Quoting - tim18 Rather than everyone asking you what you intend to do, it's more productive for you to use the resources provided, then ask questions. Hello Tim18! May be I am not smart enough, but I could NOT find the information necessary to answer my questions in Intel's documentation. I also can not see the reason why this simple and purely technological knowledge should be a kind of magic. Why should I even ask these question...

Quoting - Dmitry Baksheev (Intel) Hi Craig, Replacing use of FFTW3 interface with use of DFTI interface will not give noticeable performance advantage. However, you may get improved performance if you plan for multiple transforms in a single call of dfftw_execute instead of executing single transform in the loop. Could you look at DFFTW_PLAN_MANY_DFT_C2R, and rearrange your code to something like this: call...

Hi, If you call Fortran 95 interface, you should use generic name: call gesv( A, B) and USE statement (Use lapack95 , Only: gesv) Then ensure "<mkl_directory>\include\ia32" directory is set or simply add it in the Additional Include Directories window. And you need link also mkl_lapack95.lib library. In case of 64 bit architecture the additional include directory should be...

Thanks!! The $MKLROOT was already providing the proper path to the MKL. Using the makefile did the trick. Now it compiles fine. This is what I used to make: make libem64t...

Hi Michael, We know about this issue. In general, the TR solvers are solvers for nonlinear optimization problems, but your objective function is linear. In some casesth the TR solvers may work incorrectly for problems with linear objective functions with boundary constraints. We've fixed this issue so TR solvers work correctly for such types of problems. This fix ...

Hi, Your configure script is looking for FFTW2 library and complaints it cannot find it to continue. There are several options to fix this. You may download and install FFTW2.1.5 from fftw.org before running mpgrafic/configure - this shoul be easy. You may use MKL's FFTW2 wrappers that can be found in interfaces/fftw2xf directory - this is a little bit ...
