If you're not using threaded IPP functions and you have an OpenMP compatible compiler, you could use OpenMP (parallel sections if I recall correctly) to do the threading yourself ; this will lead to run the functions concurrently on your process. IPP is thread safe so you can call functions from different thread given that the arguments you pass don't go against basic multithreading rules (ie, passing the same destination buffer for 2 functions running concurrently).<BR /><BR />Hope this helps,<BR />Matthieu<BR /> Thu, 12 Nov 2009 12:49:35 GMT matthieu_darbois 2009-11-12T12:49:35Z https://community.intel.com/t5/Intel-Integrated-Performance/Concurrent-Asynchronous-IPP-Functions-in-a-single-executable/m-p/886422#M10881 Hi, <DIV><SPAN style="font-family: Verdana, Arial, Helvetica, sans-serif;"><BR /></SPAN></DIV> <DIV>I have been developed my applications using IPP functions for quite some time and, have benefited the performance gain from the functions.
