[petsc-users] Running PETSC_DIR/src/snes/examples/tutorials/ex19.c

[Barry Smith]

  It appears that you are using the PETSc 3.1.8 RELEASE?  The directions for our GPU stuff http://www.mcs.anl.gov/petsc/petsc-as/features/gpus.html clearly state that it only works in petsc-dev. You must install petsc-dev to use the CUDA stuff.
