CryptonightR testing (second round) #5

Open SChernykh opened 5 years ago

SChernykh commented 5 years ago

Test results will be collected here. Please post your hashrate and power consumption (if you can measure it) compared to latest xmrig/xmrig-amd release on CryptonightV2.

1-2% hashrate drop is normal because CPU/GPU miner code is not fully optimized yet. In case there is a significant hashrate drop on some hardware, we have an option to reduce random math size appropriately.

GPU tests

AMD Radeon RX 560 on Windows 10 1809: core @ 1196 MHz, memory @ 2200 MHz, 1 Click PBE Timing Straps, 18.6.1 drivers, monitor plugged in, 2 threads (intensity 512, worksize 32, strided_index 2, mem_chunk 2, unroll 8):

AMD Vega 64 (stock, 2 threads, intensity 1920, worksize 16, strided_index 2, mem_chunk 2, unroll_factor 8):

CPU tests

AMD Ryzen 5 2600 @ 4 GHz, single thread:

I've been experimenting with Ryzen a lot, and this variance doesn't come from random math directly, it's somehow related to subtle instruction decoding stalls that happen for some code sequences. But I know how to fix it, it'll just take some more time.

Intel Pentium G5400 (Coffee Lake 3.7 GHz, 2 threads):

Intel Core i7-2600 (Sandy Bridge 3.4 GHz, 4 threads):

Dual AMD Opteron 6276 (16 physical cores, 24 threads)

Fluctuations are much smaller now compared to the first version.

SChernykh commented 5 years ago

Did you test it for only 1 minute? You probably hit one of the slowest code sequences. Core 3 is also 9 H/s faster than other 3 cores which shouldn't happen - something was probably running in the background and spoiled test result.

Does testnet always reject shares? Just let me know... I have a few cpu's i can test and provide feedback

SChernykh commented 5 years ago

@jorgealonso108 It shouldn't reject shares. Did you compile the latest version?

Edit: I've compiled it using GCC 7.3.0 on Ubuntu 18.04 and GCC 8.2.1 on Windows 10 (MSYS2 build) and both builds worked fine, all shares were accepted.

jorgealonso108 commented 5 years ago

I'm on Ubuntu 18.04 clean/fresh install....I have used the same version miner "XMRig/2.8.5-dev gcc/7.3.0" on other pools and have had no problems, its actually the first time I have seen that error...I don't really know what it means, but i would like to help fix the problem. Maybe latency to the pool? i.e. (569 ms) (507 ms) I can try it on a few cloud vM's closer to the pool? Maybe pool software? I do mine wownero and monero, cpu's only...let me know what i can do to help?

SChernykh commented 5 years ago

@jorgealonso108 How exactly did you compile it? Did you do

git clone https://github.com/SChernykh/xmrig.git
cd xmrig
git checkout CryptonightR
mkdir build
cd build
cmake ..
make

???

jorgealonso108 commented 5 years ago

No...I compiled it from download zip folder...not with git clone I get this error with the above instructions...git checkout error?

Please, if you can send me git clone exact instructions...I will follow them exactly. I was use xmrig, love it, never have a problem. I must be doing something wrong?

@jorgealonso108 I edited my post above: cd xmrig shoud be done before git checkout - you can try again.

SChernykh commented 5 years ago

@nssy Do you have any double threads in your config? Double hash code for cn/r is far from optimized yet. Can you test both algorithms only with single threads?

nssy commented 5 years ago

No double hash threads used.

SChernykh commented 5 years ago

@nssy Still, you have 32 threads on only 28 physical cores, so 4 cores run 2 single threads each. This configuration is much slower because single thread already uses 80% of a single CPU core compute capacity. I'll need to implement double thread using SSE instructions to fix this slowdown.

nssy commented 5 years ago

Ok I have run both with 28 threads instead.

I've tried Opteron 6276. With single thread I got

Single Thread: 53H/s

When invoking 24 Threads I got:

24 Threads: 760H/s

But 760:24=31,66H/s

Something is woring, I tried all settings I could but got no better performance.

Does someone has a solution?

SChernykh commented 5 years ago

Opteron 6276 has 8 core modules and 16 MB L2 cache, dual system has 16 modules and 32 MB L2 cache, but you run 24 threads - it's more than it can handle without dropping single thread performance.

numerys commented 5 years ago

Sorry, I did not mention that it is a dual board. 2 x Opteron 6276 inside a HP dl165 G7. In total 16 cores/32 threads.

