I am not able to find that example, did you mean to spell it with an "x"? Could you provide a link to the page you're looking at.
I am using http://www.netlib.org/scalapack/explore-html/d9/d92/pzgetrs_8f_source.html for my reference. I do basically everything they do, but I do replace the IA, JA, IB, JB entries with a fixed number "1". Would that be an issue? The issue I believe is my inability to read in the pivot array using MPI-IO darray type. It mentions that reading a vector in MPI IO darray requires the pdims(1) or pdims(2) to be one. That might be why the pivoting is not working.
I need help creating/feeding in a matrix (distribute it) and have MPI-IO read in a binary file Nx1 sized vector. If I don't have to use MPI-IO I don't see this issue. So, I believe what I am seeing is MPI-IO. Are there any examples of MPI-IO using PZLAPIV?
My question is how to read MPI-IO fortran unformatted data into a IPIV structure?
