xpmclient 10.3 development started, main target of this release - introduce CUDA version of miner with good advantage for NVidia cards and remove high CPU load on Windows.
Thats nice.
lol to the btc dump xpm pump like usual
Why does wiki say that there is 19 Cunningham chain? We mine primecoin for several years and only find the 15 chain?
https://en.m.wikipedia.org/wiki/Cunningham_chain
Primecoin searches a much more big primes, now minimal length is 320 bit.. it not so easy.https://en.m.wikipedia.org/wiki/Cunningham_chain

First number from wikipedia 19ch, second is found 15ch from block 2592901.In addition to being much bigger, the primes mined by primecoin have special limitation (the base prime origin must be divisible by block header hash) instead of any random number. I believe this makes the mining more complex and harder to find longer chains.

Yes, pool found new record, bi-twin chain of 15 numbers!
Block height 2592901.

oh, it's me
Unfortunatelly, block reward same for chain with 11 and 15 numbers

that ratio is same for 11ch, 12ch, 13ch ...?
Yes, same as 10ch. @eXtremal
what is share values for 7ch, 8ch, 9ch ...?
1 10ch = 10 9ch = 100 8ch = 1000 7ch.what is share values for 7ch, 8ch, 9ch ...?

you can do better, much better.
your compiled kernel is too big, it should be around 1193KB for better results.
how did you do it? your compiled kernel is too big, it should be around 1193KB for better results.

1 10ch = 10 9ch = 100 8ch = 1000 7ch.what is share values for 7ch, 8ch, 9ch ...?
Pools use PPLNS system, share cost depends on block value and total shares for last 1.5 hours.

With target=11 9.4.1 can work, but produce 4-5% invalid shares.

hi. 9.4.1 does not work because the pool code is changed?
No, because difficulty changed hi. 9.4.1 does not work because the pool code is changed?

Anybody tested hashrate of R9 290x/390x on XPM with 10.2.2 tweaked miner ? May be ~0.54 CPD ?
I got 0.55cpd with Sapphire R9 290X Tri-X, xpmclient9.4.1

Whoa. Did someone just mine out a 15-chain?
yes, someone found that beast.

Hi, I have a problem with the GTX1060.
I have 2 R9 390 and 3 GTX 1060. The 2 R9 have all "Sher accepted", the gtx 1060 have continually "Invalid Share".
the Nvidia configuration file is this:
# Pool websites:
# http://xpmforall.org
# http://coinsforall.io
server = "xpmforall.org";
port = "6666";
# Your XPM payout address
address = "My addrss";
# You can give this machine a custom name
# Computer name is used as default
#name = "Nvidia";
# Platform:
# "amd": AMD GCN cards
# "amd legacy": AMD HD5xxx & HD6xxx cards
# "nvidia": NVidia Maxwell cards
platform = "nvidia";
# GPU crash handling (properly untested feature):
# 0 - do nothing
# 1 - close miner application
# 2 - reboot system (need superuser rights)
onCrash = "0";
# - Valid cpuload range: 0 to 4
# - More than 2 does not make sense
# - You can use 0 for really slow CPUs
cpuload = "0";
# Target Cunningham chain length, default = 10
target = "10";

You cannot mine with target="10", difficulty > 11 now.
Some people here talk about special kernels. I have good CPD on my Radeon cards, but how did some people get over 0.5 CPD per RX 580? I get 0.42 max.
Any suggestion are very much appreciated

how much appreciated?
I am not a large scale operation (10 GPUs only), so while it still matters to me its more of a thing that I wan't to optimize everything I can to the fullest. But if you mean if I am willing to pay? Well I can donate some ofc but not much. I am quite dry at the moment. If you want to share for the community then I am sure a lot of people will be very gratefull. But I will understand if you don't want to, so no problem.
