I see that the keccak kernel is now in the latest build, but how do we mine VTC with it? What are the command line parameters?

no it isn't it's work in progress. And it's meant for low N-factor scrypt-jane coins...

Ahh a new coin type ay?

Here is a useful script for Linux user who find their nVidia driver gone AWOL... happened to me today after a reboot following some Ubuntu system updates...

Adjust the modprobe command for your specific driver version. run with root privileges.... you can even run this periodically in a cron job...

Code:

#!/bin/bash
timestamp=`date`
modprobe nvidia_331

if [ ! -c /dev/nvidiactl ]
then
    echo "Server $HOSTNAME device files re-created at $timestamp"
    
    # Count the number of NVIDIA controllers found.
    N3D=`lspci | grep -i NVIDIA | grep "3D controller" | wc -l`
    NVGA=`lspci | grep -i NVIDIA | grep "VGA compatible controller" | wc -l`

    N=`expr $N3D + $NVGA - 1`
    for i in `seq 0 $N`; do
        mknod -m 666 /dev/nvidia$i c 195 $i;
    done
    mknod -m 666 /dev/nvidiactl c 195 255
else
    echo "Files exists"
    exit 1
fi

cudaminer output before and after...

Code:

mine vertcoin with --algo=scrypt:2048  and use a vertcoin pool.

there's no keccak involved here.

currently you cannot mine low N-factor coins with cudaminer. Keccak is CPU bound at the moment
So the N-factor has to be 11, 12, 13, 14 for mining to be feasible.

I am working on a GPU based Keccak implementation right now.

ok
fine

Is cudaminer done, meaning its as fast as it can get?  On my 780ti I do around 650kh/s.

But isn't that still around 200 behind AMD cards?

Don't think nvidia will have high end maxwell till the end of the year.  So going to be a long wait for another boost.

[bathrobehero]

@cbuchner1: Do you solomine with the default 8 active connections in the wallet, or have you increased it?

[_Wolverine_]

Anyone mining Vertcoin? If so where (pool or solo)? And how many hash/s?

[liomojo1]

I am mining vertcoin in this pool http://115.28.31.155/using gtx760 and get 145-150 max khs/s

AMD at stock clocks aren't much faster either. Practise some overclocking zen.

how to increase? ;-)

Open the port on your firewall, enjoy 36-60 connections...

[bigjme]

Any benefits to it?

Lol chinese pool 

thanks for the info, think I will go to vertcoin

I already use rpcallowip and the port is open to my internal network.

PSA: Avoid at all cost to have that port open to the Internet. You can initiate funds transfers etc if you know the RPC password.

I was mining there alone (nobody could see it  for 2 day) and i got 2 blocks , now more people came to it and i have little shares now but , for 5 days minig for 10 hours sometimes less a day i have gained 120 coins. I dont know if it is ok , but this is my first attemp to mine. And it is all , because of the marvelous work of the guys here. Thank you very much.

In most wallets you can increase it with command line options or with the wallet .conf file.

Code:

-maxconnections=<n>    "Maintain at most <n> connections to peers (default: 125)"
-maxoutbound=<n>       "Maintain at most <n> outbound connections to peers (default: 8)"

With more connections you can reach the whole network with less hops. And it might help finding less orphans. Not sure.
Also, with more connections you can download the blockchain faster (if you're not CPU and/or IO bottlenecked, which is generally the case).

The reason I asked because I solomined YAC for days and found nothing, not even an orphan block and I just recently increased the active connection limit and was not sure that it would have any connection between solomining. I guess it doesn't.

As far as I saw Vertcoin is hardcoded for 8 connections, it reaches it in a couple of minutes and then (looking at the debug.log) it stops any network discovery until a connection is lost. Not sure if that is a good idea especially that the default timeout is 5000 ms for connections, so the wallet could theoritically pickup pretty shitty, high latency connections and keep them. You can decrease the default timeout delay, though.
