Hi Matt,<br>
<br>
I did that in my 2nd attempt (as in the org email), but it only
shows 1 main stage in the end:<br>
<br>
I changed my code to only call PetscLogStageRegister once:<br>
<br>
<i>PetscLogStage stages(2)</i><i><br>
</i><i><br>
</i><i>call PetscLogStageRegister("momentum_eqn",stages(1),ierr)</i><i><br>
</i><i><br>
</i><i> call PetscLogStageRegister("poisson_eqn",stages(2),ierr)</i><i><br>
</i> <i><br>
</i><i> do time = 1,n</i><i><br>
</i><i> </i><i><br>
</i><i> ...</i><i><br>
</i> <i><br>
</i><i> call PetscLogStagePush(stages(1),ierr)</i><i><br>
</i> <i><br>
</i><i> stage 1 logging</i><i><br>
</i> <i><br>
</i><i> call PetscLogStagePop(ierr)</i><i><br>
</i> <i><br>
</i><i> </i><i>...</i><i><br>
</i> <i><br>
</i><i> call PetscLogStagePush(stages(2),ierr)</i><i><br>
</i> <i><br>
</i><i> stage 2 logging</i><i><br>
</i> <i><br>
</i><i> call PetscLogStagePop(ierr)</i><i><br>
</i> <i><br>
</i><i> end do</i><br>

<div bgcolor="#FFFFFF" text="#000000"> Hi,<br>
<br>
I am trying to log my PETSc performance in stages.<br>
<br>
I initially used:<br>
<br>
<i>PetscLogStage stages(2)</i><i><br>
</i><i><br>
</i><i>do time = 1,n</i><i><br>
</i><i> </i><i><br>
</i><i> ...</i><i><br>
</i><i><br>
</i><i> call
PetscLogStageRegister("momentum_eqn",stages(1),ierr)</i><i><br>
</i><i><br>
</i><i> call PetscLogStagePush(stages(1),ierr)</i><i><br>
</i><i><br>
</i><i> stage 1 logging</i><i><br>
</i><i><br>
</i><i> call PetscLogStagePop(ierr)</i><i><br>
</i><i><br>
</i><i> ...</i><i><br>
</i><i><br>
</i><i> call
PetscLogStageRegister("poisson_eqn",stages(2),ierr)</i><i><br>
</i><i><br>
</i><i> call PetscLogStagePush(stages(2),ierr)</i><i><br>
</i><i><br>
</i><i> stage 2 logging</i><i><br>
</i><i><br>
</i><i> call PetscLogStagePop(ierr)</i><i><br>
</i><i><br>
</i><i>end do</i><br>
<br>
<br>
The log_summary shows that results in stages 1 and 2, but
I also get the error:<br>
<br>
Invalid argument!<br>
[1]PETSC ERROR: Duplicate stage name given: poisson_eqn!<br>
<br>
I changed my code to only call PetscLogStageRegister once:<br>
<br>
<i>PetscLogStage stages(2)</i><i><br>
</i><i><br>
</i><i>call
PetscLogStageRegister("momentum_eqn",stages(1),ierr)</i><i><br>
</i><i><br>
</i><i> call
PetscLogStageRegister("poisson_eqn",stages(2),ierr)</i><i><br>
</i> <i><br>
</i><i> do time = 1,n</i><i><br>
</i><i> </i><i><br>
</i><i> ...</i><i><br>
</i> <i><br>
</i><i> call PetscLogStagePush(stages(1),ierr)</i><i><br>
</i> <i><br>
</i><i> stage 1 logging</i><i><br>
</i> <i><br>
</i><i> call PetscLogStagePop(ierr)</i><i><br>
</i> <i><br>
</i><i> </i><i>...</i><i><br>
</i> <i><br>
</i><i> call PetscLogStagePush(stages(2),ierr)</i><i><br>
</i> <i><br>
</i><i> stage 2 logging</i><i><br>
</i> <i><br>
</i><i> call PetscLogStagePop(ierr)</i><i><br>
</i> <i><br>
</i><i> end do</i><br>
<br>
Now there's no error but all logging are now grouped
together into just 1 main stage. <br>
<br>
How can I correct it to have separate logging? Tks!<span
