[petsc-users] Profiling objects creation

[SCOTTO Alexandre]

Hello Mat,

Thanks for your answer. I think this object is not available in petsc4py, at least I do not see any related elements in the documentation https://urldefense.us/v3/__https://petsc.org/main/petsc4py/reference/petsc4py.PETSc.html__;!!G_uCfscf7eWS!cDXOAoWknEhkWKDx0ghSlgUUMywVuLUCTz5sHEaHAVIJB_gsVlwjIfTb3qCF-mlz87Pdu0YEgddFhM80kaKVUDU_2z4ZrUvnN4KnKmo1uA$ 

So maybe this is not accessible in Python.

Regards,
Alexandre.

Dear PETSc community,

I am using the PETSc API petsc4py and I am interested in profiling the number of PETSc objects created during the run of my script.

I have used the -log_view option to get information on the run in a dedicated file, and I got this (among other infirmation):

This is precisely the information I am interested in, but here only the process 0 is tracked.

I is possible to have the same type of information for all the processes? I went through the documentation and was not able to figure it out.

You want to access

  https://urldefense.us/v3/__https://petsc.org/main/manualpages/Log/PetscLogState/__;!!G_uCfscf7eWS!cDXOAoWknEhkWKDx0ghSlgUUMywVuLUCTz5sHEaHAVIJB_gsVlwjIfTb3qCF-mlz87Pdu0YEgddFhM80kaKVUDU_2z4ZrUvnN4K-TsOjuw$ 

which you get using
