<p>Comment (by Roland Haas):</p>
<p>Please see also the discussion in <a data-is-external-link="true" href="https://github.com/EinsteinToolkit/ExternalLibraries-PETSc/pull/1" rel="nofollow">https://github.com/EinsteinToolkit/ExternalLibraries-PETSc/pull/1</a> where the error message is shown:</p>
<p>Right now with 3.12.5 (but not the version in the release) it fails the <code>charge_tatelliptic_petsc</code> test of CactusExamples/Poisson which uses TATelliptic and TATPETSc but not EllPETSc (which seems to be not used by any par or ccl file in the ET). On 2 MPI ranks the error produced by<code>charge_tatelliptic_petsc</code> is about differing scalar multipliers and an aXPlusY or so vector call, while on a single MPI rank the error is (the maybe more helpful):</p>
