We have a signal processing application built & running well under x86_em64t using IPP & ICC. I would like to port and test this application to take advantage of AVX. What is the build environment needed (OS, Compiler & IPP version)?
As it is a Signal Processing app, i assume it is using floating point data and is a good candidate for AVX. I wrote many signal processing algorithm using AVX.
Intel compiler 11.1+ is good. Win7 (or linux) will be right OS. As Win7 is not available with AVX support SDE canhelp you emulate the code.Latest IPP has many kernels ported to AVX.
One question, are you going to write AVX? or are you relying on compiler to generate AVX? Compiler can auto vectorize the code but it depends on the algorithms too.
Performance libraries such as IPP and MKL carry a greater advantage over compiled code with AVX. Optimized settings of affinity and number of threads carry increased importance.
