请问这里的RP，FP和MP怎么样设置？谢谢。
我微机集群的配置Q6600四核。
intel ifort 编译器，安装位置是默认的

Howto-WIEN2k v 0.12 May 8 2006
=============================

0. make sure you got some good compiler and libraries,
e.g. ifort9 and mkl8 or later (free for academic use from intel)
on your computer

If you are the administrator of the computer update
'/etc/ld.so.conf' with paths to the libraries you are using:
/opt/intel/fc/9.0/lib
/opt/intel/mkl/8.0.1/lib/32
(just an example above) and run 'ldconfig'

check that the compiler is in your path
(if you enter 'ifort' is it found?)

1. copy a recent distribution of WIEN2k, for example
'WIEN2k_06.2_060309.tar' located at '/HOME/ikeno' on "earth"
or at '/home/weine' on "earth"

For the following steps also refer to the WIEN2k manual
=======================================================
also check http://www.wien2k.at/reg_user/index.html
for F.A.Q. and searching the WIEN2k mailing list

2. create a directory to install WIEN2k, for example 'WIEN2k/06.2'
move your tar-file there, expand files etc:
$ tar xvf WIEN2k_06.2_060309.tar
$ gzip -d *.gz
$ ./expand_lapw

clean up a bit by:
$ mkdir tars
$ mv *.tar tars

3. configure and compile WIEN2k by running
$ ./siteconfig
you can choose for example system 'J'
modify the settings 'O', 'L' and 'R',
I use the following compiler flags on a  64-bit Opteron system:
O (FOPT)    -FR -w -mp1 -prec_div -pad -ip -DINTEL_VML -O3 -xW
L (LDFLAGS)  -L/opt/intel/fce/9.0/lib -i-static -lguide_stats -lsvml -lpthread
R (R_LIBS) -L/opt/intel/mkl/8.0.1/lib/em64t -lmkl_lapack -lmkl_em64t -lguide -lpthread

on a 32-bit Pentium 4 system I just modify:
-FR -w -mp1 -prec_div -pad -ip -DINTEL_VML -O3 -xW
-L/opt/intel/fc/9.0/lib -i-static -lguide_stats -lsvml -lpthread
-L/opt/intel/mkl/8.0.1/lib/32 -lmkl_lapack -lmkl_ia32 -lguide -lpthread

you can also ask Ikeno-san for good compiler flags on your system
you might also try the default flags for system 'J' and check if they work
use the appropriate version of ifort, depending if you use 32-bit or 64-bit system
for itanium systems the compiler and flags would be a bit different
I found the flags I'm using by reading 'Fecher_CompileIntel.pdf'

the parameters NMATMAX and NMATMUL should reflect the RAM available on your
computer, e.g. on my 8 GB RAM opteron I used (though I'm no expert)
NMATMAX = 80000
NMATMUL = 8000
this also depends on

4. configure the user environment
$ ./userconfig
