PS: I will have to hand over the KNL prototype in about 6 hours, I will take it out from working on the pool forefront and revisit manually the space where we had the Win-clients lapse. At that time, we hadn't the puzzle transaction hash160es in our .blf or balances files, so let's find out...

Rico,

What were the directory.io page numbers for the puzzle finds?

Would it be the hex divided by 128 to get the page number?

Answered my own question, haha.

Thanks,
Jude

...I have not made any cost/benefit evaluation...

Now I did. 96 GKeys effectively cost me 5.8 cent of my $70 budget.

I will spend $29 on that (about 48 TKeys) and leave the rest for... p2.16xlarge instances Wink

Sweet, thank you.

Also, I am right now throttling the AWS servers and renaming to let them start over and over again under a new id, else they'd probably totally destroy the top5.

I have more AWS credit which is valid only until end of this month, so I will probably have to start up some more. Eventually we may see a 100 MKeys/s. At least you get used to it. :-)

observe 6ac7b44b3c7f61c89a8a4fd0f7896376 climbing up the top30
It's a Knights Landing cluster prototype, that I can let run only for a couple of hours for this.

Do you know how much it costs in cycles on AWS?

All I know is, that I bought $1200 worth in AWS credit here @ bitcointalk (https://bitcointalksearch.org/topic/x-1567262) for $70 and I have not made any cost/benefit evaluation, because I am developing a project - not setting up a profitable business.

My AWS console says, I have "burned" $51 in AWS credit so far.

Hi,

all Go-generator operators, please be aware, that the pool will set the minimum client version requirement to 0.870 on Friday 21st.
This will effectively render the LBC clients using Go-generator backends defunct with the pool. You can still use them offline with manual intervals as you like, but the shares will not be accepted by the pool anymore.

Currently, the Go-generators account for less than 4% of the pool capacity and with even better generators than HRD-core on the horizon (*hint* *hint*) it's time to move on.

Of course your client-Id will remain in the pool db, and as promised your early adopter shares attached to that id will have a significant weight in a future reward concept. Oh - I will write about that and some other things soon.

I thought about setting that up in the stats, but you can make a good educated guess yourself quite easily.
In the block below, I added line numbers and the "Pool: xxx" (and removed the 'o' progress indicators)

If you look at the intervals your client gets and subtract the to-value in 1. from the from-value in 2., the to in 3. from "from" in 2. etc. etc.
and if you multiply these values with "1.048576" (which is 2^20/1000000) you get basically the MKeys the pool worked through on the forefront (i.e. auto-mode operation).

So you see in 1. the client represented a capacity of about 15.3% of the pool, in 2. about 11.9% and in 12. about 9.9%
This way you can also see - at least the tendency - if the pools performance accelerates or slows down.

Code:


 1. Ask for work... got blocks [44971058-44974897] (4026 Mkeys) Pool: 26341 MKeys
 2. Ask for work... got blocks [45000018-45003857] (4026 Mkeys) Pool: 33891 MKeys
 3. Ask for work... got blocks [45036178-45040017] (4026 Mkeys) Pool: 18439 MKeys
 4. Ask for work... got blocks [45057602-45061441] (4026 Mkeys) Pool: 21207 MKeys
 5. Ask for work... got blocks [45081666-45085505] (4026 Mkeys) etc.
 6. Ask for work... got blocks [45103938-45107777] (4026 Mkeys) etc.
 7. Ask for work... got blocks [45138754-45142593] (4026 Mkeys) yadda
 8. Ask for work... got blocks [45160242-45164081] (4026 Mkeys) yadda
 9. Ask for work... got blocks [45183346-45187185] (4026 Mkeys) won't
10. Ask for work... got blocks [45218930-45222769] (4026 Mkeys) compute 
11. Ask for work... got blocks [45241266-45245105] (4026 Mkeys) all that
12. Ask for work... got blocks [45280866-45284705] (4026 Mkeys) Pool: 40568 MKeys
13. Ask for work... got blocks [45323394-45327233] (4026 Mkeys)

In case you are bored and wanted to know "how much" of the current pools capacity your client does.
It's not exact, because it doesn't take the manual searches into account which may be in completely different intervals, but it's more exact than the "Pool Performance" number in stats, which is a 24h moving average.

Therefore with this method you may see more variance in the pools performance, as there may be a spike if a big client delivered several hours of work in between your deliveries. I added also an "Activity" column to the Top30, which is a "last seen xxx ago" for the clients.

Oh and one more thing: Don't be surprised, if Pool speed will now slowly raise to ~ 40 MKeys/s Grin

How to get and AWS EC2 t2.micro istance for free?

