Hi Vladimir, I'd like to contribute an optimization for GHASH Algorithm using AVX Instructions. I have tested this optimization on SKX x86_64 platform and it shows ~20-30% performance improvement for larger message sizes (for example 8k).
I, smita.kam...@intel.com<mailto:smita.kam...@intel.com> , Shay Gueuron, (shay.gue...@intel.com<mailto:shay.gue...@intel.com>) and Regev Shemy (regev.sh...@intel.com<mailto:regev.sh...@intel.com>) are contributors to this code. Link to Bug: https://bugs.openjdk.java.net/browse/JDK-8214074 Link to webrev: http://cr.openjdk.java.net/~svkamath/ghash/webrev/ For testing the implementation, I have executed TestAESMain.java. I have executed Jtreg tests and tested this code on 64 bit Windows and Linux platforms. Please review and let me know if you have any comments. Thanks and Regards, Smita
