Thank you the update! 

Do you mind sharing your settings as I am only getting 700k pps with my R9 280x ?

@j0nn9
where I can get a copy of the logo in high resolution?
Thanks!

Best I've been able to get with a radeon 7970 is between 1,500,000 - 1,700,000 PPS with the following settings:
-g -j 5 -n 4 -w 1000 -i 50000

The flags used above are explained below:

Enable GPU mining:
-g

Stats interval (in the settings above, I have stats printing every 5 seconds):
-j

Number of tests per gap per gpu run:
-n

Number of primes for sieving:
-i

Tried many different values for the -n and -i flags and actually had it around 2,000,000 PPS, but the test/s kept going to 0. I preferred stability so I adjusted the settings to lower the PPS and keep tests/s high.

A few other settings that may have an effect on PPS, just for some quick reference. These can all be seen by running the help command ./gapminer -h:
--work-items (gpu work items - default: 2048)
--queue-size (gpu waiting queue size - note: memory intensive)
--sieve-size (prime sieve size)
--shift (the adder shift)

I want another poll and another exchange, poloniex killing this coin.

I want a better CPU miner send me pm and we can make a good deal.

Ok, if yours does not do it, it must be something to do with my PC, I have a few more R9 290x's mining other things that I can try this weekend. Just FYI though, the CPU I am running is an i7 4790K so I don't think it is CPU load here that is affecting it.

It seams that on your system it's just one or the other,
but I wouldn't generalise it. It probably depends on the actual cpu.

Sorry, I meant on the cpu miner I ran -t 1 as well, to test it. It still caused the slow down. So to confirm

So both the gpu miner and cpu miner running -t 1 causes the slowdown.

You could try to reduce the thread count on the cpu miner.

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?

Now 0.02 GAP at a time and new simple capcha.

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?

It's so obvious what that is.

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.

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?

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

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