The dipeptide kyotorphin (Tyr-Arg, Kyo) plays a role in pain modulation in the mammalian central nervous system (CNS), and is one of the most investigated neuropeptides. The Tyr-Arg motif exists widely throughout the brain not only as kyotorphin, but also as the N-terminal part of several endogenous analgesic peptides1,2. Also, this peptide is very rapidly degraded by aminopeptidases3. One of...

We developed an aplication that allows both the analysis of data and also the real-time visualisation on the same time. This is possible with the help of the GPU. To use the power of GPU is need of an specific framework (we use CUDA and OpenCL).
The aplication use data generated by UrQMD (Ultra relativistic Quantum Molecular Dynamics) to run a variety of algorithms and 3D visualization....

Feature extraction from satellite images has become a wide area of interest in the last two decades with the increase in the number of commercial earth observation satellites. This work focuses on extracting roads and cities from true color multi-spectral images that suffer from different quality problems like blurriness, increased amount of noise or abnormal color variations. To assist in the...

In this paper we present a collection of algorithms to generate power law mass distribution as initial conditions for gravitational N-body simulations. This type of algorithms are highly parallizable and can analyze large data customary on clusters. The input data will be high resolution images in the most used format in astrophysics, FITS and diffusion limited aggregation generated clusters....

Extended parametric resonances are one of the recurrent themes in the dynamics of quantum gases. Following some inceptive theoretical works Faraday waves have been observed in parametrically driven 87Rb BECs and 4He cells subject to vertical vibrations. These experimental observations have catalyzed the research activities and many theoretical investigations followed shortly. Among them we...

We report our results, obtained so far, in developing a novel, general two step genetic algorithm for finding an analytical solution of systems of ordinary differential equations, ant its generalization for solving more complex systems of ordinary and partial differential equations. We tested extended solution for solving several complex systems of different type of differential equations and...

GPAW software package implements efficient calculation of electronic structure of materials, based on the density functional theory and projector-augmented wave method. This C/Python code uses real-space formalism that allows flexible boundary conditions and efficient parallelization. Here we present results of the optimization of GPAW hybrid code (OpenMP and MPI). OpenMP performance traps are...

FermiQCD is a C++ library for fast development of parallel Lattice Quantum Field Theory computations. It has been developed following a top-down fully Object Oriented design approach with focus on simplicity of use. We present simulations for the hadron spectrum with the Wilson action in quenched QCD carried out on the BG HPC cluster, using this tool kit. Testing Fermiqcd as a tool kit for...

We have developed a program for counting self-avoiding Hamiltonian walks to run on multiple processors in a parallel mode. We study Hamiltonian walks (HWs) on the family of two-dimensional modified Sierpinski gasket fractals, as a simple model for compact polymers in nonhomogeneous media in two dimensions. We apply an exact recursive method which allows for explicit enumeration of extremely...

Development of an optimal medium power gas burner started under the FP6 project and was continued in HP-SEE project. CFD simulations were initially performed using FLUENT and partly StarCD Adapco sotware, but due to limited computing resources were limited to simulations of small segments with assumptions of absolute radial symmetry. In HP-SEE project we used OpenFOAM for full scale model...

Lattice Quantum Chromo-dynamics (LQCD) is an algorithmic formulation of QCD, the mathematical model that describes quarks and their interactions. Computations in LQCD are typically very expensive and run on dedicated supercomputers and large computer clusters for many months. In this paper the calculations are performed in one of the clusters for supercomputing of HP-SEE (High-Performance...
