Hello,
I need to use DMPlexDistribute in a parallel finite element code.
I would like to know which partitioner can be used with this function.
I saw in an example that chaco is a possibility.
I tried to use parmetis instead but I did not manage to do it.

I was not looking at the latest version of the code (it seems online
documentation has not been updated yet).
Now, I can see that partitioner is used as an argument of
DMPlexCreatePartition.
However, there is a new argument: a PetscSF.
I have two questions about this new implementation:

I've just seen in DMPlexCreatePartition that only 'chaco' and 'metis' can be
used.

The 64 bit integers would at most double the memory usage. It should
actually be a bit less than doubling the memory usages since some of the memory
allocated in DMSetUp_DA() are doubles whose size would remain unchanged. Note
that switching to 64 bit indices would not increase the Vec

Exactly, I personally look for:
1) type checking during the function calls. This helps also not looking
into the manual for every single petsc function call.
2) low level access to petsc data structure. For example in my own code I
already have my own hadnling of parallel vectors and matrices.

internally ?
It tells the method what is necessary to evaluate stage derivatives, and
affects the starting method and (possibly) what can be carried over from
the last step.

1. You really need to profile. Copying a vector is cheap.
You are right. Maybe I make a big thing for this copy in/out and it is
not that problematic or slow even for the whole 2D matrix. I have to test
it with a large one to see.
2. If you make your functions (to evaluate residuals, etc)

Satish,
As far as I know, cygwin reads the Windows enviromental variable PATH. Can I
not change the the setting in in the Windows enviromental variables (since
other programs need them), but change the PATH used by cygwin only? Which file
should I change?
Thanks,

See $PETSC_DIR/bin/pythonscripts/PetscBinaryIO.py. You can read or
