Hi All,
I could integrate xenoncat’s solver into nheqminer.
Check my repo and let me know whether it is useful or not.
Follow instructions in README file.
If you feel this project is useful to you. Feel free to donate.

Sweet, thanks for doing this & sharing it publicly. Looks like it’s ~2.2x faster than the upstream nheqminer (tromp-based) solver on i7-4770k.
Equihash CPU Miner for NiceHash v0.1c
Thanks to Zcash developers for providing most of the code
Special thanks to tromp for providing optimized CPU equihash solver

Illegal instruction
@zcash111 are you running on Intel,linux,x86 processor?
Xenoncat’s code very specific to above config.
Linux Ubuntu-1604-xenial-64-minimal 4.4.0-38-generic
Intel 3770, # uname -p x86_64
@zcash111 You are running AVX2 code on a processor that does not support AVX2, hence Illegal instruction.
The solution is to recompile the miner, link with equihash_avx1.o instead of equihash_avx2.o
grep -r “avx” ./
./nheqminer/CMakeLists.txt:target_link_libraries({PROJECT_NAME} {LIBS} {CMAKE_THREAD_LIBS_INIT} {nheqminer_SOURCE_DIR}/equihash_avx1.o)
make[2]: *** No rule to make target ‘…/equihash_avx1.o’, needed by ‘nheqminer’. Stop.
make[2]: *** Waiting for unfinished jobs…
Download equihash_avx1.o from equihash-xenon/equihash_avx1.o at master · xenoncat/equihash-xenon · GitHub
Modified code to detect whether CPU supports AVX2 or not.
If CPU does not support AVX2, it falls back to tromp’s solver.
Nice. Get 12.6 sol to 20.

Àaaaaaaa
Many thanks,
with xenoncat’s I’ve 10,20 H/ and 19.3 Sol/s, as soon as I can I’ll a donation.
It works very well.
terminate called without an active exception
Aborted (core dumped)
Note: Im trying to run with flypool
Hi, still no CUDA miner on Linux?
This is a CUDA miner
Ah, great thank you!
I got it working for suprnova but can’t flypool
