Page numbers are Acrobat page numbers, not document page numbers. Page9_at_19: ...count values, and that type is MPI_Count... Page9_at_29: confusion about 'type map' applying to memory only, not file view Page9_at_30: For backward compatibility, many MPI routines use int in C or INTEGER in Fortran as count arguments. Page24_at_9: MPI_COUNT should be MPI_Count Page91_at_11: "value of size to" size should be a different font. Page92_at_15: Add "The Functions MPI_TYPE_GET_EXTENT" Page94_at_33: Start sentence properly, not with 'true_lb' (Ticket0 for Adam) Page120_at_38: Use similar wording to previous "limits" wording might be better (more consistent) Need to mention overflow for MPI_GET_COUNT? One could use MPI_STATUS_SET_ELEMENTS_X to overflow MPI_GET_COUNT. In MPI Forum 3.0 draft 1 document: Page455_at_32 add MPI_COUNT as width = 8 in external32
