Hi,<br>
<br>
PetscLogView does not display the same amount of information as running with -log_summary. In the "summary of stages" section, the former contains only information on the main stage while the later contains much more.<br>
<br>
Add the following block at the end of src/snes/examples/tutorials/ex1.c, for instance, to see what I mean<br>
PetscViewer viewer;<br>
ierr = PetscViewerASCIIOpen(PETSC_COMM_WORLD,"ex1-log.py",&viewer);CHKERRQ(ierr);<br>
ierr = PetscLogViewPython(viewer);CHKERRQ(ierr);<br>
ierr = PetscViewerDestroy(&viewer);CHKERRQ(ierr);<br>
ierr = PetscViewerASCIIOpen(PETSC_COMM_WORLD,"ex1-log.txt",&viewer);CHKERRQ(ierr);<br>
ierr = PetscLogView(viewer);CHKERRQ(ierr);<br>
ierr = PetscViewerDestroy(&viewer);CHKERRQ(ierr);<br>
ierr = PetscLogPrintDetailed(PETSC_COMM_WORLD,"ex1-logdetailed.txt");CHKERRQ(ierr);<br>
<br>
Is this a bug or a feature? Is there a way to get the same output as -log_summary in a file, without printing it to stdout?</blockquote><div><br></div><div>-log_summary just calls PetscLogView(). I am not sure how there could be a problem. I will run it. However, can you</div>
<div>just use</div><div><br></div><div> -log_summary <filename></div></div></blockquote><div><br></div><div>That works, yes. Is the issue that stages / events need to be activated a priori, which is not possible when PetscLogView is only called at the end of the program?</div><div><br></div><div>The caveat is that I am assuming that when using log_summary, the log is written as part of PetscFinalize, so that if a job is killed by the sceduler or the user, there is no way to get an idea of the performances. I like to print the log every so often.</div><div><br></div><div>Blaise</div><div><br></div></div><div apple-content-edited="true">
