Hi,<br><br>
I don't have experience on P4 systems but I can tell you about some test
on AMD processors.<br>
The PGI compiler behaves very well, a little better then ifc+mkl.

For pgi compiler you can use:<br>
-Mfreeform -Kieee -fastsse -fast <br>
(for lapw2 just drop the optimization because the compilers get
hung!)<br><br>
xerbla.o must be add it at the end of the linking command.<br>
You will need this file only for a few of the executables not for
all.<br><br>
I have used also goto libraries and are the fastest so far.<br>
I have also an update for the benchmark list:<br><br>
<b>Opteron 1.6

<blockquote type=cite class=cite cite>I've been playing around with the

WIEN2k code, and have another entry for the list:<br>
P4, 3.2 GHz, dual channel mem. 258 sec (ifc7,

A second point, we actually purchased the PGI compiler, and it does
a<br>
rather poor job (benchmarks around 600 sec using the supplied
binaries<br>
for lapack and blas). Finally, I am curious about the
"goto" library;<br>
I tried a quick test, but it seems to be fussy about where to put<br>
xerbla.o - any suggestions about this as well as preferences for<br>
compiler flags? Thanks in advance.<br><br>
