Holy Sh!t - what happened to the puzzle transaction: https://blockchain.info/de/address/15K1YKJMiJ4fpesTVUcByoz334rHmknxmT

So whoever finds the next puzzle will be over half a bitcoin richer.

Hm. So it was the creator and indeed all rewards up to 160bit are now 10 times the BTC! Wow.
I think I will have to start some engines myself.  Wink

Ubuntu 17.04, this works for me:

Code:
# $ is shell/bash
# cpan> is cpan shell

$ sudo apt-get update
$ sudo apt-get install gcc xdelta3 make
$ sudo apt-get install nvidia-opencl-dev nvidia-opencl-icd-375 nvidia-modprobe clinfo
$ sudo systemctl reboot
$ clinfo
$ sudo cpan
cpan> install JSON OpenCL

$ mkdir collider; cd collider
$ wget https://lbc.cryptoguru.org/static/client/LBC
$ chmod a+x LBC
$ ./LBC -x


How do I install it for a p2.x16 amazon machine ?

Rico doenst answer to me  ... he is busy now


sudo apt install perl bzip2 xdelta3 libgmp-dev libssl-dev gcc make
cpan force install JSON
cpan force install LWP
cpan force install Net::SSLeay
sudo apt-get install libnet-ssleay-perl
sudo apt-get install libcrypt-ssleay-perl

What a super interesting project, I was quite a big contributor to BOIN, and I love playing with VanityGen, and now this, very exciting stuff, will get this installed and see how it goes, then report if I get any findings!

I don't know, I never installed LBC in a p2.x16 amazon machine.

Oh, looks like ftp.cryptoguru.org does not support passive ftp connections, so computers behind nat can not connect to it.

Same problem with ftp:

Code:

I am trying , but some problems and bugs in process

JSON not found - installing it
:/
and download link ftp is broken ;/


Parcial solution:

sudo apt install perl bzip2 xdelta3 libgmp-dev libssl-dev gcc make
cpan force install JSON
cpan force install LWP
cpan force install Net::SSLeay
sudo apt-get install libnet-ssleay-perl
sudo apt-get install libcrypt-ssleay-perl
sudo apt-get install LWP::Protocol::https
sudo apt-get install Parallel::ForkManager
sudo apt-get install Term::ReadKey
sudo apt install ocl-icd-opencl-dev

BUT , the problem now

ubuntu@ip:~/$ ./LBC
Will use 0 CPUs.
Benchmark info not found - benchmarking... failed to open bloom filter 'funds_h160.blf': No such file or directory
Generator validity check failed. Expected: 5, Got: 0

For all time was found 32 bts? This is for what time interval?
How is the production divided between the participants?

I like this project and I would love to help...

Someone mentioned pointing the pool to a different cryptocurrency, but what about something more like merged-mining?  Could the saved work be re-used on a different blockchain, like Bitcoin Cash for example?

Why not generate more complete search sequences (without the zeros at the begining)?  It might seem like it's taking longer, but it would be searching in a less obscure area of the search space.  And you wouldn't necessarily need to count by one's in a linear method, you may be able to write an subroutine to space it out without overlapping.  The odds of discovery might be about the same but it wouldn't be limited to the lower number space.

And I don't suppose the server side is open-source, but at least will the saved work be public domain?

I made a small modification to the server source:

Code:
    my $logtxt = "Query $id";                               # text to be logged

    if (!keys %{$entry}) {                                  # if there is no information yet about the client
        $logtxt .= " - not yet in DB.";                     # state so in the LOG
    }
    else {                                                  # here, we have client data
        delete $entry->{secret};                            # remove the (encrypted) password from the answer
        $entry->{gpuauth} = 1;                              # Happy Birthday LBC (From 2017-08-01 to 2017-09-01)
    }
    log_lbc($logtxt);                                       # LOG
    return  $json->encode($entry);                          # return our answer

What does this mean:

GPU authorized: yes
Benchmark info not found - benchmarking... done.
Your speed is roughly 3245154 keys/s per CPU core.
Ask for work... got blocks [5393996735-5394007934] (11744 Mkeys)
oooooooooo0 just got out of the pool with exit code: 255 and data:
3 just got out of the pool with exit code: 255 and data:
oooooooooooooooooo

Any other errors on screen? Most of the time this means the OpenCL failed to start

* no GPU found (probably not your case)
* worksize too big (not your case if you are not on Amazon)
* no memory left on GPU

In your case, it looks like

OCL error: CL_MEM_OBJECT_ALLOCATION_FAILURE (clEnqueueNDRangeKernel failed.)

edit: you sure you have up-to-date client/generators? I see you were last active 24 days ago, minimum client version is now 1.140, hopefully you have also a kardashev-generator too.

I installed everything new in a new directory.

It could be my distro install, I messed some shit up trying to install Boost.

Let me do a reinstall and try again.

Thanks,
Jude

Got past that and the odd missing blf error.   Looks like I'm good to continue.

Code:
Your speed is roughly 401519 keys/s per CPU core.

I see a user "___vh___" successfully asking for and delivering blocks.

May appear within a hour or two here: https://lbc.cryptoguru.org/stats/___vh___

As you probably found out already, the kardashev generators are unified binaries (CPU and GPU support) and they need a libOpenCL present - even if it is just a dummy/fake lib (for CPU only clients).

Project looks interesting.

The server I was planning to allocate to contribute has no GPU @ Ubuntu 16.04.

I made it trough ./LBC -h and got stuck at ./LBC -x

Code:
# ./LBC -x
Will use 12 CPUs.
You have 1996.6953125 MB memory and running 12 threads requires 6600 MB.
I've reduced the requirement to 3 CPUs.
Testing mode. Using page 0, turning off looping.
Benchmark info not found - benchmarking... ./kardashev-westmere: error while loading shared libraries: libOpenCL.so.1: cannot open shared object file: No such file or directory
Generator validity check failed. Expected: 5, Got: 0

no gpu = no opencl

*edit:
Googling lead me to your original thread.   Seems like OpenCL is required.   More reading to do.
