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。 5） 还报错 93 | call mpi_irecv(cellDatas(1,ibegg), 1, mpi_realType, iobj, itag, mpi_comm_world, requests(ic), ierror) | 1 ...... 187 | call mpi_irecv(cellDatas(1,ibegg), 1, mpi_realType, 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)). 6） gfortran -v Using built-in specs.

说点什么...
