You can see this in, e.g., $ git show 03c47c2df6d9113429 -- src/ksp/ksp/examples/tutorials/output/ex1_2.out which shows two spaces of trailing whitespace in the indented line. Matrix Object: 1 MPI processes I presume this was caused by somehow having petsc_history turned on, and I think the patch below will fix it, but I don't know how people turned on petsc_history to produce those trailing spaces in the first place. commit 17c4b54af62330efacf05d0471746d7cafbae154 (jed/fix-viewer-ascii-tab-whitespace) Author: Jed Brown <[email protected]> Date: Wed Jun 19 09:19:55 2013 +0200 Viewer ASCII: print tabs to petsc_history, not fd Tabs are intended to provide indentation, but were being printed as trailing whitespace when petsc_history was turned on. diff --git a/src/sys/classes/viewer/impls/ascii/filev.c b/src/sys/classes/viewer/impls/ascii/filev.c index 705f3f7..a90a521 100644 --- a/src/sys/classes/viewer/impls/ascii/filev.c +++ b/src/sys/classes/viewer/impls/ascii/filev.c @@ -554,7 +554,7 @@ PetscErrorCode PetscViewerASCIIPrintf(PetscViewer viewer,const char format[],.. va_start(Argp,format); tab = ascii->tab; while (tab--) { - ierr = PetscFPrintf(PETSC_COMM_SELF,fd," ");CHKERRQ(ierr); + ierr = PetscFPrintf(PETSC_COMM_SELF,petsc_history," ");CHKERRQ(ierr); } ierr = (*PetscVFPrintf)(petsc_history,format,Argp);CHKERRQ(ierr); err = fflush(petsc_history);
