dnl HAVE_PARALLEL -- defined in H5config.h if we are building
dnl a parallel library even if configure wasn't
dnl able to find some header file or library that
dnl might be required. This is defined if the
dnl compiler looks like a parallel compiler (e.g.,
dnl mpicc or mpcc) or if the user explicitly states
dnl that a parallel library is being built by supplying
dnl the `--enable-parallel' configure switch.
dnl
dnl PARALLEL -- This variable is set to a non-null value if
dnl configure thinks we're compiling a parallel
dnl version of the library.
dnl
dnl RUNSERIAL -- This is a command which will be prepended to
dnl the executable name to run the executable using
dnl a single process. For serial versions of the
dnl library this will normally be empty. For parallel
dnl versions it might be something like `mpirun -np 1'.
dnl The value of this variable is substituted in *.in
dnl files.
dnl
dnl RUNPARALLEL -- This is a command which will be prepended to
dnl the executable name to run the executable on
dnl multiple processors. For the serial library the
dnl value will normally be the empty string. For
dnl parallel library it should be something like
dnl `mpi -np $$NPROCS' where NPROCS will eventually
dnl contain the number of processors on which to run
dnl the executable (the double dollarsigns are to
dnl protect the expansion until make executes the
