No, the matrix is not symmetric because of how we impose some Dirichlet
conditions on the boundary. I could easily give you the Jacobian, for one
of the "bad" problems. But at least in the case of RSLS, I don't know
whether the algorithm is performing badly, or whether the slow convergence
is simpl
Yes, that looks weird. Can you send me directly the linear problem (M, q, l,
and u)? I
will take a look and run some other diagnostics with some of my other tools.
Thanks, Todd.

Certain OpenMPI versions have bugs where even when you properly duplicate and
then free communicators it eventually "runs out of communicators". This is a
definitely a bug and was fixed in later OpenMPI versions. We wasted a lot of
time tracking down this bug in the past. By now it is an o

I know nothing about Vec FFTW, but if you can provide hdf5 files in your test,
I will see if I can reproduce it.

Hi Junchao/Barry,
It doesn't really matter what the h5 file contains, so I'm attaching a
lightly edited script of src/vec/vec/examples/tutorials/ex10.c which should
produce a vector to be used as input for the above test case. (I'm working
with ` --with-scalar-type=complex`).
Now that I think o
