    enabling s/w prefetching


      Hi all,


      I was trying to enable software prefetching by compiling an application using Intel compiler. But  I am facing some problem.


      I use the below compilation command.

      -> icc  -openmp -O3 -xsse4.2 -opt-prefetch=4 is.c


      But when I run the program I get the below error.

      "Fatal Error: This program was not built to run on the processor in your system.

      The allowed processors are: Intel(R) processors with SSE4.2 and POPCNT instructions support."


      The CPU model is:

      model name: Quad-Core AMD Opteron(tm) Processor 2354


      Does anybody know what is the correct compiler option for icc to enable s/w prefetching? Please let me know.


      Thank you
