Dear QE developer and users I am using an old cluster for calculation, where mpich2 1.2.1 was compiled by gortran 4.1.2 in Fedora 7 x86_64. The pw.x calculations were fine, but when I was executing ph.x, the iotk error occurred (no matter multi-nodes or single-core, this error occurred as soon as the input file read by ph.x) : # FROM IOTK LIBRARY, VERSION 1.2.0 # UNRECOVERABLE ERROR (ierr=1) # ERROR IN: iotk_scan_end (iotk_scan.f90:241) # CVS Revision: 1.23 # foundl # ERROR IN: iotk_close_read (iotk_files.f90:746) # CVS Revision: 1.20 As I known, such a problem is due to the bug of compiler, i.e., gfortran 4.1.2. However, since I just have the normal user authority in this cluster, I cannot upgrade gfortran or install other fortran compiler. Even mpich2 was installed in /usr, so I cannot re-compile it. In such a case, do I have to give up the phonon calculaitons in this cluster ?
