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

[vinne81]

39 blocks found in the last 12 minutes so people are still finding !

The question is how...

Blastbob mentioned something like 2.6M PPS

I'm wondering guys, let's say you operate a LARGE number of VPS, that use each other as nodes. All interconnected. Wouldn't that be in their advantage? The nodes would be superclose to a big source of new blocks (itself), and have a head start generating new blocks?

just upgraded to hp4 from hp1 and my pps dropped from 1700-2000 down to 700-800pps anyone else see this? i5 2.8 sandy bridge

hp1 limited sieve size too much, pps was up but block finds where down

I'm mining 4 systems each system over 10,000 primes per sec and Haven't found a block sine midnight. HP2

Anyone having these issues?

Pretty much the same issue. The difficulty is now very high and due its exponential nature it means that blocks are very hard to find.

As Primecoin nature is different than other coins I wonder if it's even possible that diff goes down and make it profitable again. Any thoughts ?

I am willing to bet difficulty will be heading down soon, its no longer profitable for VPMs

Yes, diff should go down if VPMs is not profitable anymore but, my question were "is that possible?" Can the primecoin diff go down ?

I think so, sure, why not. The dev (sunnyking) told days ago about the diff still catching up, and that is was "expected" behaviour. Diff is indeed still rising. Yes, there is a point where diff would drop, but it's not now. (correct me guys if this is wrong)

yes it can, i found block 16 at diff 6.99609262 below the 7 start

just upgraded to hp4 from hp1 and my pps dropped from 1700-2000 down to 700-800pps anyone else see this? i5 2.8 sandy bridge

hp1 limited sieve size too much, pps was up but block finds where down

So I should just leave it alone? So basically 700-800pps with hp4 will be better than 1700pps with hp1?

or try hp2

I'm getting loads of weird compile errors when compiling makefile.unix on centos6:

"alert.cpp:223: error: âitemâ was not declared in this scope
alert.cpp:223: error: âBOOST_FOREACHâ was not declared in this scope
alert.cpp:224: error: expected â;â before â{â token
alert.cpp:268: error: expected â}â at end of input
alert.cpp:268: error: expected â}â at end of input"

Looks like there are weird characters in the source?

You probably need a newer version of boost.

Hey mikaelh

I'd like to donate for your efforts, but I only have YAC available - you don't have to answer this, but what is a reasonable donation amount? (PM me if you wish).

Thanks for your hard work - I hope to gather some Primes, and then I'll donate again

K.

What's the best OS for this in this list?

ubuntu 12.04.1 server amd64
gentoo amd64 minimal 20121210
ubuntu 12.10 server amd64
gentoo x86 minimal 20121213
CentOS 5.8 x86-64
CentOS 6.3 X86-64
FreeBSD 9.1 release amd64
debian 6.0.6 amd64
debian 6.0.6 i386

It's a VPS, and only has linux options...

Are there any other CPU coins?

There are coins that can currently be mined nicely with a CPU, however that is because botnets and GPU miners are ignoring them. Basically they are working simply by (un)common courtesy, basically throw a core at each, compare your take with number of nodes, if it looks like everyone else must be using two cores or have core on average twice as powerful as yours throw another core at it.

This is what worked last year for a year or so with BBQcoin to allow small miners a whole year to accumulate coins slowly politely but surely at minimal cost in electricity that led to them all getting very nice payoff when enough people had enough coins saved up to make bringing it back into the limelight worthwhile. (GPUs then jumped on, difficulty went beyond what CPUs could reasonably mine but high enough for exchanges to risk listing the coin, the CPU miners got paid off handsomely or still have nice stashes of BBQcoins they are still holding or daytrading or whatever.)

Yet I'm having trouble compiling the miner: http://www.ppcointalk.org/index.php?topic=341.msg2361#msg2361
Haven't got an answer yet...seems to be a bug or something when doing apt-get install for certain dev files.

Yes, but there's only a small window to sell BQC or whatever coin before it becomes clear it has no future. No bad feelings towards BQC (I like the coin), but it has dropped very low and I don't see any way for it to get out of that position. Even if you have 100K coins, it's still worth almost nothing. Low diff or not, 100K took serious time to mine...

At least ten million got sold off by CPU miners, that did make quite a dent in the price but it still hasn't really crashed it maybe has merely found its price now that many or most large holders are people who bought them not people who mined them. Heck most BBQcoins whether large or small holder are bought BBQcoins now.

Allowing small miners years to accumulate coins seems to maybe be a more stable setup than these recent pump and dump coins, maybe? Maybe people who spent long long time slowly accumulating their stash are less likely to dump it all at cheapest price the moment an exchange opens?

sorry I upgraded from hp2 to hp4...Had 1700pps with hp2. So is hp4 with 700-800pps better or hp2 with 1700pps?

Uh ... how are you getting 10k PPS per system? Are they 4x CPUs or something?

[achillez]

just upgraded to hp4 from hp1 and my pps dropped from 1700-2000 down to 700-800pps anyone else see this? i5 2.8 sandy bridge

hp1 limited sieve size too much, pps was up but block finds where down

So I should just leave it alone? So basically 700-800pps with hp4 will be better than 1700pps with hp1?

or try hp2

how do you get back to hp2?
