This is documented in the man page for VecLoad() and
Thansk for all the replies.
I always thought that binary format would be best, but I couldn't find any
description of the binary format. Could you point me to a relevant piece
of the docs? Can I load the PETSC binary files into MatLab or DataExplorer
for further processing and visualization?

To complete your query - you'll also need a Vec with the same
communicator - i.e PETSC_COMM_SELF - for your approach to work. One
way to do this is:
VecGetArray(vec,&v)
VecGetLocalSize(vec,size)
VecCreateSeqWithArray(MPI_COMM_SELF,size,v,&seqvec)
VecView(seqvec,seqviewer)
VecDestroy(seqvec)
Vec
This is really a newbie question but I am struggling to solve out of memory
troubles on my first processor.
I have a parallel global vector, say v, that I obtain with a call to
DAGetGlobalVector. I save it to disk opening an ASCII standard viewer on
PETSC_COMM_WORLD and calling VecView. As I un
NEVER use ascii for large data sets. Use the binary viewer to save
them. See PetscViewerBinaryOpen().
