Hi, I'm having problems same with this mentioned in https://software.intel.com/en-us/forums/intel-fortran-compiler-for-linux-and... as noted in the post, the problem is: "The MVAPICH2 2.0.1 build causes the bodies of a few FRTL routines to be included in the shared libraries (e.g. for_rtl_init in libmpichf90.so.12). The actual code is included, not just references to be resolved later. That code is out-of-date and so does not run correctly. The compiler legitimately puts a call to for_rtl_init, etc. into the generated code. The link step for MVAPICH2 must be resolving that to a static FRTL library which is not the actual up-to-date FRTL static library. If we are correct, then this is not a Fortran compiler problem, not a Fortran run-time library problem and not an Intel MPI problem. It is an MVAPICH2 build problem. --Patrick" But I cannot find any solution to it in that post, is there any workaround about it? Thanks in advance. Difu
