I see. I'll sketch what I'm trying to achieve in case someone can
think of another approach.

I have some long-running SLEPc eigenvalue computations, and I'd like
to have SLURM signal my program that its time limit is drawing
near. In that case, my problem would set a flag and before the next
iteration of the SLEPc eigenvalue solver it would give up and save the
eigenvalues it has so far managed to obtain.

The only workaround I can think of would be to let my program keep
track of its time limit on its own and check it at each iteration.

There is no intention for PETSc to have handling of user-defined
signals?


Thanks.
