Hello Anton,<br><br>For me the problem is with gfortran. I use certain object oriented features available in Fortran 2003. When i last tested few months agao, my code does not compile with gfortran. I guess it is required/suggested to use the same compiler for petsc and the external code which uses petsc. Am i right ? My code relies heavily on zgemm which i use via direct call to lapack or via petsc. ACML also has ifort64_fma4 i was hoping they tweaked it to optimal performance on the new AMD processors. <br>
<br>Thanks<br>Reddy<br><br><div class="gmail_quote">On Tue, Mar 5, 2013 at 4:02 PM, Anton Popov <span dir="ltr"><<a href="mailto:popov@uni-mainz.de" target="_blank">popov@uni-mainz.de</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

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><div class="im">
