Plotting and Mining on Amazon Cloud Drive
-
@machasm Interesting, that you use the online chat, have been making a phone call but will try chat.
What are your stats. TB, Download speed, Read Time for the full plot etc? What do you get in the way of breaks in the Download?

@RichBC
Reading a 5.8TB plot at 9.53Mb/s takes 153 secs on a T2.micro instance. (don't really have a fast enough connection at home to mine remotely).
Sometimes, for no reason that I can make out, the downloads will slow significantly with occasional read errors.
I don't think that this is down to the T2 instance but probably down to the ACD download speed being throttled at some point (don't know why) as I have another T2 instance which exhibits the same problem at the same time.
Its pretty hard to figure out what is going on with so many variables!
Using the chat bypasses all the verification process as you initiate the chat once you are logged in.

@machasm With that TB & Download speed you must get some reasonable breaks in downloading, so disappointing that you are getting locked. Which Miner are you using? I am on Blago at the Moment and so far no read errors.
Here are my Break between Blocks for the last Blocks, there have been some slow ones.
0,0,0,0,0,2m,10s,0,3m,0,30s,0,0,0
The phone call is done on a call back, which is instant, so also no verification
Spoke too soon just had a couple of error ReadFile
Rich
Just had a 7min 21sec Deadline thought I was going to win the Block, but went to 5min 28 sec......
-
@RichBC
Yep using Blago here too.
The last three blocks were all within a minute of each other which means the plots didn't finish reading.
Most of the reads take between two to three minutes on 5-6 TB so as long as the block takes longer than that to solve then I get a portion of the share.
Only problem that I can see is if you get a short deadline (say around 30-40secs) but it is at the end of the plot read (about 120Secs from start) not sure what would happen here?
Would the DL be ignored or does it still count?
Meant to ask also which pool are you using?
-
@machasm In terms of getting a share all that matters is have you submitted a Deadline, where it is in the plots is irrelevant. If so you will get a share proportional to your Deadline v all the other Deadlines on the Pool. That then builds in your Historic Share and will become "real" when a Block is hit by the Pool.
Which Pool are you on? I am on pool.ccminer.net:8080 because that is where my main 80TB miner is at the moment, so I can keep an eye on them both. It is geared towards larger miners (deadlines < 24Hr) so I am only hitting occasional deadline, but this is testing so does not matter.

@RichBC
I have been having quite good payouts on pool.burstcoin.sk BUT they have had some server issues recently with it getting stuck on a block or worse, being unavailable altogether!
That said it is up and running now and I have three miners running there
BURST-H4NE-J5SQ-9FNZ-HMYTF
BURST-GGYR-VRZY-6BMT-ET5HQ
and
BURST-FBRW-6NKH-W3L6-5UXA5
Also forged a couple of blocks there!!
-
@machasm Have had a couple of Hours from Home and got a measure on how things are going, so have switched to the Free EC2 Instance for a comparison.
So it runs fine but immediately ran into the string of error Readfile. It is endless and you have to stop and restart the miner

RichOdd thing is that if I restart on the same Block I get the error again at the same 80% point in the file?
Rich
-
@RichBC
Yes I have had a couple of those. It is related to network performance I think.
You may find that this problem will dissappear and then reappear.
I can see that this is happening after restarting the miner as there is no way you are getting 57.32Mb/s from tha instance!!
What speed are you getting btw on the t2?
-
@machasm yes that snapshot was after a retry, so out of the cache. Don't no the speed yet, it stopped on the first block and then on the next block I immediately got the string of errors. Last time I tried the ec2 I had a lot more problems with this error. Back in a minute with more.
Had to disconnect and reconnect NetDrive to get the Miner to run without errors?
Initally I was getting 20Mb/s but seems at the moment to be throttled to 10Mb/s You can see the throttling here.
But a lot of errors needing a disconnection and re connection. so overall not looking very good...

@RichBC
Which OS have you opted for in the AWS instance?
-
@machasm Win Server 2008 R2 Datacenter
Have gone back to the Home PC for the moment which is Win 7 Ultimate
Here's the Home Transfer Graph, very flat topped, completely maxing and limited by my Download Bandwidth.

@RichBC
I am running 2012 R2 on my instances. Don't think it will make any difference though. Your home network speeds are comparable with what you are getting with the T2 instance. Only problem is that you need to leave your home PC running 24/7 so electricity costs come in to play. The T2 instance however is free!!
-
@machasm It runs 24/7 anyway, so no additional cost :-) Its not my main home which has terrible speed and very unreliable Internet, we are 4 Miles from the exchange, but I have put a remote PC at what will be the main Home later this year and fortunate to have a fibre cabinet 300Yds away.
I will run as I am and see how long it takes to get locked?

So I mined with the 16TB for some hours Yesterday, however later in the day everything ground to a halt on the Pool I was on.
Have moved to pool.burstmining.club this Morning and we are up and running again. Deadline here is much longer so am making more submissions. Let's see how it goes Today?
Rich

@RichBC
Hey Rich. Looks like the pool you were on is still stuck this morning! Shame, as I was thinking of hopping on to it too.
-
@machasm OK so far on pool.burstmining.club. I am hitting deadlines about 9 out of 10 Blocks and get through the plot about 50% of the time, so some breaks in the Download.
So although way off meeting the usual criteria for a read time ( 30 seconds) I think in the context of low cost Cloud Mining what I have at the moment is about balanced.
So that is to say 16TB with a 80Mb/s Download speed, 8 Minutes to read the Plots?
Rich
-
@RichBC Ok, found the size parameter in the .ini file too...I'll try that out.
@machasm Thx I will try rclone to do the uploading instead of NetDrive2 or the native ACD desktop app...Scripts got quite complicated with those because of the waiting for the cache to get purged.
Have you taken a look at the small Linode.com VPS offerings to do the mining (I'm not there yet) ?
They state 40Gbps Network In for 5 bucks a month ...
-
Everything was fine as reported for about 10 Hours yesterday then started getting these errors and the Download speed dropped right down.
Both readFile, and error opening. Tried restarting the miner and closing and reopening rdrive but no improvement. Checked the internet speed and my end and it was fine.
Eventually gave in and stopped Mining, restarted first thing this Morning and everything fine again for the last 5 Hours. So do not know if it's a time of day thing or if Amazon start throttling after some constant downloading?

@RichBC
I have found that there seems to be a point in time (normally evening here in the UK) when things slow down from ACD.
I have verified this problem running on two AWS instances an TWO ACD drives and it seams to happen on both at around the same time so maybe a global problem with ACD?
Also noted that on occasion the T2.mcro instance can grind to a very low speed but as soon as I change to another instance on the same cloud drive the speed picks back up. Could this be down to CPU cycles being throttled on the AWS instance perhaps?
-
@machasm OK could be the same problem, am in the UK as well. That log above is just before 7 Oclock, and it was still bad at 9 oclock.
