Abstract. We consider a way to simplify of distributed computing system (grid) application in geophysics. Technical aspects of web-application design are emphasized, including details of integration of application specific parts into middleware. The work describes technical details of implementation of computing clusters and software we have created. The solution involved compute node visualization and application of modern programming techniques. As a pilot application we have implemented is determination of anisotropic parameters of crust and upper mantle with teleseismic data. The software allowed exact numerical solution utilizing a posteriori distribution function formalism. Consequently, acquired result was compared to results of similar task solved with approximate methods.
Keywords: inverse problem, mantle and core anisotropy, distributed computing systems, grid, grid application.
