The network is growing - It is good...

I've noticed the speed drops to the night and the morning starts to grow.

This is probably someone mining at work.

4xGPU running on GPU miner and CPU have 100% load  Shocked W8.1x64 8Gb RAM

Yes, the GPU miner needs lots of CPU power behind it.  Right now it's not very efficient to use your GPU's.  I have my mining rig CPU mining GAP and my GPU's mining other coins.  This way I get paid twice for my efforts  Wink

yeah, i back to this scheme too.

Best to mine this with a server board that can have 2 or 4 cpu sockets. Intel Xeon with 12 or 15 core with HT for 24 or 30 threads, would be power efficient ways long term but costly initially for the hardware. The gpu miner needs to offload work more on the gpu some how to make it more efficient. If you compare gpus to the recent i7 with 6 or 8 cores, they beat this immensely and even a 4 core i7 or AMD FX 8 core do better still too...

Hi,

I'm currently still working on the GPU-Miner, got some promising results (2x-3x speed increase),
but it's still pretty buggy, and needs more testing.

I'll do pool software next.

Hi there,

just wanted to give a little status update on the GPU-Miner.

My current idea is to divide the sieve into parts of the required gap size,
then apply dcct's strategy to each of those parts,
by start testing prime candidates from the end of the part and skipping those parts which have a prime in it.

One problem is, that you have to store the first found prime (if there is one) from the previous part in the current part,
to efficiently scan the whole sieve.
This and some other related problems lead into very difficult code.

Currently it's produce invalid results most of the time,
but I still think that it will give a reasonable speed increase to be worth the effort.

For testing I use either testnet or my account at nonce-pool (j0nn9) which is donating 100%  Wink

I'm sure that is the case - hence the quote marks.  It was more a mockery of the FUDers  Tongue

Even in test mode if you use the new Mayr increase the speed of the GPU 2x-3x sure that the complexity will Difficulty to 27-29, but that's where it leads?  Roll Eyes

Improved GPU-Miner (experimental):

Windows: https://github.com/gapcoin/GapMiner/releases/download/gpu-miner-rev3/windows.zip
md5: 6e0fa4a4331c3758bec1fc74334aa753

Linux: https://github.com/gapcoin/GapMiner/releases/download/gpu-miner-rev3/linux.zip
md5: 85bb6f69b22de5e51388155e7b532195

Source Code: https://github.com/gapcoin/GapMiner (branch gpu-miner)


The Miner is still a bit buggy, but it produced good results for the last few hours,
so I decided to release a test version.

About the speed: I managed to get around 1,200,000 pps with a single AMD R9 280, that's a 6x speed increase to the previous GPU-Miner.

I could also reduce the memory load.
Only the Sieve still runs on the CPU.

Also the 10 and 15 gaps per hour are replaced with tests per second,
which are the number of primality tests calculated per second.


The algorithm:

The sieve is splitted into parts of the required gap size,
then simultaneously, the prime candidates from each part are tested,
starting from the end of the part and skipping those parts which have a prime in it.

When using the -e switch you'll get an info about the current average number of prime candidates of those parts
(candidates which are not tested yet).
Also the minimum number of prime candidates to test are listed.

In one gpu run, several candidates from each part are tested,
you can control these number with -n


Debugging:

For debugging there are two options added to the Makefile,
one for debugging while mining, these are some tests, which shouldn't have a great impact on the pps
and one for debugging only. Activating the second option will run several time intensive tests while mining,
which has a huge impact on the pps.

I'm getting some good results, really nice work.

1,350,000 PPS on Radeon 7970.

Strange this is, I'm getting 1,750,000 on a lower end GPU (Radeon 7850).

I have 0/0 tests/s on the 7850 though. Is that a bad thing?

Beta launch of our new mining pool is currently scheduled for January 5, 2015.

We will feature Unitus merged mining for the yescrypt algorithm upon launch.

If you are a CPU miner and would like to help test our yescrypt merged mining implementation, please send me a PM for stratum connection details.

I get 2.1m pps on my r9 290x on default settings. These seem optimum, as most settings don't seem to change anything. With sieve-size lowering it by about 600kpps if I go up or down.

It runs fine using -t 1 so I figured I could run the cpu miner as well but that caused the GPU to half in speed. Is there any way to run them both or is it a choice of 1 or the other?
