Hi,

I have installed jtoomim p2pool, rented a miner with 1.2Th/s on miningrigrental.
I am getting an error about very high difficulty from the web interface of the mningrigrental:

Code:

High Worker Difficulty
One or more workers on this rig has been assigned a share/worker difficulty by your pool that is too high. Hashrate performance issues may occur.
The OPTIMAL Difficulty range for this rig is 1,048 - 6,286
Please either adjust your worker settings at your pool, or change pools if you are unable to do this at your current pool. Thanks!

On my pool:

Code:

Pool web interface:

How does p2pool adjust the difficulty? What did I miss?
How can I lower the difficulty?
I have tried to pass "d=12000" as a password for the miner, but I do not think it made any difference.
Same miner works fine on p2pool.org:9332

What do I do wrong?

Thanks!

p2pool.org website is not showing full and updated information, for example, in the "miner dashboard" page, it shows only expected payout.

same thing for "P2Pool Node Data" , "Recent Blocks", "Active Miners (node)", and "Recent Shares (node)"

Anyone facing the same issue?

I’m on vacation (which is when things typically break), but everything looks ok from here, can you elaborate?

I've seen this issue too, and have not yet been able to figure out the cause. I didn't realize it was affecting all nodes on the network at the same time. Thanks for pointing that out, it's useful information.

These dips appears only if the rigs are connected to the nodes via the Internet.
If you connect the rig to the nodes in the local network they are not present.
In the screenshot #3 I marked it.

If you're running one of the nodes that does not have this issue (siberia.mine.nu:9338 and p2p-spb.xyz:9338) could you please contact me and let me know which version of bitcoind and which version of p2pool you're using?

jtoomim, could you kindly create a new thread for your LTC and BCH P2Pool forks in Pools (Altcoins)? I'd like to keep the current P2Pool thread Bitcoin-only.

A very bad idea. The source code is the same. All changes apply to any coins.

Why write the same thing in two topics? The subject cannot be split.

They are no different from the BTC fork. I see no reason to separate them.
Solutions found in the BCH and LTC forks will also help in the work of BTC p2pool

Yes good idea as this move would give P2P more exposure

My node also does this and I would love a fix for it. It sometimes causes a lot a asic HW errors when this happens. I'm using jtoomim 1mb_segwit 15.0-93-gb190c56-dirty
My guess is the miners are waiting for new work and stop hashing.

Hello everybody.
Can someone help solve this problem?

Dips in the chart at the same time.
Nothing important or is it a problem?
Personally, I tried the source versions from jtoomim and from Sawa.
Connecting the server to Internet through NAT or without it.
Bitcoin ABC version 0.16.1, 0.16.2 and 0.16.3
But!
On these nodes, there are no such dips on the graphs.

What is the reason? The difference in the hardware?
I'm so sorry my english isn't good.

looking at the nodes' scanner page, is there anything can tell us about CPU speed of a node?

Not really, no.

Quote from: moharni on February 12, 2018, 12:13:15 PM

It could be "GBTL =Get Block Template Latency," but I do not know what dose it mean. any idea?

GBTL is the amount of time that it takes for p2pool to get a response back from bitcoind when it asks for a new block template (i.e. a new batch of transactions). It is a poor indicator of CPU performance. It mostly just reflects block size. If the CPU is way too slow for p2pool, then this number will climb to 200 ms or longer (possibly even several seconds), but if the CPU is just a bit too slow, it won't show much at all.

Quote

But also, it is important to connect to a node that has small Latency (according to p2pool in this page: http://p2pool.org/learn/start.php)

That was written many years ago, back when block sizes were under 100 kB, long before p2pool started to show the CPU performance bottleneck.

that make sense, thanks jtoomim for the clarification

3) Is there video tutorial for beginner like me showing how to create a local node?

For example I do not know how to "run bitcoin with the RPC interface enabled" and how to"Run a miner daemon"

thanks

Good Question, Im surprised that no one has made a youtube video showing step by step for noobies like me!
I have access to a large scale network with hundreds of VM's if I knew how I'd create one, however I don't think it really benefits us anymore than what is available now, just need more people joining the current ones for better hashrates.

I agree, the pool needs more hash rate. But also, it is important to connect to a node that has small Latency (according to p2pool in this page: http://p2pool.org/learn/start.php). so is my case few node that I can mine with efficiently

2) I connected to someone's node (because I do not know how to create one) that has an average ping time of 75 ms, is this good?

75 ms is fine. The network latency to the node is a lot less important than the CPU speed of the node. A node with a slow CPU might take 3000 ms to hand out new work to your workers, whereas a node with a fast CPU might only take 500 ms. Whether you're adding 1 ms or 200 ms of network latency to that is nearly (but not quite) irrelevant.

looking at the nodes' scanner page, is there anything can tell us about CPU speed of a node?

I think you mean hashrate, and yes this is JT's currently:
Local rate: 58.1TH/s (2.1% DOA) Expected time to share: 2.1 minutes
http://ml.toom.im:9332/static/

Not the hashrate, jtoomim said CPU speed of the node is more important than network latency, So I was wondering if the scanner page provide such information. It could be "GBTL =Get Block Template Latency," but I do not know what dose it mean. any idea?

1) Why the average days to find a block in the past 6 months is 30 days while it used to be 5 days?

Because p2pool has not gained as much hashrate as the rest of the Bitcoin network. In other words, p2pool has relatively less hashrate than it used to.
