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>

Dharmendar,<br>

indeed, it's better to use the same compiler for everything. Which
gfortran version are you using? What is the option that is still
missing? According to this page
<a class="moz-txt-link-freetext" href="http://fortranwiki.org/fortran/show/Fortran+2003+status">http://fortranwiki.org/fortran/show/Fortran+2003+status</a> the Fortran
2003 standard support is fairly extensive. We use gfortran 4.7.2 and
a few features of Fortran 2003 in one of the applications. <br>
<br>
Also the -std=f2003 -ffree-form options should not be forgotten.<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">

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>

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>
