Computational science Computational science Computational chemistry is a branch of theoretical chemistry whose major goals are to create efficient mathematical approximations and computer programs that calculate the properties of molecules (such as total energy, dipole and quadrupole moment, vibrational frequencies, reactivity and other diverse spectroscopic quantitities and cross sections for collision of molecules with diverse atomic or subatomic projectiles) and to apply these programs to concrete chemical objects. The term is also sometimes used to cover the areas of overlap between computer science and chemistry. ...more on Wikipedia about "Computational chemistry"
Computational epidemiology is the application of tools within the domains of computer science and medical geography to the study of the epidemiology of diseases. It differs from bioinformatics in that it is centered more around studying how diseases spread and not the actual disease itself. ...more on Wikipedia about "Computational epidemiology"
Computational neuroscience is an interdisciplinary field which draws on neuroscience, computer science and applied mathematics. It most often uses mathematical and computational techniques such as computer simulations and mathematical models to understand the function of the nervous system. ...more on Wikipedia about "Computational neuroscience"
A computer simulation or a computer model is a computer program that attempts to simulate an abstract model of a particular system. Computer simulations have become a useful part of modeling many natural systems in physics, chemistry and biology, human systems in economics and social science and in the process of engineering new technology, to gain insight into the operation of those systems. Traditionally, the formal modeling of systems has been via a mathematical model, which attempts to find analytical solutions to problems which enables the prediction of the behaviour of the system from a set of parameters and initial conditions. Computer simulations build on, and are a useful adjunct to purely mathematical models in science and technology and entertainment. ...more on Wikipedia about "Computer simulation"
A global climate model or general circulation model (GCM) aims to describe geophysical flow by integrating a variety of fluid-dynamical, chemical, or even biological equations that are either derived directly from physical laws (e.g. Newton's law) or constructed by more empirical means. There are both atmospheric GCMs (AGCMs) and ocean GCMs (OGCMs). When coupled together (along with other components such as a sea ice model and a land model) an ocean-atmosphere coupled general circulation model (AOGCM) forms the basis for a full climate model. ...more on Wikipedia about "Global climate model"
General-Purpose Computing on Graphics Processing Units (GPGPU, also referred to as GPGP and to a lesser extent GP^2) is a recent trend in computer science that uses the Graphics Processing Unit to perform the computations rather than the CPU. The addition of programmable stages and higher precision arithmetic to the GPU rendering pipeline have allowed software developers to use the GPU for non graphics related applications. Because of the extremely parallel nature of the graphics pipeline the GPU is especially useful for programs that can be casted as stream processing problems. ...more on Wikipedia about "GPGPU"
SAXPY (Scalar Alpha X Plus Y) is a basic operation in the field of computational science. SAXPY is a combination of scalar multiplication and vector addition, ...more on Wikipedia about "SAXPY"
Scientific computing (or Computational science) is the field of study concerned with constructing mathematical models and numerical solution techniques and using computers to analyse and solve scientific and engineering problems. In practical use, it is typically the application of computer simulation and other forms of computation to problems in various scientific disciplines. ...more on Wikipedia about "Scientific computing"
Scientific visualization is a branch of computer graphics which is concerned with the presentation of interactive or animated digital images to scientists who interpret potentially huge quantities of laboratory or simulation data or the results from sensors out in the field. ...more on Wikipedia about "Scientific visualization"
