SGI EXTENSION: shmem_get
       C or C++:

          #define _SGI_SOURCE
          #include <mpp/shmem.h>

          void  shmem_get(void  *target,  const  void *source, size_t len, int
          pe);

DESCRIPTION
       The get routines  provide  a  high-performance  method  for  copying  a
       contiguous  data object from a different PE to a contiguous data object
       on a the local PE.   The  routines  return  after  the  data  has  been
       delivered to the target array on the local PE.

       The arguments are as follows:

       target    Local data object to be updated.

       source    Data object on the PE identified by pe that contains the data
                 to be copied.  This data object must be remotely  accessible.

       len       Number of elements in the target and source arrays.  len must
                 be of type integer.  If you are using Fortran, it must  be  a
                 constant, variable, or array element of default integer type.

       pe        PE number of the remote PE.  pe must be of type integer.   If
                 you  are  using  Fortran, it must be a constant, variable, or
                 array element of default integer type.

       The target and source data objects must conform to typing  constraints,
       which are as follows:

       Routine                       Data Type of target and source

       shmem_getmem                  Fortran:  Any noncharacter type.

                                     C:   Any  data  type.  len  is  scaled in
                                     bytes.

       shmem_get4, shmem_get32       Any noncharacter type that has a  storage
                                     size equal to 32 bits.

       shmem_get8, shmem_get64, shmem_get
                                     Any  noncharacter type that has a storage
                                     size equal to 64 bits.

       shmem_get128                  Any noncharacter type that has a  storage
                                     size equal to 128 bits.

       shmem_short_get               Elements of type short.

       shmem_int_get                 Elements of type int.

       shmem_long_get                Elements of type long.

       shmem_longlong_get            Elements of type long long.

       shmem_float_get               Elements of type float.

       shmem_double_get              Elements of type double.

       shmem_longdouble_get          Elements of type long double.

       SHMEM_CHARACTER_GET           Elements  of  type character.  len is the
                                     number of characters  to  transfer.   The
                                     actual  character  lengths  of the source
                                     and target variables are ignored.

       SHMEM_COMPLEX_GET             Elements of type complex of default size.

       SHMEM_DOUBLE_GET (Fortran)    Elements of type double precision.

       SHMEM_INTEGER_GET             Elements of type integer.

       SHMEM_LOGICAL_GET             Elements of type logical.

       SHMEM_REAL_GET                Elements of type real.

       If  you  are  using  Fortran,  data types must be of default size.  For
       example,  a  real  variable  must  be  declared  as  REAL,  REAL*4,  or
       REAL(KIND=4).

NOTES
       See intro_shmem(3) for a definition of the term remotely accessible.

EXAMPLES
       Consider this simple example for Fortran.

             PROGRAM REDUCTION
             REAL VALUES, SUM
             COMMON /C/ VALUES
             REAL WORK
             CALL START_PES(0)             ! ALLOW ANY NUMBER OF PES
             VALUES = MY_PE()              ! INITIALIZE IT TO SOMETHING
             CALL SHMEM_BARRIER_ALL
             SUM = 0.0
             DO I = 0,NUM_PES()-1
                CALL SHMEM_REAL_GET(WORK, VALUES, 1, I)
                SUM = SUM + WORK
             ENDDO
             PRINT*,'PE ',MY_PE(),' COMPUTED       SUM=',SUM
             CALL SHMEM_BARRIER_ALL
             END
