelizing sequential applications written in sequential programming languages (Java, Python, C/C++). The paradigm used to parallelize is the data-dependence tasks: the application developer selects the parts of the code (methods, functions) that will become tasks and indicates the directionality of the arguments of the tasks. With this information, the COMPSs runtime builds a data-dependence task graph, where the concurrenty of the applications at task level is inherent. The tasks are then executed in distributed resources (nodes in a cluster or a cloud). The runtime implement other features such as data transfer between nodes or elasticity in the cloud.

Visualization tool for olfactory bulb data

A clear understanding of the spatio-temporal dynamics of olfactory bulb mitral cells in representing an odor input is very difficult to achieve experimentally; for this reason, the activity-dependent effects of olfactory bulb network self-organization generated by the mitral-granule cell microcircuits remain poorly understood. To deal with this problem, we have constructed olfactory bulb microcircuits using realistic three dimensional (3D) inputs, cell morphologies, and network connectivity.

Exploring Mars Surface – 3D Visualization of post processed MARSIS data

MARSIS is a radar carried by the European Space Agency spacecraft Mars Express, and probing the interior of Mars to look for ice and water. To validate identification of echoes from subsurface structures, electromagnetic scattering from the Martian surface was simulated using HPC. Simulations will make it possible to use automated procedures to detect subsurface interfaces, or to study the correlation between real and simulated surface echo strengths to detect unusual surface properties.

Interactive Manipulation of Weather Regimes during Continuous Climate Simulations

The vision for this project is to create an interactive visualisation application that demonstrate how the particular weather and climate regime that we experience here on earth is just one manifestation of infinitely many other possible regimes, and how those regimes are determined by basic physical parameters like gravity, planetary tilt, the universal gas constant, and others. This will be done through interactive simulations of the atmospheric circulation on a rotating planet whose major physical properties can be changed arbitrarily. The application user can “play God” by moving sliders on a scale on the monitor with the mouse (with a slider for each adjustable physical parameter), and then immediately see the effect of their changes by viewing the resulting flow-field. The connection between each basic parameter and the way it determines the atmospheric circulation can be immediately visualised.

Enabling Real-Time Visualisations of Molecular Dynamics Properties in DL_POLY_4 (Proof of Concept)

This project has the goal of extending the widely used DL_POLY_4 molecular dynamics software package to enable 3D visualisations of molecular simulations in real-time, representing a significant advance for the DL_POLY code. The project will involve extending the DL_POLY_4 source code and will see the exploitation of state-of-the-art visualization toolkits.

Optimal deflation in the linear solver for lattice QCD

The student(s) will work in the Lattice QCD group of Prof. C. Alexandrou at CaSToRC in Cyprus.The task of the student will be to optimize deflation in the open source twisted mass code tmLQCD ( for the Blue Gene architecture.The student will write an interface so the eigenvectors produced using the tmLQCD code are written and reused for further computation. The student will investigate ways to optimise reading and writing (I/O) time, e.g. using compression or reduced precision.
