For reference yes thats correct Hugh. If you look through the Intel Assembly Manual it probably mentions it there . Through I don't think that Haswell has the SHA512 extension in hardware. Not sure when that was added but I believe it was in a later version. Nick --- Post to this mailing list talk@gtalug.org Unsubscribe from this mailing list https://gtalug.org/mailman/listinfo/talk
