Current Problem with Collatz [info]

Good at maths? Then why not figure on helping these projects - BURP, Citizen Science Grid, Collatz, Enigma, Gerasim, Moo! Wrapper, NFS, NumberFields, primaboinca, PrimeGrid, Sztaki, WEP+M2)

Current Problem with Collatz [info]

Post by chriscambridge » Mon Apr 02, 2018 1:14 pm

Just so everyone is aware an issue has been raised with Collatz, with some hosts completing tasks in around 5 seconds.

via: https://www.reddit.com/r/gridcoin/comme ... atz_hosts/

Response from Project Admin:
Project Down Until...

It seems a few people have come up with a way to game the system.
Until I figure out what damage they have done and how many thousands
of work units need to be re-issued, the daemons are shut down. You
should still be able to return any completed work units and they will
eventually be validated and credit given if valid, but no new work units
will be sent until new applications and server daemons have been developed.

Hi Chris

Thanks for the heads up.

One wonders WHY people do this...(yes I know they do it just for the credits)...but the project suffers if the work returned isn't "kosher" and as noted the original tasks have to be returned to the "available work" pile so that people crunching this project, for the projects benefit, can return a real result.

I really hope the admins of Collatz ban the perpetrators and publish who they are.

AND I hope they nullify any credits earned and we can then see which teams suddenly lose lots of credits - I really hope none of the UBT membership are involved.

regards
Tim

PS: The computer shown above is "crunching" !!

https://boinc.thesonntags.com/collatz/r ... e=4&appid=

In the last DAY this computer has "earned" 925,120,000 Collatz credits - that should make it easy to spot on BOINCstats !! Plus it has probably earned lots of GRC and Etherium tokens too !!

I totally agree.

In the above case, the host was a GRCPool member - however their account has now been blocked and none of the GRC will be issued to them.

So they have not only wasted everyone else's time, but also their own. Like you mentioned, this kind of issue is pretty easy to spot so I am not sure why they really bothered.

I think the most that could maybe be published is their IP and perhaps a GRC Wallet address; which may or may not be useful in tracking down who this/they are.

Hi Chris

It could be this/these "user(s)", grcpool.com-3, sitting at the top of the table":

https://boincstats.com/en/stats/86/user ... /bestxdays

and with these recent stats:

https://boincstats.com/en/stats/86/user/list/10/0/0

and these are the "hosts" earning the credits:

https://boincstats.com/en/stats/86/host ... /0/1584175

two of which seem to be earning the most !! (and both have same CPU's
Intel(R) Xeon(R) CPU E3-1230 v3 @ 3.30GHz 4(8) Windows 7 Professional x64 Edition, Service Pack 1, (06.01.7601.00) 925,120,000 925,120,000
Intel(R) Xeon(R) CPU E3-1230 v3 @ 3.30GHz 4(8) Windows 7 Professional x64 Edition, Service Pack 1, (06.01.7601.00) 922,240,000 922,240,000
I am purely GUESSING at the above as this seems to tie in with a user who has generated approx 900 million credits per day - in fact over the last couple of days it's been more like 1 billion credits per day...

I wouldn't worry too much as GRCPool admin is already on the case.

I'm not so worried about the GRC - more the problem is that the Collatz admins must now spend time on checking all the results from this scammer, nullifying them and then re-writing the app code to prevent this happening again.

So, thousands of Collatz crunchers will not get any new work for a time, until it is fixed. Plus the admins will need to spend time and money on developing the new app.

Maybe GRC can (should?) pay them for their time? as it is one of their "pool" users who has done this.

I hope they can get their IP address and block them.

I've been running a lot of Collatz and I've still got quite a few tasks waiting to run. Should I just leave everything as it is and wait for things to get sorted? I've re-enabled Primegrid to keep stuff available for my GPU when Collatz runs out.

Hi Jeff

Let them run....there's no issue with tasks sent out to genuine crunchers.

The issue will be that the Collatz admins will stop generating new work to be crunched, until they have re-developed the Collatz app that does the "donkey work".

But feel free to also allow tasks from other GPU projects such as PrimeGrid and Moo!

When a new Collatz app is available, you may be asked to delete the project from BOINC Manager and to then add it back again, as this will "force" a download of the new app. Also, make a back-up copy of your "app_config" file (in your Collatz directory) as you may find that gets deleted if you remove the project from BOINC Manager.

(It is possible that Collatz will automatically update the app, once they have fixed it...but that won't be known until they sort it out).

Hi Jeff,

Any work already sent out can be safely crunched and returned. there won't be any new work. to be ultra safe, you can pause any work that isn't near it's deadline yet just in case.

The problem is that until the admin has decided what work has actually been carried out then nothing returned is going to get validated so do the work, return the task and sometime in the future you'll get the credit for it.

I would imagine it's going to take a few days to sort out so you'll need a different project unless you have a LOT of work in your cache.

Hi Chris,

My understanding was that the owner of the hosts wouldn't be getting paid but their credit was still being counted? Doesn't this mean that all other members of Gridcoin crunching Collatz will be getting a relatively smaller payment than they should?

Part of a post from Brian:
From a pool perspective, the account responsible for the hosts is locked and will not payout anymore GRC into the owners Gridcoin wallet. The Gridcoin network and pool will continue to recognize the host credit until Collatz eliminates the statistics.

HI Mark,

What will happen is the host will still be allocated GRC due to RAC/MAG, however their account has now been frozen and no GRC will be issued to that wallet; indeed I am sure reverse transaction analysis is being done on that wallet address right now to try and find out who owns it.

Additionally I am guessing the IP, Mac address (of all related hosts), Wallet address (and related wallet addresses) will now be block/banned across Gridcoin.

Because of the massive numbers this host has done, yes it does mean everyone else who has crunched Collatz under Gridcoin will/has lost out quite substantially.

In terms of the fraudulent GRC; I guess there will probably be a GRCPool vote to determine what should happen to the frozen GRC. Either it will be "rained down" on other Collatz crunchers (as they are the ones who have lost out), or perhaps even sent to the admin of Collatz as a donation.

Hi all

I'd not heard much about the ongoing "fix" for this issue, so I took a look at the Collatz website.

It looks like their entire message board has been re-installed and all the previous messages (many years worth) have GONE !!

https://boinc.thesonntags.com/collatz/forum_index.php

It also looks like some the historical data on GPUs has vanished too (mainly Mac and Linux OS) !! (CPU info still seems to be there though).

https://boinc.thesonntags.com/collatz/gpu_list.php and

Also, due to the changes on the website, one needs to REMOVE the project from BOINC Manager and then select it from the "drop down" list and add it back again.

Needless to say *if* you are using an optimised CONFIG/XML file, make a copy of this FIRST, BEFORE you use BOINC Manager to remove the project, otherwise you may well lose said file(s).

If you do lose the file, then someone has already posted some info on the various options available for various GPUs, here:

https://boinc.thesonntags.com/collatz/f ... hp?id=8#69

So, be careful.

Hopefully, new Collatz tasks will be forthcoming soon...

regards
Tim
