 \section{Adding OpenMP support in addition to MPI}
 
-OpenMP support can be enabled in addition to MPI. However, in most cases performance will not improve
-because our pure MPI implementation is already heavily optimized. In many cases, the resulting code will in fact 
-be slightly slower.
+OpenMP support can be enabled in addition to MPI. However, in many cases performance will not improve
+because our pure MPI implementation is already heavily optimized and thus the resulting code will in fact 
+be slightly slower. A possible expection could be IBM BlueGene-type architectures.
 
 To enable OpenMP, uncomment the OpenMP compiler option in two lines in file \texttt{src/specfem3D/Makefile.in}
 (before running \texttt{configure}) and also uncomment the \texttt{\#define USE\_OPENMP} statement in file\\
