Hello Jose,
Thanks for your answer. Then it seems that I have under the hood usages of
setValues() in my code since I do not explicitly make use of it but
call

Dear PETSc community,
As a beginner in the MPI world and with the PETSc library, I come with a
possibly very naive question.
I know from the documentation that assembling vectors must be done, but it is
not clear to me when to perform this operation.
Is there a simple way to know when a vector n

Dear PETSc community,
I am currently struggling with the ADD_VALUE mode of the Scatter object. Here
is a simple piece of (Python) code to illustrate the issue:
vec_1 = PETSc.Vec().createMPI(size=10)
vec_1.shift(2.0)
vec_2 = PETSc.Vec().createMPI(size=10)
vec_2.shift(1.0)
index_set = PETSc.IS()

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):
