GPU solo mining on reset report

Almost base diff = 0.02.  I am shutting down my GPU solo mining, no longer profitable.
Almost 6 hours into GPU solo mining,  Nvidia GTX 1050 card,  1.78 million NENG mined  and confirmed into NENG wallet.   My GPU will be back on NENG mining on next reset.

Spike Block Mined, 51% Security Mechanism triggered

Spike block is mined:

A 51% security mechanizm triggered. CPU miners will likely to dominate mining now. This also means that reset is coming soon.

Alert for GPU solo miners, reset in 12 hours

Latest projection for next reset in 12 hours from here. Or 5:00 am U.S. eastern time there will be a reset to close to zero base diff . In 12 hours, GPU solo miners on NENG can mine millions of NENG within one day.

GPU solo mining reset morning report
I got in early in the morning several hours before reset on my GPU. Wake up, now see 288 block mined in ccminer, in wallet 2.23 million NENG mined for 10 hours running. At beginning hours were nothing, then NENG rain on my Nvidia GTX 1050 solo mining setup(edited).

This is first time my GPU got in before reset starts. Usually I was several minutes to 1 hour missing at beginning.

Updated Best Practice for Futurebit Moonlander2 USB ASIC on solo mining mode
- Problems for USB ASIC solo mining on NewEnglandcoin (NENG)
- Root Cause for ALL POOL DEAD error
- Workaround: rotate solo mining on two full nodes
- Alternative: rotate on 1 solo mining one full node + 1 mining pool
- Experimental feature to boost reward on reset

This script is for linux server only. However, windows 10 solo mining on USB ASIC futurebit moonlander2 can use similar method as above on two rotating nodes to achieve similar results.

why Android phone NENG cheetah mining reward Dropped Severely
I think I figured out why Android phone NENG cheetah mining reward has gone down a lot, to the level even that 4 core android is even poorer than 1 cpu old PC.

Here is why. At beginning of NENG cheetah CPU mining months ago, average cheetah block mined by CPU was 2 minutes, or 120 seconds by one or two cpu miner full node. Now there are 30 to 40 nodes on Cheetah_Cpuminer of NENG full node mining NENG. Now the average cheetah block is divided by 30, 120 seconds becomes 4 seconds per cheetah block in average.

Android phone ARM CPU is slow, it has problem to sync. Even if it has 8 CPU threads in UserLand linux, but slow to start. --interval recommended for phone is 10 at smallest. This means that by the time Android phone no matter how much cores it has, by the time phone start to mine, using more threads, the cheetah block was mined already by other PC or Mac. Android phone in this case is severely disadvantaged because of slow start and slow CPU nature of arm on 1 core basis.

Android mining scaling fix v1.5.x is on testnet code base

testnet code change on  android phone scaling hard fork fix is coded at github branch:  "v1.5.x_cheetahscaling"
Cheetah diff now is separated out from reset diff and now set at cheetah diff= 0.0078.  All feedback on cheetah cpu mining on testnet is welcomed to dev team.

Once this testnet testing is passed, a formal pdf proposal for NENG v1.5.x hard fork will be provided to NENG community for this new hard fork.

1st try of testnet on new cheetah diff

arm64 binary compiled for new testnet code.

First try of overnight run on testnet on v1.5.x on cheetah diff = 0.0078,  4 core android plus 3 CPU linux in virtualbox of windows 10.  Both are on cheetah cpuminer,  no GPU, no ASIC. Just see how both cpu miner will perform on this v1.5.x new diff on testnet.

[honglu69]

Run for almost 1 hour,  does not look good.  testnet print out hashrate.  3 CPU  linux:

Code:

hlu@mx:~/.newenglandcoin/testnet3
$ grep  hashmeter debug.log 
2020-11-25 02:30:14 hashmeter      4 khash/s
2020-11-25 03:00:16 hashmeter      4 khash/s
2020-11-25 03:15:44 hashmeter      5 khash/s
hlu@mx:~/.newenglandcoin/testnet3
4 core android phone:
hlu@localhost:~/.newenglandcoin/testnet3$ grep  hashmeter debug.log 
2020-11-25 02:30:52 hashmeter      4 khash/s
2020-11-25 03:00:56 hashmeter      9 khash/s
2020-11-25 03:17:20 hashmeter      0 khash/s
2020-11-25 03:22:36 hashmeter      5 khash/s
hlu@localhost:~/.newenglandcoin/testnet3$

each has about 5 kh/s.  Combined about 10kh/s.  1 GPU like Nvidia GTX 1050 has about 220 kh/s.  The cheetah diff appear to be too high at 0.0078

Base diff reset to low level, boom for solo GPU/USB ASIC miners

Base diff reset to low level earlier today, another boom for solo GPU/USB ASIC miners.

Just started my GPU solo mining, Nvidia GTX 1050, NENG rains comes on ccminer:

Testnet 1st Try v1.5.x Android Mining Scaling Results

Here are the results on the last overnight run.

Miners: two Cheetah cpu miners with cheetah_cpuminer software, no ASIC, no GPU, testnet only.
1 PC miner: 3 cpus in a linux within virtualbox of window 10.

1 android phone miner: 4 core android phone, --interval 10 --cpu 6 flag, using 6 cpu threads out of total 8 cpu threads in UserLand linux.

Total mining time: 14 hours
Total blocks mined: 18 blocks.
Average block time per block 46.7 minutes per block, or 44.7 minutes per block excluding the 2 minutes wait time. Cheetah_Cpuminer does not mine until after two minutes of waiting.

3 cpu linux mined 8 blocks or 44% of total blocks
Android phone mined 10 blocks or 56% of total blocks

Conclusion

v1.5.x hard fork separating cheetah diff from reset diff is success on testnet. The android phone outperformed three CPU linux while currently the same android phone under-perform 1 cpu old linux. This shows that the method works as solution for scaling up android phone mining as hardfork upgrade.

Average of 45 minutes per cheetah block on 1 phone + 1 PC setup may be too slow for actual v1.5.x code base. This needs to be worked on for more testing later on. The theory and method is tested well and proven to be working.

Another Testnet Testing on current cheetah diff

Under current cheetah diff = 0.000244, testnet,  no GPU,  no ASIC

3 cpu linux vs 4 core android phone

Total of 18 blocks mined in 79 minutes

3 cpu linux:  14 blocks mined or 78% of total
4 core Android phone (interval 10 cpu 6):  4 blocks or 22%

The android phone appears to not able to multi-thread into 6 cores even though on --cpu 6 mode on cheetah. Most of time android phone only
uses about 2 - 3 cpus load.  This explains the poor % results on this 18 blocks testing.

Average time per block: 4.39 minutes per block or 2.39 minutes per block excluding two minutes cheetah_cpuminer wait time.

Base diff reset to 0.0009, boom for GPU/USB ASIC solo miners.

Not sure why and how this reset is so close to last one. Just saw a spike block mined earlier today, which could be the reason.

ill tell you why... its because you trigger them/. you dont like anyone else getting te coin and when there is more hash on there than you can compete with... oh looky what happens.. it gets triggered.  you have done nothing for this coin except rip of the users or it and line your own pockets. ..

if this is not the case... show me the code and were it isnt being activated by you then

and explain to me how i have 48 cores... solo mining.. each using a different address... i have the cheetah miner running on 24 different instances... i have 3 moonlanders... solomining...... but i still only hit a block 1 out 200......... and let me guess... you hitting every block
