John -- I am unable to replicate your problem with Open MPI 1.0.2 with the following simple program:
----- program ring_f77 include 'mpif.h' integer n, rank, size, ierr real*8 data2(10), data(10) call mpi_init(ierr) call mpi_comm_rank(MPI_COMM_WORLD, rank, ierr) call mpi_comm_size(MPI_COMM_WORLD, size, ierr) n = 10 call MPI_Allreduce( data, data2, n, MPI_DOUBLE_PRECISION, & MPI_SUM, MPI_COMM_WORLD, ierr ) call mpi_finalize(ierr) end ----- Can you replicate the problem with this small program? > -----Original Message----- > From: users-boun...@open-mpi.org > [mailto:users-boun...@open-mpi.org] On Behalf Of john casu > Sent: Thursday, April 06, 2006 6:07 PM > To: Open MPI Users > Subject: Re: [OMPI users] MPI_Allreduce error in 1.0.1 and 1.0.2rc1 > > On Thu, 2006-04-06 at 15:48 -0400, George Bosilca wrote: > > The error state that your trying to use an invalid operation.
