[LOCKED] cpuminer-opt v3.12.3, open source optimized multi-algo CPU miner

[onedeveloper]

Sorry! I had not analyzed the full source for your miner 

What I have been doing for some time is testing the capabilities and limits of the miner. I have a simple laptop for my experiments. This is information from your miner:

• CPU: Intel(R) Core(TM) i5-4200U CPU @ 1.60GHz
• CPU features: SSE2 AES AVX AVX2

This CPU has only 3MB Level 3 cache, 2 cores and 2 threads per core (4 logical CPUs), so I have tried to maximize my mining capabilities under Windows 8.1. First, I mined XMR using 4 threads for a total of 55 to 60 H/s. After cheking the cache, I got the same value with only 2 threads. Finally, I have settled on using 1 thread at 25 H/s and the other 3 threads for mining Lyra2re2 at a combined total of 250-300 kH/s.

After thinking on what I've done, I can safely say that this is a viable Monero mining strategy for Ryzen 7 family of processors (8 cores / 16 threads, divided up into two CCXs of 4 cores / 8 threads each, and 8MB L3 cache each):

** Monero1.bat

Code:

REM ** USE THE FIRST CCX MAXIMIZING L3-CACHE
cpuminer-aes-avx2.exe -a cryptonight -t 4 --cpu-affinity 0x000F -o <POOL> -u <USER>-p <PASS>
PAUSE

** Monero2.bat

Code:

REM ** USE THE SECOND CCX MAXIMIZING L3-CACHE
cpuminer-aes-avx2.exe -a cryptonight -t 4 --cpu-affinity 0x0F00 -o <POOL> -u <USER>-p <PASS>
PAUSE

** OtherCoins.bat

Code:

REM ** USE THE REMAINING THREADS ON THE TWO CCXs DISREGARDING L3-CACHE
cpuminer-aes-avx2.exe -a <ALGO> -t 8 --cpu-affinity 0xF0F0 -o <POOL> -u <USER>-p <PASS>
PAUSE

** MineAll.bat

Code:

REM ** LAUNCH ALL MINERS AT ONCE
START Monero1.bat
START Monero2.bat
START OtherCoins.bat
PAUSE

Alternatively, you can use only 6 threads on the third file so you can use the remaining two threads to browse the web or do other tasks while mining in the background.

After thinking on what I've done, I can safely say that this is a viable Monero mining strategy for Ryzen 7 family of processors (8 cores / 16 threads, divided up into two CCXs of 4 cores / 8 threads each, and 8MB L3 cache each):

I think Ryzen 5 will be an excellent architecture for mining cryptonight due to it's L3 cache size and low price. The extra cores
of the R7 aren't needed for cryptonight. The more compute bound algos may do better with R7, but they also do better with GPU.

You are right. They can be entirely devoted to cryptonight and leave some free cores for other tasks at a reasonable price. The R.O.I. can be interesting to calculate once we have the first units to test. These will be the setups in this case:

• Ryzen 5 1400 will have 2 + 2 cores and 8 threads with 8MB L3 cache in total (4MB per CCX). This will allow to use "Monero1.bat" with "--cpu-affinity 0x03 -t 2" and "Monero2.bat" with "--cpu-affinity 0x30 -t 2". 4 threads are free to use in other tasks.
• Ryzen 5 1500X will have the same core and thread count as above, but with 16MB L3 cache, so it will use the "Monero1.bat" with "--cpu-affinity 0x0F -t 4" and "Monero2.bat" with "--cpu-affinity 0xF0 -t 4". The whole CPU will be mining Cryptonight.
• Ryzen 5 1600 will have 3 + 3 cores and 12 threads with 16MB L3 cache. They must use "Monero1.bat" with "--cpu-affinity 0x00F -t 4" and "Monero2.bat" with "--cpu-affinity 0xF00 -t 4" and still have 4 free threads to use elsewhere. This applies too to Ryzen 5 1600X CPU.

Looks like a problem with longpoll, try --no-longpoll.

edit: also try cpuminer-multi, if it works I can compare.

i have executed it with the --no-longpoll option, same error it seems, also tested with cpuminer-multi with and without --no-longpoll, same result:

Code:

to me it seems the rpc request method is "login" but this only works for pools

afaik one needs to connect to the daemon and use getblocktemplate?
atleast for the wallet there is no mining related method (https://getmonero.org/knowledge-base/developer-guides/wallet-rpc)
whereas the daemon rpc has a getblocktemplate method (https://getmonero.org/knowledge-base/developer-guides/daemon-rpc)

no matter which features is disable it always uses "login" method it seems (no-stratum, no-getwork, etc)

edit: after taking a look at this (https://github.com/sammy007/monero-stratum/blob/master/go-pool/rpc/rpc.go), im pretty sure for solo mining to work cpuminer(-opt) needs the getblocktemplate support for cryptonight coins integrated first

Yeah, no login method, but I don't think it's GBT related. I found an intereting bit of code

cpu-miner.c line 1264

Code:

        if(jsonrpc_2 && !have_stratum)
                ok = rpc2_workio_login(curl);
        while (ok)
        {

Notice no "else" clause so no login attempt here for other algos. You could try commenting out the login to see what happens.

I also looked at GBT code. I'm not sure now why I defaulted to disable GBT for RPC2. cpuminer-multi doesn't do it. You could try
commenting that out in ago-gate-api.c line 242.

I don't really expect either of these to fix it but it might eliminate some of the noise.

with the workio_login thing commented out i get:

rpc2_workio_login is called regardless of gbt or not. The login method isn't recongnized
and skipping it results in no authentication. With no working model and no real understanding of the
protocol I think I'm stuck.

damn, thanks for looking into it though, most profitable coins for cpu mining are either cryptonight or zoin/zcoin or something else/new

as a matter of fact i also tested zcoinclassic over this night but it seems their wallet contains the same bug hexxdev encountered in the imported changes from zcoin which my old wallet hadnt had: zcoin classics avg ttf is 0.6h with my hashrate but no block found over the last 7h, might be the same for zcoin itself (not tested)

Guys , anyone know a best pool for mining monero ? i want try with i7 5820k @ 4 ghz , and i5 6600 , im waiting ryzen 1700 .

Anyone ? .

Personally, I use nicehash, which mines XMR direct to your BTC account, and this cpuminer-opt client. This is what you need to use:

Code:

cpuminer-aes-avx2.exe -a cryptonight -o stratum+tcp://cryptonight.eu.nicehash.com:3355 -u <btc-wallet> -p x

Other interesting pool is MoneroPool:

Code:

cpuminer-aes-avx2.exe -a cryptonight -o stratum+tcp://monerol.com:3333 -u <monero-wallet>.<difficulty> -p x

Same bugs there, zcoin, zcoinc, but you could try gbt since the miner is now fixed.

i have done so, didnt work out sadly

Zcoin dev seems not to be so eager to fix it, and no 64bit release.

Did you try ccminer-tpruvot? It's coded differently and doesn't have the rpc2-login call in workio_thread.

just tried, it issues the following rpc method:

Code:

[2017-03-20 16:17:33] JSON protocol request:
{"method":"getwork","params":[],"id":0}

which results in

Code:

[2017-03-20 16:17:34] JSON decode failed(1): '[' or '{' expected near 'Requested'
[2017-03-20 16:17:34] Requested url is not found
[2017-03-20 16:17:34] get_work failed, retry after 30 seconds

seems ccminer is not compatible with solo mining as else it has to request the getblocktemplate method (?)
