Thanks Mikael, I read that it takes a 30 fold increase in processing power to increase difficulty by 1 . . . if so difficult to imagine difficultly ever climbing beyond 12 or 13.

999/(13*13) =  5.9 per block


i thing there are about 1000x optimization left in the code....at least

so . . . 999/(15*15) =  4.44 per block


I think diff at 12 is the time GPUminer approach Smiley

Experimenting with sievepercentage and found 100% caused a segfault.

Good question.. can anyone attest to this?

How much time it takes to found a block?
I just using this primecoin-hp on my i7 with the mining speed about 4000-5000 pps for couple of days and still nothing...
Is it how it should be?

I've been consistently finding blocks once per day with my Core 2 Quad 9400 OC'ed to 3.5GHz on the second windows client.  My pps is usually around 2500, so I'm either very lucky or something is wrong on your end.

I can attest to you being lucky.  I've been running a constant ~2700 PPS for almost 48 hours and haven't found squat.

/primecoin-hp/src# primecoind stop
error: incorrect rpcuser or rpcpassword (authorization failed)


Your primecoin daemon was started with a different password in the config file. Just kill it off by typing:
Code:
killall primecoind

Same thing over, and over again. I have killed it, and hes coming back.

Find the script that is restarting it and kill it using "kill pid".

If you followed Mikaelh's build instructions then you have a script running that restarts primecoind when you kill it. You need to kill the run-primecoin script first then primecoind.

My pps went down after I changed the sievesize from 1M to 2M.  Should I be worried, or is this "normal"?

it's normal !

Question. Any way to change sieve % in Debug console (Windows QT)?

It's looking like mining is getting significantly less profitable without a gpu miner.

says the guy with 400-500k pps. lulz

It's not free to run that many pps. This morning it was looking like I might not beat my costs by that much. I know how it looks though Wink

I've been consistently finding blocks once per day with my Core 2 Quad 9400 OC'ed to 3.5GHz on the second windows client.  My pps is usually around 2500, so I'm either very lucky or something is wrong on your end.

Or, we could just have things set up incorrectly.

Not likely...  i have found many blocks, but less then one a day for the last 4 days.  it is just getting that much more difficult!

edit:  ( I turn the rigs down to about 7-8k during the heat of the day )

-hp6 released!

[...]
 This release attempts to fix the random crash while mining. I'm not sure if it's actually fixed because I have heard both positive and negative reports. The crash is more likely with high number of cores. 16 and 32 core machines are suffering the most.
[...]

As far as as I can say it runs better, but I've had one crash on Windows 7 64-Bit (Phenom 2 X4 955 -> 4 cores):
Code:
Title: MinGW Runtime Assertion
Assertion failed!
Program:
C:\Progam Files\primecoin-0.1.1-hp6-win64\primecoin-qt.exe
File: src/checkqueue.h, Line 141

Expression: pqueue -> nTotal == pqueue -> nIdle
I can add a screenshot, but I thought text that can be searched for by other users might be needful Wink
