On investigation of parallelization effectiveness with the help of multi-core processors

AbstractThe article is concerned with the relevant problem of effective mapping of existing applications on multi-core processor computers. Numerical model of convective cloud is used as an application to be parallelized. The choice of the application is stipulated by the necessity of real-time forecast of the dangerous atmospheric phenomena such as thunderstorms, hails and rain storms by means of rather cheap desktop computers. Space parallelization in conjunction with the multi-thread technology has been used. Test numerical experiments have been provided on the multi-core processor computers of different types. Effectiveness of parallelizing has been investigated in relation to core and thread number
