[Wien] COMPILER OPTIONS??

[Shunli Shang]

Dear Nandan,

You can try GOTO's library, at present the new GOTO's lib for Itanium2 can
give the correct result.

I made a new test for the new GOTO's lib for the following Itanium2
processor:
Computer:             SGI Altix 3700 system (Intel Itanium2 CPU: 1.3GHz)
Operating system:  RedHat Linux
Compiler:              efc7.1: the Intel Fortran Compiler for Itanium
Libs:                     GOTO' lib for BLAS and MKL 6.0 for LAPACK.

Options to compile WIEN2K:
     O:    -FR -mp -w -O2
     L:    -L../SRC_lib -Vaxlib -openmp
     P:    '-DParallel'
     R:
   /home/shang819/wien2kgoto/SRC_lib/libgoto_it2p-r0.94.so -llapack_lapw

Test conditions:    THREADS=1, Single CPU.
Test results shown in the test_case.output1 file:
Maximum WALL clock time:    213.7   sec
Maximum CPU time:           2177.6 (should be 217.776 sec)

Best regards,
Shunli Shang
