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

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.

First number from wikipedia 19ch, second is found 15ch from block 2592901.

Good  Unfortunatelly, block reward same for chain with 11 and 15 numbers

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.

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.

lol to the btc dump xpm pump like usual

Thats nice.

Is video memory size important for gpu miner? Will it work on 4 or 2 Gb cards?

What cards do u have?

[Dekor]

What cards do u have?

RX550 2 Gb and RX570 4 Gb

[soulmann]

What cards do u have?

RX550 2 Gb and RX570 4 Gb

570 should by fine. Dont know about 550.

570 should be fine.

[Hann]

are there any fpga miners?

[buny]

By 2011, the largest known chain of Cunningham of any kind has a length of 17. The first was found a chain of the first kind, beginning with 2759832934171386593519, (found by Yaroslav Vroblevsky in 2008).

Hi eXtremal
Could you add a backup server and failover functions in the new version?
xpmforall has only one address.
Sometimes it disconnects all my miners. Sometimes i get a very high latency

it would be great if he can do that.

[kev7112001]

their are failover functions already also you can use script or use restarter programs should have stuff like this down just for any mining/miner as you cant always expect such support  

the basic in the config.txt
# GPU crash handling (properly untested feature):
# 0 - do nothing
# 1 - close miner application
# 2 - reboot system (need superuser rights)
onCrash = "0";

for those on win and want a easy GUI

whole bunch of new these days but back in the day i helped with this still works if you just rename exe on any miner

Failover functions will be full enabled in 10.3, now it not works correctly on all systems.
First priority for next release is CUDA version.

[hopguide]

Why 11ch =/= 10x 10ch?
12ch = 11ch I can understand, but why not reward the blocks finders?

hi my friend))how your sweet holidays?
when you want release miner vers 10.3 on windows?which dates or months?

[eXtremal]

Pool must reward miners according to hash rate only, not according to luck.

Why you decide about holidays, too long time without new miner releases? Yes, because 10.3 will have a lot of new features.
I planned release 10.3 at 15-20 May, but at the end of April I release CUDA port of 10.2.2 for testing.

Luck? I found several blocks, but was credited less than the half I should have got. I am going to solomine then. It was a good experience there though, just not good for bigger miners.
