Abstract
A parallel code for the numerical solution of second order ordinary differential systems without first derivative is developed, The code is mainly designed for solving large stiff systems with oscillatory solutions which require only a moderate accuracy, Then it can be specially useful to integrate systems arising from semi-discretization of second order hyperbolic partial derivative equations. The code is designed for distributed connection, with a ring topology, It is coded in parallel Fortran and uses the communication system EXPRESS. The code is robust, reliable and efficient, and achieves almost ideal values of speed-up and efficiency; and it is freely available on http://www.unisa.it/beapat.dir/soft/.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
