simply store B as a normal assembled matrix with a standard row partition of the Lagrange multipliers. Then you would apply the subdomain solve operator using MatMultTranspose(B,XLambdaGlobal,XGlobal); for (i=0; ihttp://lists.mcs.anl.gov/pipermail/petsc-dev/attachments/20110420/5b89989f/attachment.html>

I think Jed pointed out a problem with the current approach. We don't really want to have MANSECs for each DM but we do want different include files. I forgot what Jed and I concluded but it could be that some makefiles need SUBMANSEC that appends onto the MANSEC. By the way it is DMDA n
