Hi, just switched 9 rigs to DSTM 0.5.8, using ethos 1.2.9.  I have a question regarding CPU Usage and was wondering if anyone has found and solution for this, here's the details

Rigs 6/7/8/9- Biostar TB250-BTCPRO/i3 7100 3.9ghz/120GB SSD/8GB RAM/12GPUs x Gigabyte 1070 Windforce OC
Rigs 10/11/12/13- ASROCK H110 Pro BTC/i3 7100 3.9ghz/120GB SSD/8GB RAM/13GPUs x Palit 1070 Super Jetstream
Rigs 14- Biostar TB250-BTCPRO/i3 7100 3.9ghz/120GB SSD/8GB RAM/12GPUs X Palit 1070ti Super Jetstream

DSTM miner program CPU load
Rigs 6/8/9 - 60% to 70%
Rig 7 - 30% to 35%
Rigs 10/11/12/13 - 65% to 75%
Rig 14 - 60% to 70%

All of the run of similar OC's and Power settings, I have been trying to figure out why the CPU usage Load on all these rigs are high except for Rig 7.  Has anyone have similar issues?

This might be the effect of CPU frequency scaling - especially since rigs 6/7/8/9 have same hardware. It's optimal (optimal with respect to power cosumption) for the cpu to reduce it's clocks as much as possible. You'll see a higher cpu utilization ofc if the cpu is running on low clocks. Try to disable CPU frequency scaling / set it to performance mode to get reliable data.

SOLVED! Thanks DSTM, tried to get help from ethos chat didn't get a clear answer

Window pops up a box?

I have never seen error "zm is stop working".

When my rigs crash they eject the GPUs or "connection to GPU lost.  Few cases where the whole thing shuts down.

You can't auto restart.  I got tired of it and let it rain.

Normal windows software doesn't work on windows server, especially 2008.

No drivers or support for any pro hardware.

Open Solaris is a better choice.  It's very stable and supports anything out of the box.

I have a workstation for video editing w 2 Xeons and 4 GPUs running on opensolaris.

BeOS is decent too.  The fastest I've ever used.  Still insanely fast 22 years later on my raspberry pi.

Does the recent Meltdown and Spectre OS patches affect the DSTM Miner's performance?
Has anybody done any before/after benchmarks?

From what, I read the recent Meltdown patch (KPTI) affects any programs that call the Kernel frequently such as netwoking, SSD disk access and CUDA memory copy operations from host to GPU.

How often does the DSTM Miner call the Kernel, anyway ?

I'm looking into this on both Operating-Systems. Not all OS-patches are finished currently... so yes, I'm aware of the of the increased systemcall time.

Does the dstm miner perform the Blake2b hash on the CPU and transfer the results to the GPU by calling the CUDA driver and the Kernel each time ?
If "yes" then it can be affected by the increased systemcall time due to the OZ Meltdown patches.

As far I know dstm miner only mines ZEC and can't dual mine unless you use a program like Awesome miner . I don't think the Meltdown patch will affect it ... but CM eth dual miner possible could sense it can dual mine Blake2b coin types. Ofc i don't know shit lol .....I understand what you mean !!! .... that's just a example or answer to a problem that might happen that's not limited to one coin .  i just wanted to add to it ........

That does not make sense!
Mining ZEC requires calculating a lot of Blake2b hashes for the Equihash algorithm.

You don't realize that article also applies to Windows 10, do you?

It does not start, it does not work completely, or it will not apply your boost to Core clocks?

If it does not apply only core clock, try to run Google Chrome along with DSTM miner and check if it works now.

So in Windows 10 this will keep it running?.   Perhaps dstm can add that to the compiled .exe so it won't fail overnight?  (I'll add it and check to see if it works)  thanks

use this script ( completly open source and free) by Acrefawn. It will take care of your rigs automatically, restart at set intervals or if errors happen. It's pretty great.
If you use it and it's helpful remember to support the dev after you tested it thoroughly.

Awesome this is one of the main troubles I face, and it is usually fixed with the old turn it off and on again. I'll test it out and see how it works

[ohfme]

I have it crashing within a day or so using the latest version. zm.exe has stopped working. Anyone figure a fix for this?

hi DSTM

please help me.

with reference to two rigs of mine that do over 3000 sols each.  

almost every morning when i wake up i notice no hashrate on pool monitor for these two rigs.  i then check miner and see  -  
connection closed by server   r 0
reconnecting


what do i do ?
i have done much troubleshooting with no luck.


regards



note:  i have other rigs under 3000sols on the same network that dont do this

[BansheeHero]

do you mean difficulty should be mapped to a smaller range such that it's easier to read? Float is a datatype representing real numbers it's not related to the radix/base that's used for representation.

