I have access to maxcoin cpuminer code. Excellent. Launch was delayed 24 hours. excellent.

it's linked here: https://bitcointalk.org/index.php?topic=450539.0



Great. I was going to post this: http://pastebin.com/GD09hEcD but I don't know if it is to any help.

cudaminer is really awesome  Smiley , all other miners just doesn't do it with nvidia.

Sweet, looking forward to this new development Cheesy  Might be a fun programming challenge with not being able to test it.

Btw,

I think there's a bug with multi-thread with > 8 GPUs.

Even if you try to use -d9 now, it gives an error that cuda devices don't exist.. but worked fine with earlier submit.  (haven't isolated the regression CL yet though).

yes, my arrays are all size 8.  If you have more than 8 CUDA devices in one machine, this is outrageous Wink

the coin's announcement brought down bitcointalk.org. cudaminer might be the only viable GPU miner - who knows.

Sounds like a fun launch. I will be sure to set up the wallet now.

What configs should we use for cudaminer for this?

nope, wallet launches tomorrow 19:30 GMT. Only the miner code is available (big mistake on their side IMHO),.

Yeh. I had a download off their website for the wallet but it was empty.

Is there some sort of scrypt-jane: for maxcoin?
Want to get my mining config ready

It's SHA-3, only mineable on CPU unless cbuchner updates cudaminer to support it.

Code:
static void share_result(int result, const char *reason)
{
...
applog(LOG_INFO, "accepted: %lu/%lu (%.2f%%), %s khash/s %s",
  accepted_count,
  accepted_count + rejected_count,
  100. * accepted_count / (accepted_count + rejected_count),
  s,
  result ? "(yay!!!)" : "(booooo)");
...
}

How would I go about launching a bat file every time this occurs?

Finally!
System() is not recommended for various reasons, but it gets the job done. Using with mailsend I finally achieved what I wanted, which is an email for every yaay! message cudaMiner gets which is obviously only good for solomining, or for pool mining if you want to spam your inbox with every single share you've submitted  Wink

It looks like this, after the yay/boo line:

system("mailsend.exe -q -smtp smtp.gmail.com -port 587 -t xxxx@gmail.com -f xxxx@gmail.com -sub NEW_BLOCK -M PC#2 -user user -password pass -starttls -auth-CRAM-MD5");

In this case NEW_BLOCK is the title and PC#2 is the body of the message.

You can use something like a mailsend.bat if you want different computers to send you different mails with the same cudaMiner build, but then the mailsend launch line will show up in cudaMiner. This, however doesn't leave trace on the console, but you might want to make different cudaMiner builds with the different mail messages.

See mine at the moment checks the wallets for transactions, sends the new balance to a webpage which stores the values in a database for later look up, and emails me the new balance value and value in money. And the same for the old balance so I can see what I have made. Its not very quick however due to rubbish host email services

Currently you can test keccak in github. use the K kernel (just imagine K stands for Keccak).

The specified blocks/warps config is used for keccak. A good guess would be a larger multiple of your
GPU's SMX with 32 warps.  Fermi CPUs can only run 16 warps.

Autotune is definitely NOT working.

the keccak256 code for maxcoin is currently compiled against compute_10 which means it runs on any GPU.
Performance isn't stellar yet.

Code:
cudaminer --algo=keccak -d gtx780 -L 16 -l K192x32 --benchmark

some 20 MHash/s already...  Beats my CPU! Wink   Only 40% TDP. There's headroom!

More work to be done tomorrow. I need to get rid of the huge scrypt scratchpad buffers. They are not needed for keccak.
Also we may want to have some autotune. I currently use the -L parameter to artificially make the scratchpad smaller,
so I can run more blocks.

Uh, PCI express bandwidth is going to be a bottleneck at these MHash rates. Gotta do the hash verification on the GPU!
Without the device to host memory transfers I can hit 80 MHash/s, getting 75% TDP. So this is the way to go!

One AMD CPU core: 1 MHash. lol Wink
