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  

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.

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.


some 20 MHash/s already...  Beats my CPU!   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

Christian

looks like it everyone who went and bought cpu farms won't have the advantage anymore!

That was fast! I'm getting ~40 MHash with my 780. PCI-e 3.0 x8 here.

Wonder why the big difference, you on PCI-e 2.0?

yes, I am on PCI express 2.0 (MSI K9A2 Platinum V2 mainboard)


insert this at the end of do_keccak256 function

    checkCudaErrors(cudaStreamSynchronize(context_streams[0][thr_id]));

remove this from scanhash_keccak function

    cuda_scrypt_sync(thr_id, 0);

This will possibly double your hash rates.

Im running full pci 3 16x so I shouldnt be getting any bottle necks for my 780. How are you testing these?

Just download the latest, set the algo and run benchmark?

copy my command line I'd say...

Up to ~46 MH now so it's an improvement, maybe I'm hitting the limits of 3.0 x8?

GPU utilization at 60%, btw.

Ok so we don't need a cloud server...
I went and read the announcement. So its just like any other coin...except the retarget rate is much faster and its a different algorithm?

Are you testing in Linux? Not sure if it'd make a difference but I'm in Windows right now
