[Wien] Help with Operation System

[M. Koshino]

Dear all,

In my opinion, xeon is not a new cpu so that it does not matter what OS you choose as long as your system and compilers properly recognize your hardware.

I recently set up a very cheap, new PC by myself and here is a note to encourage researchers of less funded.

When I first installed CentOS 5.6 on my core i7 2600 machine, the cpu was not properly recognized (there could be some ways but I easily gave up).
The intel compilers and other software were therefore not properly installed on the system with core i7 2600.

I could set up the latest intel compilers properly on fedora core 15, and could compile wien2k ver.11 (properly I hope).

System:
CPU: Core i7 2600 BOX
(recognized as processor 0-7: core i7-2600 cpu @ 3.40 GHz)
Motherboard: ASUS, P8P67 DELUXE REV 3.0
Video Card: ASUS, EAH5850 DIRECTCU/2DIS/1GD5 (PCIExp 1GB)
OS: Linux 2.6.38.6-27.fc15.x86_64
GNOME 3.0.1
memory: 16 GB
Corsair CMZ8GX3M2A1600C8 (4GBx4)
compiler
/opt/intel/composerxe-2011.4.191/bin/intel64/ifort
applying update 4.0 for C++ compiler XE 12.0, Fortran Compiler XE 12.0, Debugger 12.0, MKL 10.3, IPP 7.0, TBB 3.0.
(I could save $20K by comparing to my previous purchase from a high performance computer vendor.)

After running the test_case
command "x lapw1 -c"
test_case.output1:       TIME HAMILT (CPU)  =     6.5, HNS =     4.4, HORB =     0.0, DIAG =    25.4
test_case.output1:       TIME HAMILT (WALL) =     6.9, HNS =     4.4, HORB =     0.0, DIAG =    25.8

command "x lapw1 -p"
test_case.output1:       TIME HAMILT (CPU)  =     6.5, HNS =     4.4, HORB =     0.0, DIAG =    25.4
test_case.output1:       TIME HAMILT (WALL) =     6.7, HNS =     4.4, HORB =     0.0, DIAG =    25.6

after running the mpi-benchmark
command "x lapw1 -p"
Intel_core2_2.4_single_ifort-10_mkl-9.1.output1:       TIME HAMILT (CPU)  =   200.5, HNS =   154.5, HORB =     0.0, DIAG =   923.7
mpi-benchmark.output1:       TIME HAMILT (CPU)  =    91.0, HNS =    50.6, HORB =     0.0, DIAG =   300.0
mpi-benchmark.output1:       TIME HAMILT (WALL) =    91.8, HNS =    51.0, HORB =     0.0, DIAG =   303.4

I am not familiar with the values here so I hope someone will make a comment on this.

Kind regards,
