C     Common header positions:
C 
C     XXI    ->  size of integer record
C     XXR    ->  size of real record
C     XXS    ->  status of the node
C     XXN    ->  node number
C     XXP    ->  pointer to previous record
C     XXA    ->  active fronts data management
C     XXF    ->  blr data passed from factorization to solve
C     XXLR   ->  Low rank status of a node (0=FR, 
C                                           1=LowRank CB only
C                                           2=LowRank factors/panels only
C                                           3=LowRank CB+factor/panel)
C     XXEBF  ->  End of Blocfacto (0=not yet, 1=finished)  
C     XXD    ->  dynamic data size
C     XXG    ->  GPU information (currently number of pinned rows NFRONT-NBROWS_CPU
C                for type 1 nodes, pinning status for type 2 strips)
C REMARK: .h file could be replaced by a module with functions to get node status
C          added in the module.
