1) Fortran MPI_Comm won't work. Take an integer argument and use MPI_F2C calls to get the C-Comm object 2) ReadHeaderInfo - Does it need the pid ? 3) Reuse the comm object from the registration for both load and write operations. Do not take comm objects again to avoid confusion and retain consistency. 4) Decipher the global comm object and the subset partioning for each application based on the comm object 5) GetMeshInfo - return separately the owned and ghosted vertices/elements -- not together in visible_** but rather owned_** and ghosted_**. Make these arrays of size 2. 6) Should we sort the vertices after ghosting, such that the locally owned is first, and the ghosted appended next. 7) RCM only for the owned part of the mesh -- do not screw with the ghosted layers 8) GetBlockID - identical to GetVertexID -- return the global numbering for block 9) GetVertexID -- remember that the order of vertices returned have an implicit numbering embedded in it. DO NOT CHANGE THIS ORDERING... 10) GetBlockInfo takes global Block ID; Remove blockname unless there is a separate use case for it.. 11) GetElementConnectivity - clarify whether we return global or local vertex numbering. Preferably local numbering else lot of deciphering for global.
