Im using the version found here: https://bitbucket.org/pankkake/mikaelh2-primecoin on ec2 ubuntu 12.04 cc2xl. I am getting 15kppps and thats awesome but it seems to be randomly stopping and needs to be started up again.
Anyone else experiencing this?
I have the same problem with 8core ubuntu. How can I fix that?

could anyone do the math about the ratio between 5-chains and 8-chains?

^ awesome. tyvm.
I ran settxfee 0.01 and it returned true. Should I be good to go now?
edit: doesn't seem to be the solution.
not sure what to do.

Write a shell script to run another instance when the previous one dies.

I found that the ratio between 1-chains and 5-chains was approximately 124, which would suggest that the ratio between N-chains and N+1-chains is about 12:1.  That would suggest that there are about 123 5-chains per 8-chain, or about 1,728:1.

If that ratio holds (there's no guarantee that the ratio of N-chains to N+1-chains is constant) then a miner with 1,728 5-chains/hour should find a block every 10 hours when the difficulty is 8.9, every 20 hours when difficulty is 8.95, or every 100 hours when difficulty is 8.99 (all of these are rough averages).  This math should not be taken as anything other than a crude approximation, but it should give an idea of order of magnitude.  My experience has shown that this approximation is at least within a factor of 10.

By using enough RAM, maybe? How much RAM you got and how much swap space?

Gentoo ebuild of hp4:

https://github.com/teknohog/ebuilds/tree/master/net-p2p/primecoind-hp

BTW, in case you wonder about different ebuilds from different people, mine are not just straight from the source, but based on bitcoind from Portage. They include a patch to use system leveldb, instead of building its own copy each time.

This shouldn't be taken as 100% correct, but I seem to remember it being mentioned that each step up in chain length is a 30 fold increase. so an 8 length chain would be 30x more difficult than a 7 length chain, and a 9 length chain would then be 900x more difficult than a 7 length chain.

Again this is from memory, if I can find the post again, I'll add a link (though the math a few posts before this one looks reasonable too!)

So in other words, your average rate of blocks per hour would be the 5-chain rate / 30^(diff - 5). Time to write a script...

Edit: updated the script.

Ghmm, seems i have much higher block rate for my systems

Why did you write this script? what did you change, and what problem did you solve?

Looks to me that its a python script, basicly a frontend for,
currency = {
    "bitcoin": "BTC",
    "chncoin": "CNC",
    "litecoin": "LTC",
    "namecoin": "NMC",
    "ppcoin": "PPC",
    "primecoin": "XPM",
}
Makes bitcoind/primecoind/... usage easier, etc. updated script also tries to estimate block finding time for XPM also.

Hi all!
Is there any guide to build primecoin-qt on ubuntu 13.04 or someone could help me? (I saw a screenshot on ubuntu)

Just cd into the source directory (usually 'primecoin') and compile the qt client:

Code:
qmake bitcoin-qt.pro USE_UPNP=-
make

that's all... the binary then appears in the source folder. Of course it might stop while missing some dependencies, but it will tell you... Wink
