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
