Hi Mark,
I've got an OLCF account but don't have access to Titan. Would it be
helpful for me to apply to get on whatever allocation you are using so I
can poke around at this stuff? (If so, send me a message off list with
details of what I should apply for.)
Hopefully I could get on there faster

We do have 2 variants of pgi compiers [linux, mac] in our test suite. [don't
know if PGI on titan is any

This example is marked as incompatible with pgf90.
However - if one invokes 'make ex73f90t' - this check

We are having problems compiling with PGI on Titan (pgf90 18.4-0 64-bit
target on x86-64 Linux -tp bulldozer-64). Any idea what is wrong here?
Thanks,

Vec and DM classes should not be visible from Sys. This is why they are
PetscObject.
If they were visible, builds with --with-single-library=0 will be broken.

Thanks all, I knew this but its been a while since I've run on this file
setup.

I'm looking at the VTK viewer implementation and I notice that
PetscViewerVTKAddField() [1]
accepts a parameter which, despite being called "dm", is of type
PetscObject.
I think that this is used, amongst other things, to ensure that vectors
being queued up to be written all come from the same

Try copying files to scratch file system.
Home is not available when executive batch job. Probably interactive she'll
too.

I can not even run a job here. This is from an interactive shell:
64-pgi ex19-batch1:~/petsc/src/snes/examples/tutorials> make
