SRBMiner Cryptonight AMD GPU Miner V1.9.3 - native algo switching

[666damien666]

Doktor,

i also have issue to report

goes like this
have 4 rigs, all 4 of them go from xmr stak to srbminer1.5.8
each rig 6x Vega 18.5.2
all 4 rigs run super stable with srbminer
one of the rigs i restart for some reason after like 2000 minutes of uptime
other 3 rigs run for like 3000-3500 minutes of uptime and then all crash at approximate the same time
the miner stopped saying  GPU hashrate 0, restarting miner, but miner could not restart, even by process kill or try to reset PC, it hangs in reset process. Only hard reset help

Why would all miners stop at same uptime?

Anyway, I reset all so can´t really say what happened or give any more details, but i will monitor this time and see if it happen again

Otherwise, i fell in love with your miner.

i have the same Problem, It got better with windows 1803 and amd driver 18.5.1

Any hashrate increase? Like for 1.5.8. when you didn´t say anything and my vegas hashed like 200 more per rig, what a nice surprise  

lol,no not this time. I am surprised too because i had a 0.2-0.3% hash increase on my 580 8g test card, so thats so low i did not want to mention it, but looks like its more than 0.2% on Vegas

Great update, good thinking on devfee pool settings, although a hardcoded fallback in code would still be beneficial.

Doktor, how costly is algo change? I'm working on a simple coin switching proxy (forked from a sebseb7's repository of cryptonote-proxy) which works well for same algo coins. The upside is there's no hasrate drop between changes as SRBMiner (or any other miner connected to it) just sees it as a new job.

That said, just as GPU's can run several different shaders, how hard would it be to change algo without a restart? Memory would be reserved for the one with the most mem requirements. It would be awesomely dandy if SRB could do this, it would support an extra json property to change algos in the job request.

There are hardcoded fallbacks, in case the site isn't reachable, those are used. I hope they will never be used
I know about that proxy, i like the idea , it can be very useful for coin switching on the fly.
Algo switching could be a problem, but a very easy and elegant way would be just to restart miner with the new config. It shouldn't take more than 15-20 sec if the user has cached files.

It's interesting that you ask this now, because i am in a phase of planning and working on a built-in coin switching (for same algo) in SRBminer based on profitability.

https://www.reddit.com/r/MoneroMining/comments/80vns0/announcement_moneroocean_pool_switches_to_multi/ - currently the only pool that multiswitch would be nice to have a miner like that. Thanks in advance!

Note: My vega hashdrop only happen because of 1-2 minutes disconnect from pool(this is normal since im using wireless/shared network).
I'll try lowering/disabling the Hashrate watchdog and report back.

Hey Doktor - any plans to support the new Masari algorithm (CN-Fast)?

See https://medium.com/@officialmasari/masari-launches-cn-fast-8d6a535a263f for details.

So you getting about 2200h now or more?

yeah dok im sticking to 1.5.8 my vegas got higher output compared to 1.5.9. https://www.reddit.com/r/havenprotocol/comments/8ohw6t/haven_v3_hardfork_coming_in_2_weeks/ - haven is also forking.

thanks for forking infos guys, srb is prepared for stellitev4, the other two ill have to check them out.

V1.5.9

- Added "max_difficulty" parameter in pools, if reached miner will reconnect to pool
- Better logging on miner crash
- Kernels are now built in Cache directory
- Probably fixed situation when miner crashes on pool switch
- Fixed .srb file creation on every miner run
- Hopefully reduced nicehash duplicate share errors
- Changed the way devfee pools are used

+ Now you can define a "max_difficulty" for every pool you have in pools config. Sometimes it happens that pool sends abnormally high difficulty, and miner can't find a share for a long time. In this case, by setting "max_difficulty", when ever pool difficulty is higher than the value you set, miner disconnects and reconnects to the pool.

+ There is now a Cache directory where the miner creates cached versions of OpenCL kernels

+ Some reported miner crash after multiple pool disconnect/reconnects , not able to log in etc.. I hope i found the cause of it and fixed it

+ Learned from the previous big mistake with devfee pools hardcoded in the miner, now miner gets the list of devfee pools from http://srbminer.com, so please allow/don't block it on your firewall

Cool stuff, dok. Starting to move to 1.5.9 now, 5 left remaining  .

EDIT:
All 8 rigs now running with 1.5.9, and looking good.

Thanks, dok!

1.5.8 shouldnt be faster than 1.5.9, cause nothing was changed that could impact speed. Placebo

unbelievable but true. my RX 550 2gb at 1.5.8 gave out stably 6590 hashes at setting 26/8/2, and on 1.5.9 neither as more than 6510 hashes

in this case, everything is not stable, or the cards do not start all at once, but only after a couple of reboots and after that in a couple of hours all the same 0 the hashes are shown and the reboot is going on. But on the other hand, the speed on version 1.5.8 strongly diverged by the indications on the pool, and 1.5.9 shows approximately equal values with the pool. So we stay on 1.5.9 I think 6500 with 13 RX 550 cards is a good result, the main thing is that there would be stability.
Thank you for the miner.

wow many thanks dok, will try now mining on nicehash with max_difficulty.

ok, and report is it working like it should
You can define max_difficulty for every pool like :

{"pool" : "lotsofcoinspool1", "wallet" : "", "password" : "x", "max_difficulty" : 150000},
{"pool" : "lotsofcoinspool2", "wallet" : "", "password" : "x", "max_difficulty" : 400000}

yes I already define max_difficulty, will monitoring for a while.
just to let you know I can confirm hash rate drop after reconnecting to pool for RX Vega.

Bro, in my case, after reconnecting, the hashrate was drop. But after waiting a few minutes, it's back normal.
May be you were too quick to observe?

Apologies, I misread..I got really excited but it's still better I suppose. Will try it out this weekend

Hashrate drop after pool change (disconnect/connect) is normal, but the hash should stabilize back. The problem is if it won't go back at all.
But i am curious is this somethings specific to 18.5.2 drivers ?

I thought there were my personal suspects, but checked again after reading this and yes, 1.5.8 is a little bit faster.
1.5.9:     "hashrate_total_30min": 7738
I've terminated it and run 1.5.8 with same configs:     "hashrate_total_30min": 7746,
maybe new nicehash features add a tiny lag to a mining process?
