Hi Peter,
Thank you for your email. Here is what I have so far:
```c++
// This will be filled in by looping over number of orbitals, with each
orbital containing an array of coefs.
struct Orbital_Data{
\\TODO: need a constructor that allocates memory for all the orbital's info
here?
private:
etc., must be in this
project.
I hope this added more clarity.
Thank you,
Zachary

Ah, I see and that makes perfect sense.
I'v been slightly exposed to TaskFlow and it's interesting y'all are
planning on using it. I will look more into this project!
Thank you,

So it does seem to be the Cmake version. The problem showed up with Cmake
3.19.1 and updating to 3.19.2 fixed it apparently. Wanted to share if
anyone else comes across this.

dsp( i, j ) = stuff_calculated
This gives me a local dsp and I thought the IndexSet add_range() above will
put this local dsp to the correct global index set.

Thanks Wolfgang,
I think you are correct! I just tried to use petsc_full_matrix instead and
it linked no problem!

Ah sorry, yes I have done that already. Sorry for forgetting that
detail...
If it should work assuming I have added my new directory in
source/CMakeLists.txt, maybe my implementation is the problem. Though, I
wouldn't know why since it fails at linking.

Ahh, I don't feel bad not thinking that possibility; brilliant!

Oh the test sees the number of processors from the .output files name?

My project is in quantum scattering and I would like to have some operators
be distributed PETSc objects. So inside my OneBodyHamiltonianOperator
class (for example), I would like to create a
PETScWrappers::MPI::SparseMatrix and then use SLEPC to solve for the ground
state and excited states.
Hello everyone,
I have a matrix A that has a sparsity pattern. I would like to take advantage
of that sparsity pattern and make a PETSc Sparse Matrix in CRS format from it.
My attempt is to go through the matrix A and have an if statement that saves to
a dynamic sparsity pattern when the
complained.)

That's what I have tried but I get the wrong spectrum. If that's what
you're recommending then I will crack on and debug.

Can you point me to the SparseMatrix::copy_from() that takes a FullMatrix?
I only see a copy_from() that takes in another SparseMatrix in the
PETScWrappers::MPI::SparseMatrix Class reference.

Oh very cool, thank you! I'll take a look at that.
Let's say my matrix gets huge, how would you tackle this? I'm expecting it
will, hence why I want CRS.

Oh really? I'm going to check it out right now! Debugging parallel

your take on it!

Hi everyone,
I have created a PETSc::MPI::SparseMatrix that has a global matrix distributed
across all the processes. I then pass it to SLEPc to solve for its spectrum.
I get the correct spectrum so I am pretty sure everything is correct. My
question is regarding strange behavior with more
