Hello Anton, 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.
