-------------- NOTE #1 --------------------------------------------------

 * DOUBLE COMPLEX
      We have an unknown bug with using vectors with pghpf in double
      complex precision.  Use a matrix declaration for a vector
      instead.
      i.e. use
             integer, parameter :: DP=kind(0.0D0)
             complex(DP) :: A(n,1)
      rather than
             integer, parameter :: DP=kind(0.0D0)
             complex(DP) :: A(n)

      Warning:  for an IBM SP2 the unknown bug appears with matricies
             as well
	
-------------- NOTE #2 --------------------------------------------------

 * TESTER DIES IMMEDIATELY AFTER STARTUP WITH MESSAGE
   "Must start PVM before calling ScaLAPACK routines"
      You must start PVM by typing "pvm" on one machine, and adding
      all machines that will have processes on them.  For instance,
      if you are running on two machines named BOB1 and BOB2, on BOB1
      you type:
         pvm
         pvm> add bob2
         pvm> quit
      See PVM homepage for more info, http://www.epm.ornl.gov/pvm/pvm_home.html.

-------------- NOTE #3 --------------------------------------------------

 * TESTER DIES IMMEDIATELY AFTER STARTUP
      Check to make sure you have allocated at least 4 processes, if running
      the default data files.  Otherwise, make sure you allocate however
      many processes are called for in your data file.

*************************************************************************
*************************************************************************

-------------- NOTE #1 --------------------------------------------------


 * MISSING SYMBOLS ON LINK:
      Check that you are linking to all required libraries.  If the missing
      symbols are system or Fortran library routines, one of your libraries
      may have been compiled with a compiler incompatible with your hpf
      compiler.  If so, recompile that library using a compatible compiler.
      If using the PGHPF compiler, on Linux systems it is important to recompile
      all of the F77 code with the PGHPF compiler.

*************************************************************************
*************************************************************************

-------------- NOTE #1 --------------------------------------------------

 * MISSING MPI LIBRARY:
      If you are using pghpf with the -Mmpi option, it will need to be told
      where to find your MPICH installation.  Set the environment variable
      HPF_MPI to point to your mpi library
      (e.g. setenv HPF_MPI /src/icl/MPI/mpich/lib/solaris/ch_p4/libmpi.a).

      NOTE: For pghpf version 2.4-4 this has a bug and you will need to
      have your system admin fix this before you can use it.
