This is at least 2x.

Wow, nice work.

What do I need to do? Thanks in advance

Ah - I haven't updated the no-chrono makefile

You can run by hand:

gcc intel/sha512_avx2.S -O3 -o obj/sha512_avx2.o

g++ -Wl,-z,relro -Wl,-z,now  -o ptsminer  obj/cpuid.o obj/sha512_avx.o obj/sha512_avx2.o obj/sha512_sse4.o obj/sha512.o obj/sph_sha2.o obj/sph_sha2big.o obj/main_poolminer.o  -Wl,-Bdynamic -l boost_system -l boost_filesystem -l boost_program_options -l boost_thread -Wl,-Bdynamic -l z -l dl -l pthread

Or try grabbing one of the newer, faster binary builds.

I'll patch up that makefile pretty soon.  Thanks for letting me know - I wasn't sure if anyone wanted to use it.

Thanks much. I nuked my post after finding the makefile and assuming I needed to comment out the avx2 code.

Going to try again --- here's the CPU output, which binary?

Thanks for your help. Understanding the CPU features and seeing this performance improvement is cool. Great stuff you are doing.
