Error: Type mismatch between actual argument at (1) and actual argument

摘要: 1)问题call mpi_irecv( cellDatas(1,ibegg), 1, newType(ic), iobj, itag, mpi_comm_world, requests(ic), ierror) | 2Error: Type mismatch between actual argument at (1) and actual argument at (2 ...
1)问题
call mpi_irecv( cellDatas(1,ibegg), 1, newType(ic), iobj, itag, mpi_comm_world, requests(ic), ierror)
      |                      2
Error: Type mismatch between actual argument at (1) and actual argument at (2) (REAL(4)/INTEGER(4)).

2)问题分析
MPI_Irecv(Cin, 1, MPI_INT, my_rank - 1, 0, MPI_COMM_WORLD, &recv_request);

cellDatas是real, newType是整型。

  real, intent(inout) :: cellDatas(:,:)


  integer, allocatable :: newType(:), requests(:), statuses(:,:)

3)
int MPI_Irecv(void *buf, int count, MPI_Datatype datatype, int source, int tag,
              MPI_Comm comm, MPI_Request *request)
int MPI_Irecv_c(void *buf, MPI_Count count, MPI_Datatype datatype, int source,
                int tag, MPI_Comm comm, MPI_Request *request)
4)

newType(ic)可能是单精度,也可能是双精度。做了这样一个区分。

还报错

这个版本没有问题。

7)换版本
