Re: [OMPI users] Rounding errors and MPI

Hi, Is there an overlapping section in the MPI part ? Otherwise, please check : - declaration type of all the variables (consistency) - correct initialization of the array "wave" (to zero) - maybe use temporary variables like real size1,size2,factor size1 = dx+dy size2 = dhx+dhy factor =
