<pre><i><i>Dear Wien2k users,<br><br>I just compile WIEN2K in a PC-cluster, which is made by "Intel(R) Pentium(R) D CPU 3.20GHz".<br><br>The system I select is "Linux (Intel ifort 9 or 10 compiler + mkl 9.0 )"<br><br>Unfortunately, the machine do not install mkl. So the compiler options I use is:<br><br> O Compiler options: -FR -mp1 -w -prec_div -pad -ip<br> L Linker Flags: $(FOPT) -L../SRC_lib -lpthread<br> P Preprocessor flags '-DParallel'<br> R R_LIB (LAPACK+BLAS): -llapack_lapw -lblas<br><br>Using these setting, I can compile WIEN2K.
