Topic: Open Source XPM (Primecoin) GPU Miner & Pool xpmforall.org - page 27. (Read 109915 times)

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.

Primecoin searches a much more big primes, now minimal length is 320 bit.. it not so easy.
First number from wikipedia 19ch, second is found 15ch from block 2592901.

Why does wiki say that there is 19 Cunningham chain? We mine primecoin for several years and only find the 15 chain?

oh, it's me   

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

Also, you can look details here: https://primes.zone (Cannot give direct link, website not support it.. go World Records, then click TWN).

that ratio is same for 11ch, 12ch, 13ch ...?

1 10ch = 10 9ch = 100 8ch = 1000 7ch.

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

@eXtremal
what is share values for 7ch, 8ch, 9ch ...?

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 ?

Whoa. Did someone just mine out a 15-chain?

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";

how much appreciated?

fanspeed =       ["-1", "-1", "-1", "-1", "-1"];


If I put "sieveSize = "210";", the program closes automatically.

Why my GTX have all these "invalid shares" ??

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
