  This is nonsense, they know better. Sure the convergence "decays", but no longer producing a positive definite preconditioner when the problem is positive definite is not due to "convergence decaying" it is much more fundamental; they are all good numerical analysts, they know this. They are basically saying that if you start with a positive definite problem which supports use of CG but use OpenMP threading then you need to switch to GMRES. That is a high price to pay; I suspect there is a bug in the code or that it is just not designed correctly but they don't want to deal with hunting down the issue. 

  The point is even if the smoother does absolutely nothing to improve the solution (it just copies the current value) it will not make the preconditioner operator no longer positive definite. So my conclusion is the smoother is broken since it does worse than nothing.  

  Do they propose a solution? Just not use  OpenMP threading for positive definite problems or always use GMRES when using OpenMP?

  I am not sure what to with your (and PETSc's) test cases in this situation. I guess the PETSc test could switch to GMRES when hypre is using OpenMP with a number of threads great than 1. But kind of cumbersome and annoying. 

  Junchao and Scott have some ideas on adding OpenMP threading to our CI tests. If we make sure this particular problem is in their then we will need to add a switch to handle it.

  I wish I had infinite time to fix these things. One could run it for a while until it "hangs" and then attach a debugger to the hanging process to see where it is. This would help determine the problem.

  Both for our testing and for our --download-openmpi configure option. I do not know if this is related to the problem at hand or not.