I'm not entirely sure - one day I had this email from Amazon saying I could get one.
I think it goes somehow like this: https://aws.amazon.com/free/

I did some small updates which now allow LBC to run on a gossamer AWS EC2 t2.micro instance:

a) pulsed operation - see http://lbc.cryptoguru.org:5000/man/user#pulsedops
b) memory friendly hexdigests while updating (from version 0.893 on)

I got this t2.micro instance for free for a whole year. It's the most flimsy piece of computing power I ever saw, so I felt challenged to make use of it for LBC.
You can get like 2.8 GKeys per day out of something like that. So next challenge will be to run LBC on my toaster. Roll Eyes

Code:

[ec2-user@ip-1x2-xxx-20-xx ~]$ ./LBC -c 1 -t 10 -delay 5400

Hashrate increase wow. up to 23.29 mkeys/s

Yes, we have some new active clients. Also, the LBC Appliance I mentioned yesterday is being used, so some clients have now 13x the ~~hashrate~~

keyrate.
Unfortunately the pool lost around 10 MKeys/s because of an accident of one of the clients...

Still people: remember these times. With GPU clients it will be like 3 digit MKeys/s at least.

I still see lots of Go-generators on Windows duly and diligently delivering blocks. I believe by now all Go-client operators are aware of the speed difference between the Go-client and HRD-core. One reasonable conclusion may be, that for a Windows user somehow installing Linux and on top of that LBC isn't just worth the effort.

I understand that and agree. Compared to executing some .msi, LBC installation was still PITA en large.

Good News Everyone! LBC installation on Windows just got a lot less PITA. You may even say it could be considered bearable now.
My definition of bearable:

You have to download about 1GB of data in 2-3 packages.
That and really only few clicks you have a completely installed "Jarvis" LBC (including blf file, xdelta3) ready to go.

Here's how:

Make sure your computer is 64bit and supports virtualization (which is enabled in the BIOS)
Download and install the VMware Player for Windows (~75MB): http://www.vmware.com/products/player/playerpro-evaluation.html
Download the LBC Appliance (~960MB): ftp://ftp.cryptoguru.org/LBC/appliance (*)
This appliance is - at the moment of this writing - an updated Arch-Linux 64bit, installed ready-to-run LBC Jarvis 0.886 - including a recent .blf, xdelta3, gcc
Only if you need something to unpack a .7z archive: http://www.7-zip.org/a/7z1604-x64.exe

1) Unpack the archlinux.7z, it will need around 2GB on disk.
2) Start VMware Player, choose the Archlinux Image, Press "Play"
3) I took the Arch Linux base from: http://www.osboxes.org/arch-linux/
   so Linux should boot and in the login you enter
   username: osboxes
   password: osboxes.org
4) You type

cd collider
./LBC -x

from there on, you do whatever you want. Wink

After giving it some more thought, I would like to revisit this:

Quote from: ryanc on October 12, 2016, 10:06:34 AM

Well, this result demonstrates that only the outputs of that puzzle transaction were searched by whoever did that, which only mildly surprises me.

The alleged mode of search of whoever did the search for the PKs in the puzzle transaction was discussed
in https://bitcointalksearch.org/topic/m.16348760 ff.
between you and donGeilo

We have found #45 (https://bitcointalksearch.org/topic/m.16430637), but have not yet found #46 (https://blockchain.info/address/1F3JRMWudBaj48EhwcHDdpeuy2jwACNxjP).

The fact, that we have found 1PVwqUXrD5phy6gWrqJUrhpsPiBkTnftGg in-between, which a) pre-dates the puzzle transaction, b) seems to be there before (in terms of key value) 1F3JRMWudBaj48EhwcHDdpeuy2jwACNxjP indicates, that whoever searched for the puzzle funds, did not perform a search such as both you and donGeilo assumed. Which - honestly - should take the mildness from your surprise.

Only explanation I have (which is consistent with the observations so far) , would be that the searches were performed backwards (i.e. for #46 starting at bit47, then decrementing PK values) and rest of the search space is skipped when puzzle transaction is found (starting again at bit48 for search of #47). IMHO this is the only way how 1PVwqUXrD5phy6gWrqJUrhpsPiBkTnftGg could have remained unseen in that search.

Alternative explanation could be that 1PVwqUXrD5phy6gWrqJUrhpsPiBkTnftGg was seen, but not bothered to touch. Not sure how probable that is.

Rico

But I think the addresses higher than 35 were searched by a modded vanitygen, in other words he searched exactly for these addresses and not for funds.
