I agree with Steve. In these sorts of calls the actual size of the array is available from somewhere else - either another argument or information in the communicator. This is the common situation when calling C. Cheers, Bill On Mar 10, 2014, at 11:06 AM, Junchao Zhang <[email protected]> wrote:
Hello, I read a Fortran textbook, which says "Assumed-size dummy arrays are a holdover from earlier versions of Fortran. They should never be used in any new programs". But I find MPI3 has interfaces like MPI_Alltoallv(sendbuf, sendcounts, sdispls, sendtype, recvbuf, recvcounts, rdispls, recvtype, comm, ierror) ... INTEGER, INTENT(IN) :: sendcounts(*), sdispls(*), recvcounts(*), rdispls(*) ...
I was wondering why MPI3 still uses it. Thanks.
