Hi all, I just pulled, reconfigured and rebuilt petsc-dev (changeset: 11135:7c2e5fab809d) and the 2 processor test failed with an error from PetscLogFlops (see error message below). The same configuration file works fine in the the latest release 2.3.3-p6. Not immediately critical, but I need petsc-dev for the PCDMMGDM routines (of which I'm still tracking down a pernicous bug, but am getting close). All help greatly appreciated cheers marc p.s. system is MacOSX 10.4.10, mpich2-1.0.5p4 -------------output of make test---------------------- Running test examples to verify correct installation C/C++ example src/snes/examples/tutorials/ex19 run successfully with 1 MPI process Possible error running C/C++ src/snes/examples/tutorials/ex19 with 2 MPI processes See http://www.mcs.anl.gov/petsc/petsc-as/documentation/ troubleshooting.html lid velocity = 0.0016, prandtl # = 1, grashof # = 1 [0]PETSC ERROR: --------------------- Error Message ------------------------------------ [0]PETSC ERROR: Argument out of range!
