Hello,<br>
Has any one installed petsc on the AMD 6200 series
processor systems? I have a small cluster with quad socket AMD
6274 (16Core) processors. Should i use any special optimization
flags or let petsc configure script decide ?<br clear="all">
<br>
I would like have two flavors of the instillation:<br>
<ol>
<li> intel 13.2 compilers using intel mpi and intel MKL 11.0</li>
<li> intel 13.2 compilers using intel mpi and ACML 5.3 compile
with intel. Now ACML has a weird organization of the
libraries. It has same names for both the 64bit and 32 bit
integer libraries but saved in different folders. Should i
link to single thread or multithreaded acml ?<br>
</li>
</ol>

I use <br>
--COPTFLAGS="-mavx -mfma4 -O3"<br>
--FOPTFLAGS="-mavx -mfma4 -O3"<br>
<br>
and single-threaded ACML optimized for fma4 instruction set ( i.e.
gfortran64_fma4/lib/libacml.a)<br>
Obviously, I use gcc and gfortran. All works fine. No need for Intel
on this machine. If you think gcc is much slower, just try with
optimization. <br>
