Performance and portability testing

[tevador]

Please post:

1. Your CPU, RAM parameters, operating system and compiler (if you compiled yourself).
2. Verification mode results.
3. Mining mode results (optional).

Precompiled binaries are available for Windows 64-bit and Ubuntu/Debian x86-64. Download the latest release here: https://github.com/tevador/RandomX/releases

Verification mode

Run as:

randomx --verify --softAes

• If your CPU is from the x86_64 family, add the --jit option to get 2-3 times faster verification.
• If you have a recent x86 CPU which supports AES-NI, you may omit the --softAes option to get a small increase in performance.
• If your system supports large pages, you can add --largePages option to get a small increase in performance.

Mining mode

Mining mode is currently only supported on 64-bit x86 CPUs. Requires at least 2.25 GiB of RAM. Run as:

randomx --mine --init Q --threads T --nonces N

• Select Q (number of initialization threads) equal to the number of hardware threads of your CPU.
• Find T (number of mining threads) which produces the highest hashrate. Starting point should be 1 thread per 2 MB of L3 cache, but some CPUs can benefit from running more threads, while some CPUs cannot run more than 1 thread per core efficiently depending on other factors such as L1/L2 cache sizes.
• Select N (number of nonces) equal to 10000, 100000 or 1000000 depending on the performance of your system. Aim for at least a 60-second mining period for accurate results.
• If your CPU doesn't support AES-NI, you have to add the --softAes option. Your mining performance will be about 40% lower.
• If your system supports large pages, you can add --largePages option to get a significant increase in performance (up to 25%).
• If you have a NUMA system, run one instance of RandomX per NUMA node.

I'm a bit overwhelmed with work at the moment, but I can get ARM AES working after my next conference is over in a couple weeks. Or someone else can beat me to it if they like.

Try mining mode with only 10 threads. It might run faster than 12 threads because of L2 cache size.

[klp18]

You mean L3? It is 25Mb per CPU (plus 2.5Mb L2). So 12 threads should be ok.

[tevador]

OK. Someone tested an 8 core Xeon with 20 MB of cache in https://github.com/tevador/RandomX/issues/22 and got better performance with 8 threads than 10. So your case is different I guess. In any case, since your system has NUMA, you should run 2 instances of RandomX (one for each CPU) for a total of ~7000 H/s.

I had to increase swap on the last one just to get it to mine. Is it going to require 8 GB of ram even if the box is just GPU mining? I mean, I'm definitely not pro GPU focused mining, but making every rig have a minimum of 8GB .... basically GPU miners try to get the things that run the GPUs as cheap as possible. Check the octominer. This thing maxes out at 8 GB ram. grumble grumble.

Can you please do:

g++ -maes -march=native -O3 -DTRACE -c src/main.cpp -o obj/main.o
make
bin/randomx --verify --softAes

and pastebin the result?

And here's where I grumble about this 4 GB dataset again.

Even if those CPUs had enough RAM, I'm estimating the following hashrates:

• AMD C-50 around 50 H/s at best (only 512 KiB of cache)
• Intel Celeron G3900 around 350 H/s
• Intel Celeron 3855U (Octominer) around 200 H/s (just 1.6 GHz without turbo)

Perhaps the Celeron G3900 would be worth it if you could find a cheap 4 GB stick to add to the system. But all these CPUs will have a very low performance per watt. My laptop can do ~1670 H/s at 30 W, so probably 5-10x the efficiency of these machines.

Trying to mine using the swap file is a pointless effort. If you insist to mine on a low-end system, you can mine in verification mode and at least get 5-25 H/s using just 256 MB of RAM.

I am sorry for that. Can you remove it please? It do not belong here, My mistake. I've never been here

@kdovijak AFAIK there is no such CPU and also your result doesn't match any version of RandomX. Can you please fix your comment and include the whole command line?

@JustFranz Try running memtest86. RandomX definitely cannot cause BSOD. It looks like defective memory.

[JustFranz]

Just finsished memtest86, 4 passes 0 errors. My BIOS is latest for mobo. My ram is in 4x4 GB configuration. Windows is up to date. Correction to RAM speed 1866 MHz 11-11-11-32

Just tested if BSOD was fluke, its reproducible 2/2.

Tried again in safe mode to rule out anything with windows, BSOD

have not used linux in my life (technically a lie), but going to give it a shot. What is a good USB bootable version?

[tevador]

What is a good USB bootable version?

Ubuntu 18.04 LTS.

The cause of the BSOD can be either:

• faulty hardware
• bug in a driver
• bug in the Windows kernel (unlikely)

Large pages is failing for some reason, I was under the impression that it was enabled by default for linux. What is the command to enter into terminal to properly enable it?

https://github.com/fireice-uk/xmr-stak/blob/master/doc/FAQ.md#error-memory-alloc-failed-mmap-failed

note that RandomX will require larger numbers than xmr-stak (2304 for vm.nr_hugepages and 4718592 for ulimit -l should be enough).

@seizahub you should try running two mining processes at once with 8 threads each, one process on each numa node.

[tevador]

I have pushed a new release which fixes some portability issues of the interpreter.

No impact on performance.

I found one case when endianness was not properly handled. Could you retest latest master on big endian?

If the result still doesn't match, please run

./randomx --genAsm --nonces 42

and compare the output with file src/program.inc. It should be the same code.

I ran a longer verification test (~40 hours) on Raspberry Pi 3 (ARMv7+Neon). Result matches x86.
