[Pkg-openmpi-maintainers] Bug#814183: openmpi 1.10.2 is broken on powerpc

I don't believe the warning below is related to the problem.

It can be avoided by changing the following line in petsc's debian/rules

export OMPI_MCA_orte_rsh_agent=/bin/false

to

export OMPI_MCA_plm_rsh_agent=/bin/false

Unfortunately this does not prevent the building ending with (as does aces3):

Build killed with signal TERM after 150 minutes of inactivity

On powerpc, running one of petsc's tests on one processor gets a
result (instantly):

$ mpiexec -n 1 ./ex19 -da_refine 3 -snes_monitor_short -pc_type mg
-ksp_type fgmres -pc_mg_type full
lid velocity = 0.0016, prandtl # = 1, grashof # = 1
  0 SNES Function norm 0.0406612
  1 SNES Function norm 3.33636e-06
  2 SNES Function norm 1.653e-11
Number of SNES iterations = 2

Running it on two processors never completes:

$ mpiexec -n 2 ./ex19 -da_refine 3 -snes_monitor_short -pc_type mg
-ksp_type fgmres -pc_mg_type full
lid velocity = 0.0016, prandtl # = 1, grashof # = 1
  0 SNES Function norm 0.0406612
