Yes.

OMP directives have been added to the  performance-critical routines.
The efficiency of the OMP parallelization depends on the  wks, compiler and
libraries available.

Since the compiler flags to turn on the OMP parallelization  are very much
dependent on the architecture and compiler used,
only the IBM xlf compiler settings for the SMP only or the mixed SMP-MPI
have been added.

The SMP version has however been tested on SGI wks (J. Hutter) and Linux
Red-Hat + Portland compiler.

Is CPMD SMP enabled?  Will it use both processors if two are present in a
workstation?

Thanks