SChernykh commented 5 years ago

More than 1 thread (or scratchpad) per core is not optimized yet. I'll be working on optimized double hash code this and next week, so you can expect some improvement when it's done.

@gvgit My first attempt to make fast double hash version using SSE failed - it wasn't faster than current code, so I have to think again.

SChernykh commented 5 years ago

@gvgit I've tried different approach for double hash SSE version and it seems to work, at least on Intel processors. I'll keep experimenting, but chances are good that double hash performance will be improved.

I am just about to test some more CPU's and post results.

What is "cn/half" algo ?

What is "cn/half" algo ?

It's not related to this testing. It's CNv2 with half iterations used in some recent coin forks.

Any success on double hash SSE regarding AMD CPUs?

SChernykh commented 5 years ago

The results are mixed. As soon as I fixed all bugs in the code, it wasn't faster on Intel and was a bit faster on Ryzen (but Ryzen doesn't need it since two single threads on the same core are still faster). I haven't tested it on older AMD processors yet. Double hash SSE version (test code) is available in https://github.com/SChernykh/CryptonightR - but it requires Windows + Visual Studio to compile and run.

New success on Opterons?

SChernykh commented 5 years ago

@gvgit Opterons are already faster with CryptonightR than they were with CNv2. I'm not sure SSE would help them because they have only one FP unit per 2 cores, but each core has integer unit. I still need to implement SSE code in xmrig to test it thoroughly.

numerys commented 5 years ago

@SChernykh CNv2 was a knockout for Opterons. If the hashrate won't get back to 1kh/s for a dual opteron system it will likely be the end for Opterons.

I have compiled XMRig on Ubuntu 16.04 successfully with these commands:

git clone https://github.com/SChernykh/xmrig.git cd xmrig git checkout CryptonightR mkdir build cd build cmake .. make

I now have a xmrig file in the build directory but have no idea how to run it for testing?

The only instructions for configuration is this text:

Usage

Use config.xmrig.com to generate, edit or share configurations.

That seems to reference a Windows program. So again please help me to get this running for testing on my HP DL580 and AMD R815 servers.

@kio3i0j9024vkoenio For CN/R ./xmrig --max-cpu-usage 100 -o testnet.wowne.ro:3333 -u 9zuKdp6MrQaBSw85QP2fFh8zznN8tPbpJQZhX6wyVGHb5TdJu4QYcPK7EtfhUtnYbVUCFkNM9sPfViN5HvmXxV9iEVJP2o8 -p x -k You will need to configure threads accordingly.

Ryzen 7 1700 around 450H/S with 8 threads on latest xmrig (cn/wow)

@SChernykh, I don't know how many ARMv8 miners are out there, but just to let you know... it seems that CN/R has a big impact on ARMv8

Using xmrig 2.13.1 built with gcc/7.3.0 on a NanoPi M3 (Samsung S5P6818 Octa-Core Cortex-A53) these are my results:

variant 0: 28.6 H/s variant 1: 28.4 H/s variant 2: 27.2 H/s variant R: 14.9 H/s

SChernykh commented 5 years ago

ARM code doesn't have JIT code generator, I didn't think someone would actually use ARM processors for mining.

osensei commented 5 years ago

I don't mine on it, I was just testing it for fun. Maybe there are some people out there actually mining on them. I just thought I would post my results in case you weren't aware of the performance hit. Thanks for all your work btw :)

System is a HP DL580-G7 Server with four Xeon E7-8837 processors running Ubuntu 16.04

xmr-stak 2.10.0 56d2770

32 threads, 8 threads per processor, on each processor four double threads and four single threads

V8 - 1500.6 H/s R - 1498.8 H/s

So exactly the same for cryptonight_v8 and cryptonight_r

ARM definitely takes a major hit - xmrig no longer builds for iphone 6s and later (arm64 / aarch64) starting with v2.13.0, so I changed some of the build files to get a working binary. The new binaries run, but with about 75% reduced hashrate - i.e., from ~58.9 H/s to ~14.7 H/s!!

On RPi 3B running 64bit Ubuntu, the hashrate reduced from ~7.3 H/s to ~3.0 H/s.

So, an all around major reduction in ARM devices.

Any progress on Dual-Opteron 6276? CN/0 and CN/1 were around 1050kH/s. CN/2 was a knockout with 740kH/s. Will CN/R get it back to >1000kH/s?

SChernykh commented 5 years ago

@resistor4u ARM doesn't have JIT compiler for cn/r, this is why it's slower now. But it's possible to implement. @gvgit Most likely not, but cn/r was a bit faster than cn/2 last time I tested it.
