Dear all, I am trying to solve a huge linear system, which converges with open MPI and not with MPI. The problem is that I do not know what is the exact result. Thanks Diego On 16 February 2016 at 16:13, Eugene Loh wrote: > Which one is producing correct (or at least reasonable) results? Ar

Which one is producing correct (or at least reasonable) results? Are both results correct? Do you have ways of assessing correctness of your results? On February 16, 2016 at 5:19:16 AM, Diego Avesani (diego.aves...@gmail.com) wrote: Dear all, I have written an fortran-MPI code. Usually,

Dear all, I have written an fortran-MPI code. Usually, I compile it in MPI or in openMPI according to the cluster where it runs. Unfortunately, I get complitly a different result and I do not know why. Where could I look? Do you know why? Thanks Diego
