Hi all, I was trying to enable software prefetching on Opteron 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 processors with SSE4.2 and POPCNT instructions support." The CPU model is: model name : Quad-Core AMD Opteron Processor 2354 Does anybody know what is the correct compiler option for icc to enable s/w prefetching? Please let me know. Thank you Regards, Ram
