 Hi,

I am really really new to Fortran. I am     trying to find the best possible compiler for me and I am willing to pay     for it. I am little confused about the terms INTEL is using such as AVX     256bit vectorization. First of all, let me ask if Intel's Fortran supports     Quad precision ? I am working with matrices which are really     ill-conditioned therefore the more decimals the better for me. Second what     is this AVX doing is it a higher precision thing like Mathematica or Maple     has?

   

Thank you

Intel Fortran (and several others) support quad precision. AVX support (or other choices of architecture) don't enter into it, but may increase the relative performance penalty for quad precision.