What I mean is that pools expect difficulty configuration as a number, so even I know where my performance sweet spot is - I cannot just paste it as a hint to the pool.
I am not sure if that is possible, but it would be appreciated.

- Current log makes little sense without further tools. (I would appreciate more details)

What details are you missing? And how is it related to tools you would not need otherwise?

The idea of logging change is to make it easier to spot problems. The log right now has the information you need, it is just clumped together.
For example I switched to mining pool hub and performance dropped 5-10% - I used python to split the information and found out they are seemingly randomly changing difficulty back to 0001....
I checked the shares and found out the coin switching is not nicely implemented by the pool.
Other card had performance problems due to fan not scaling (For some reason the fan speed was not scaled on temperature in 2D mode).
 - Here might be a good innovation. If you can read PerfCap Reason and accordingly to it would be better rather than temperature.
 - I suspect targeting a temperature will be a good workaround
Now I am trying to find sweet spots for Sol/W, because going as fast as possible is not always the best efficiency.

Anyway I am looking forward to new versions, but I am sticking with 0.5.7. Performance on 0.5.8 is worse for me CPU wise.

Now that's is a very useful information. If there are any regressions between the versions - pls report them - I can't fix them otherwise and they might appear in later versions too. How much did the cpu load increase for you?

Since you took the time to respond, I took the time to replicate my original problem.
Unfortunately I was not able to. I am now running at 0.5.8

Make sure you have OC enabled in 2D mode. Miner does not trigger rendering anything. I am on MSI Afterburner and it works.

note:  i have other rigs under 3000sols on the same network that dont do this

look for the connection it tries to open, perhaps it will help to know what is the miner connecting to. (My suspicion is that miner is trying to connect to something that is no longer responding)
In windows you can use install PSTools from sysinternals and use "Process Explorer" for convenience.
In linux netstat should be enough.

Mining ZEC requires calculating a lot of Blake2b hashes for the Equihash algorithm.

Correct me if I am wrong, but increasing lag between CPU and GPU would only increase the demand on memory on the GPU. The impact on average amount of solutions should not be impacted by it.
On a unrelated note - is it normal that the  miner takes so little GPU memory? (<500MB for me)

Don't count shares if you don't know their difficulty (value), count total Sol/s. I guess your pool show somewhere total hashrate of your workers, and that matters

Soooo... if I have more hashpower am I getting more difficult shares or what? :S

Maybe (why not), but they will have higher value of course.

Try mining ZEC on Flypool, there is fixed difficulty, accurate hashrate reporting, nice graphs, so you can easily compare if your two cards mine more than just one. But you should let it run for at least 24h to get accurate average hashrate.

This based on luck. There is a guarantee you will find a share, but the amount of hashes it takes changes. Pools will report higher hash rate due to this. It is still ok to use pool hashrate.
Difficulty is used to balance workload. Higher difficulty will result in miner working in longer "cycles" which is beneficial to faster hardware.
Average solutions per second are the measurement of how your miner performs. Note that the reliance is always on the miner. That is why I am using pools as well.

2% fee on the miner and another % on the pool .. .cmon here..

Miner fee and Pool fee are unrelated as for the amounts it is 2% of my hashing power and 0.9% from the pool for my payment.

Hello guys!
Want to remind to all of you, that if somebody has any problems with stability of EWBF, DSTM, BMINER, CLAYMORE, CC miners or needs some extra control over your rigs please read carefully my message below.

I want to introduce you a script, which can solve most of your problems. It is a result of half a year hard work with my beta testers. Now it is clean of any bugs and ready to be introduced for the wide mining community.

1) https://bitcointalk.org/index.php?topic=2071108.0
2) https://forum.z.cash/t/cmd-equihash-miner-autorun-autorestart-watchdog-for-ewbf-claymore-dstm/20640

It will definetely reduce your valuable time spent near your rigs, because this script will do all the work for you. Just start it and forget about your rigs, relax or do anything else. In case of any problem this script will restart your miner, or the rig, if necessary. It will notify you by Telegramm message about all problems and corrective actions taken. It is open source code (CMD/BAT, not an .exe or something like this), so anyone can check throug the code if needed.
Enjoy your life, let the script to monitor your rigs for you.
