I have been using the Intel Visual Fortran Composer XE 2011 on my project and I found something weird recently. When I run the code in the debugging window, it produces perfect result; however, if the executable is moved to a different location and perform a standalone calculation (meaning not through the IDE) there, the result is totally off. I'm sure this is caused by the MKL because:
1) it is the only additional library my code uses, more specifically, only subroutine DGETRF and DGETRS are called, 2) a comparison of the correct and incorrect results indicate that the difference rises from the outputs of these subroutines.
I used to use the "Build IDE one button option" (http://software.intel.com/en-us/articles/using-mkl-in-intel-compiler-mkl-qmkl-options), so I thought the issue is that when the location changes, the code somehow cannot figure out where to find the library. Then I switched to the manual configuration for the MKL setup: I set the Intel MKL include dependencies (\<mkl directory>\include\ia32), the library dependencies in Linker > General (<mkl directory>\lib\ia32) and Linker > Input (mkl_intel_c.lib mkl_intel_thread.lib mkl_core.lib libiomp5md.lib mkl_lapack95.lib mkl_blas95.lib). All the procedures are given in the MKL user guide (http://download-software.intel.com/sites/products/documentation/hpc/mkl/...). I believe at least this will help the code locate the library because everything here is given by full path. Unfortunately, the problem exists.
I wonder if anybody has seen this before. Any help will be highly appreciated. Thanks very much for your time.
