Dr Mark BullMy principal responsibilities in EPCC are in the areas of research and education. My current research interests include the applications and benchmarking of shared memory parallel computers, and the use of Java for high performance computing. Most of my research is carried out as...
HPC & the Inventor's dilemma: Abandoning 15 years of Molecular Simulation Work to Move to GPUs
06 Sep 2013 | Online Presentations | Contributor(s): Erik Lindahl
Alternate Title:Parallel molecular dynamics - how we evolved from 10 cores to heterogeneous GPU acceleration and petascale parallelizationMolecular dynamics has come a long way the last 20 years; what was once a small esoteric technique in theoretical physics is now a standard tool of molecular...
Astrophysics: How to simulate the most catastrophic events in the universe
09 Sep 2013 | Online Presentations | Contributor(s): Luciano Rezzolla
I am a relativistic astrophysicist: i.e. a physicists that uses Einstein's theory of general relativity to describe and explain astronomical observations of black holes and neutron stars. To do this I combine analytical perturbative tools with numerical nonlinear simulations in which I solve the...
Quantum Chromodynamics on a space-time lattice – building up the femto universe of atomic nuclei on a computer
09 Sep 2013 | Online Presentations | Contributor(s): Akira Ukawa
Everyone knows that all atoms are made of atomic nuclei and electrons around them, and that atomic nuclei are made of protons and neutrons bound by pions. Every scientist would know that protons and neutrons in turn are made of quarks, and are bound by gluons. Not every scientist may know,...
10 Sep 2013 | Online Presentations | Contributor(s): John Urbanic
John Urbanic is Parallel Computing Specialist at the Pittsburgh Supercomputing Center where he spends as much time as possible implementing extremely scalable code on interesting machines. These days that means a lot of MPI, OpenMP and OpenACC. John also enjoys Big Data challenges which involve...
Modern GPU Programming with CUDA and Thrust
12 Sep 2013 | Online Presentations | Contributor(s): Gilles Civario
Today's GPUs are massively parallel devices which provide programmers with TeraFlops supercomputing performance. But programming these devices and exploiting their fantastic potential is not always easy and might discourage application developers. CUDA for example is too often seen as a very low...
HPC & Life Sciences
19 Sep 2013 | Online Presentations | Contributor(s): Thomas Cheatham
Biomolecular simulation provides a means to explore biomolecular structure, dynamics and interactions on timescales from femptoseconds to milliseconds on available high performance computing computational resources. Since the first protein simulations in ~1975, atomistic molecular dynamics (MD)...
HPC Software Engineering: "Do as I say, not as I do"
19 Sep 2013 | Online Presentations | Contributor(s): Erik Lindahl
Most scientific software projects started as a quick hack on somebody's laptop, but before you know it there might be dozens of future students and postdocs involved. However, unlike 30 years ago, today few of us are only one supercomputer from a single vendor providing a single compiler. Many...
