[Wien] Wrong compiling option ?

[zhao]

Dear Peter Blaha:

   I have compiled wien2k_0703 on an ibm machine(power 4; aix; xlf90)
and a cluster(Intel(R) Pentium(R) D CPU 3.40GHz; suse 10; ifort).I found
that the ibm machines consume more than four times computing time to
accomplish the same work than my cluster. I wonder if this is a normal
phenomenon, or I have use the wrong compiling option on the ibm machine.
Next I give my compiling options on the ibm machine. 

-------------------------------------------------
-------------------------------------------------
Current settings:
 O   Compiler options:        -O -q64 -qmaxmem=-1
 L   Linker Flags:            -L../SRC_lib -q64
 P   Preprocessor flags       '-WF,-DParallel'
 R   R_LIB (LAPACK
+BLAS):     /usr/lib/liblapack64.a /usr/lib/libblas64.a -qipa
---------------------------------------------------

Thank you very much.

Sincerely
