mpiifort and 'end-of-file during read'

mpiifort and 'end-of-file during read'

Hi,

I'm trying to run an MPI code compiled with mpiifort. At the begenning of the code, while trying to open and read an ASCII file (the file is read by all processors)

file_name = 'Donnees_Simulation.dat'   
Open(11,File = file_name) 
Read(11,*);Read(11,*)

Unfortunately, I received this error where line 79 corresponds to the first Read applied to the imput file : 

mkdir ${tmpdir};cd ${tmpdir}
+ mkdir /san/home/fenni/tmp.748461
+ cd /san/home/fenni/tmp.748461
mpirun "${LOADL_STEP_INITDIR}"/myprog
+ mpirun '/san/work/fenni/Mycode/CodeFortranMPI/myprog'

forrtl: severe (24): end-of-file during read, unit 11, file /san/home/fenni/tmp.748461/Donnees_Simulation.dat

I find this, a little bizarre, since the same code run correctly on Windows with the intel compiler Composer XE 2013 and MPICH2 with the simple multi-purpose Daemon (SMPD) environment.

Can any one help please, Do this error has any relation with the compiler, did I miss any additionnal option ?

Thanks

Hi Ines,

I am unable to reproduce this behavior.  What Linux* distribution and filesystem are you using?  What version of the Intel® MPI Library and what compiler are you using?
