MPIF90 running error “bad value during integer read”
1
There is a problem when I use the mpif90 compiler that complains that 'bad value during integer read'. However, when I use the gfortran compiler, there is no problem.
The gfortran version is
program main
implicit none
character*100 :: line
integer :: ierr, i
open(10, file="test.txt", action="read")
read(10, '(A)' ,iostat=ierr) line
read(line, "(6X, I5)") i
print*, i
end program
The mpif90 version is
program main
implicit none
include "mpif.h"
character*100 :: line
integer :: ierr, i, procID
call mpi_init(ierr)
call mpi_comm_rank(mpi_comm_world,procID,ierr)
if (procID==0) then
open(10, file="test.txt", action="read")
read(10, '(A)' ,iostat=ierr) line
read(line, "(6X, I5)") i
print*, i
endif
call mpi_finalize(ierr)
endprogram
the test.txt file contains that
TEST 1
- The
gfortranversion gives correct answer1 mpif90version usesmpif90compiler to compile the program and usempirun -n 4 ./a.outto run the program the outcome is
At line 12 of file read.f90
Fortran runtime error: Bad value during integer read
Why there is such a problem? Can anyone fix this?

mpif90might be anything. It is just a wrapper around some compiler. Please tell use which compiler it is. What doesmpif90 -vreturn? Which MPI library have you installed?

You are usingiostat=ierr, but then you are not checking the value ofierr. You can't do that. Either remove theiostator do check the value returned.

mpif90 -vreturns that "mpifort for MPICH version 3.2 gcc version 7.3.0 (Ubuntu 7.3.0-16ubuntu3)"

Thanks, I get it. I have used theanaconda's mpif90 which cause such problem. After reinstallMPICH, the problem is fixed. But I don't understand whyanaconda's mpi could cause such problem.
