<div dir="ltr">Me and Lisandro just found a bug in the current implementation of ISGlobalToLocalMappingApply when bs>1. Please find attached a patch with a possible fix.<div><div><br></div><div>The issue is related with the convention used for the computation of the largest index in global ordering. In ISGlobalToLocalMappingSetUp_Private "end" is the largest index in global ordering, so the couple "start,end" defines a closed interval.</div><div><br></div><div>When it comes to map from global to local in ISGlobalToLocalMappingApply, indices larger the bs*end are not mapped back to local ordering, and thus the last bs-1 global indices are not mapped back.</div><div><br></div><div>Another possible fix would consist in changing the convention used for the computation of "end" (say, as the interval [start,end), more C friendly), but it will require more changes to the code, and maybe affect other part of the code where the private data of the ISLocalToGlobalMapping object is directly used.</div><div><br></div>-- <br><div class="gmail_signature">Stefano</div>
