Subject: [OMPI users] sun compilers

is there a searchable archive of this mailing list?

I am helping someone use Openmpi with Sun's compilers that came with
SolarisStudio. I used the --showme with mpif90 and got this

gfortran -I/opt/openmpi/include -pthread -I/opt/openmpi/lib ring_f90.f90
-L/opt/openmpi/lib -lmpi_f90 -lmpi_f77 -lmpi -lopen-rte -lopen-pal -ldl
-Wl,--export-dynamic -lnsl -lutil -lm -ldl

that line compiles fine and so does the mpif90 command but when I replace
gfortran with sunf90 or the absoulute path to my solaris studio compilers I
get this

$ f90 -I/opt/openmpi/include -pthread -I/opt/openmpi/lib ring_f90.f90
-L/opt/openmpi/lib -lmpi_f90 -lmpi_f77 -lmpi -lopen-rte -lopen-pal -ldl
-Wl,--export-dynamic -lnsl -lutil -lm -ldl
f90: Warning: Option -pthread passed to ld, if ld is invoked, ignored
otherwise
f90: Warning: Option -Wl,--export-dynamic passed to ld, if ld is invoked,

! Calculate the rank of the next process in the ring. Use the modulus
! operator so that the last process "wraps around" to rank zero.

  tag = 201
  next = mod((rank + 1), size)
  from = mod((rank + size - 1), size)

! If we are the "master" process (i.e., MPI_COMM_WORLD rank 0), put

     call MPI_SEND(message, 1, MPI_INTEGER, next, tag, MPI_COMM_WORLD, ierr)
     print *, 'Process 0 sent to ', next
  endif

! Pass the message around the ring. The exit mechanism works as
! follows: the message (a positive integer) is passed around the ring.
! Each time it passes rank 0, it is decremented. When each processes
! receives a message containing a 0 value, it passes the message on to
! the next process and then quits. By passing the 0 message first,
! every process gets the 0 message and can quit normally.

10 call MPI_RECV(message, 1, MPI_INTEGER, from, tag, MPI_COMM_WORLD, &
        MPI_STATUS_IGNORE, ierr)

  if (rank .eq. 0) then
     message = message - 1
     print *, 'Process 0 decremented value:', message
  endif

  call MPI_SEND(message, 1, MPI_INTEGER, next, tag, MPI_COMM_WORLD, ierr)

  if (message .eq. 0) then
     print *, 'Process ', rank, ' exiting'
     goto 20
  endif
  goto 10

! The last process does one extra send to process 0, which needs to be
! received before the program can exit

 20 if (rank .eq. 0) then
     call MPI_RECV(message, 1, MPI_INTEGER, from, tag, MPI_COMM_WORLD, &
          MPI_STATUS_IGNORE, ierr)
  endif

! All done

  call MPI_FINALIZE(ierr)
end program

Now, i must warn you, I don't know FORTRAN but I am supporting someone who
does. I have them CC
