Hi,
Here is an update. The code crashes only when it is launched by
mpirun, and the actual piece of code where it happens is this:
IF ( ionode ) THEN
30 READ (parse_unit, fmt='(A256)', END=10) line
IF( line == ' ' .OR. line(1:1) == '#' ) GO TO 30
tend = .FALSE.
GO TO 20
10 tend = .TRUE.
20 CONTINUE
END IF
Basically, the 1st node is supposed to reach the end of file while
reading in a file, and jump to line "10". Instead, it crashes at line
30 with the message "forrtl: severe (39): error during read, unit 5,
file /dev/ptmx".
If I add a keyword to the end of the file "END", and then never let
the program see the end of file, it works fine.
Is there a patch for Open-MPI that would fix that?
Thanks!
Konstantin
