Using MSMPI.dll - fortran crash forrtl 157

 
 

I am trying to get a simple example working across 2 amazon nodes. When I run locally, its all fine. Then when I use -machinefile to launch across both nodes, the sample application on the slave node throws an exception. forrtl 157.  I can run using -machinefile and just run both locally. And I can run using -machine file and just run everything on the remote node. But when I add both addresses to the hosts.txt, it seems the sample application on the slave node crashes. Node names are the same as they are identical amazon images. I have tried disabling firewalls.  It always crashs when the slave node (or rank 1) calls MPI_SEND.  However, when I run with out -machinefile, and just run on the same machine,it all works fine with -n 4 etc.

Any pointers as to where I should start looking, thanks.

Here is my sample application:

  program hello
      include 'mpif.h'
      parameter (MASTER = 0)
 
      integer numtasks, taskid, len, ierr, rank, size,count
      character(MPI_MAX_PROCESSOR_NAME) hostname
      double precision data(100)
     integer status(MPI_STATUS_SIZE)
integer tag

 
 
     
     
!      write (*,*) 'Starting'
     
      call MPI_INIT(ierr)
      call MPI_COMM_SIZE(MPI_COMM_WORLD, numtasks, ierr)
      call MPI_COMM_RANK(MPI_COMM_WORLD, taskid, ierr)
     
     call MPI_GET_PROCESSOR_NAME(hostname, len, ierr)
     write(*,20) taskid, hostname
 

       if (taskid .eq. MASTER) then
        write(*,30) numtasks
       end if
 
        do i=1, 10
          data(i) = (i * (taskid + 1))
        end do
 
        count = 10
        tag = 666
 
        ! All slaves send back data
!        if (taskid >= 1) then
       if (taskid .ne. MASTER) then
            call MPI_SEND( data, count, MPI_DOUBLE_PRECISION, 0, tag, MPI_COMM_WORLD, ierr )
            write  (*,50) taskid
        end if
       
        count = 10
       if (taskid .eq. MASTER) then
         ! receive from each slave
           do i=1, numtasks-1
           call MPI_RECV(data, count, MPI_DOUBLE_PRECISION, i , tag, MPI_COMM_WORLD, status, ierr )
           write (*,40) i
           do j=1, count
               write (*,*) data(j)
           end do
         end do
       end if
      
      
      call MPI_FINALIZE(ierr)
 
20    format('Hello from task ',I2,' on ',A48)
30    format('MASTER: Number of MPI tasks is: ',I2)
40    format('MASTER: Received from: ',I2)
50    format('SLAVE:',I2,' : Sending to Master')
 
      end
HERE is what i see on the console
Hello from task  0 on WIN-MSDP9MK1V14
MASTER: Number of MPI tasks is:  2
Hello from task  1 on WIN-MSDP9MK1V14

It turns out that hostnames (not just IP address's) need to be different between machines.
