[XPM] [ANN] Primecoin High Performance | HP14 released!

[teknohog]

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.

I should probalby have linked to the readme instead. These are some of my personal cryptocoin scripts I've been building up since 2010, and I'm not sure if they are useful to anyone else, but feel free to grab some ideas.

I've just downloaded the new wallet. It won't sync and says: No block source available.

What should I do?

I don't think that's quite it, but it's close.  I don't think this is a case where we can use 30 as the ratio between each chain length; empirically it seems to be off, at the very least--I've estimated it as closer to 12 by looking at the gap between 1- and 5-chains.

Also, that would not be the blocks per hour; it would be the number of 8-chains per hour.  Primecoin has a fractional difficulty that is roughly linear, so if the difficulty is 8.5 then about half of all 8-chains are not valid work shares.  If the difficulty is 8.99 then only 1 in 100 8-chains are valid.  You need to account for that before you arrive at blocks per hour.  Generally it is blocks per hour = 8-chains/h * (1+difficulty-floor(difficulty)), but when you get close to the next integer difficulty things get weird since 9-chains work for difficulty 8.XX and 9-chains are more common than 8.995 chains.

Aha, so while the integer part is logarithmic, the fractional part is linear? I thought the fractional part was represented in a way that makes the entire number smoothly logarithmic (if you have something linear, just take the log, then the addition of these parts corresponds to multiplication in the "original" difficulty space).

Of course, if there are these complications close to the next integer, it won't work exactly, but it might be a useful estimate for long-term block rewards anyway. It's not like mining calculators can guarantee when you find the next block In fact, whether the fractional part is logarithmic or linear won't make such a huge difference, because a huge majority of the difficulty is in the integer part. (Putting my physicist hat on - we're interpolating between two points we know to be correct, so it's hard to make any huge deviations, especially when you are close to either point.)

I admit the base must be much more like 12 than 30, when looking at past block rates. I wonder where the 30 came from, though, I recall seeing it in a number of posts...

You probably need some nodes. Add these to your config file.

addnode=107.20.202.112
addnode=54.225.123.87
addnode=54.224.142.224
addnode=184.72.193.229
addnode=23.20.77.101
addnode=54.224.95.193
addnode=54.234.90.173
addnode=23.21.2.143
addnode=23.20.0.137

Can you post a general config setup for me here?

It looks like the seed nodes are getting pummeled a bit, one of the side effects of huge popularity! I think if you're patient a spot will open up.

well

looks like I have stopped finding blocks....diff to high now....

have not found in hours!!!!

what is best primecoin mining client?

meh


I;m looking something for win 32bit

[junglist.massive]

btw casio4life

[junglist.massive]

I know that I can mining on wallet but I'm looking for something faster for win 32

Again, it's around these forums. Look for mikaelh.

Huh, isn't that what this thread itself is about?

(I guess if I read the first post of the thread I'd know that, but I haven't in so long and these questions really have me wondering now...)

If the objective is an external mining program, then there might be bounties one can contribute to that aim at getting such a thing built, though maybe mostly they want it to be able to use GPUs.

There is the luke's miner prime branch project too though which maybe hasn't even had bounties thrown at it yet...

Does anyone have a clone of the repo?  Github has taken it down for excessive use of resources.

Edit: sf link, duh

Yeah the people who provided links to such repos right here in this thread do, or are theirs down too now?

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...

Thanks! I finally won't use it. primecoind runs fine for me. Turn my rig on 12h ago and already got two block

Same here. 3500 PPS
Nothing in 72 hours. Was getting 2/3 blocks per day before.

But then again, since I changed to HP4 from the Sunny's version i've had nothing.

I can assure you that mikealh's hp4 is the best version out there.  The reason you're not getting blocks is now high difficulty & bad luck.  I have several 10k PPS machines and some of them are not finding blocks in 24 hours now.  Then I have others that have found 3-4 in the same time.  Just be patient.  Or try the pool.
