Use multiples of 200k for sieve size with HP5. One of the internal loops goes over 200k elements. If there's a small bug there somewhere, it might crash when sieve size is not a multiple of 200k.
Thanks for that info! Sorry for such a newb question. What is command to change sieve size? I didn't see config file for it. in primecoin.conf add "sievesize=...." Maybe im nuts... but can u tell me where to find primecoin.conf. Sorry again for taking up space in forum.

something weird is happening with hp5, I set sievesize to 4.8M started mining and went for a nap. Two hours later I find out the the client crashed. I try to restart it and it crashes again. I rebooted the computer, same. I cannot put any sievesize higher than 3.6M or the client crashes as soon as it starts mining. Was running fine a few hours ago at 4.6M and even found a block with this setting.

It's in Appdata/Roaming/Primecoin

Hit win key, type %appdata%, hit enter. Look for primecoin folder. Create it if it's not there already. New text document, rename it to primecoin.conf (you need to see file extensions to do so).

-hp6 released!
Lots of changes in this release. Here's a list of notable changes: * Added fast divisibility tests before doing the expensive Fermat's test * Lots of other small optimizations * Introduced a new experimental tuning parameter "sievepercentage". Default value is 10, minimum is 1, maximum is 100. * Added new RPC command "getchainspermin" * Added the following information to "getmininginfo": chainspermin, difficulty, sievepercentage, and sievesize * Attempt to fix the random crash while mining
My PPS on mainnet went up 23% with this release with difficulty >= 9 on mainnet. 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.
The "sievepercentage" parameter is there for people to experiment with. It limits how many base primes are used to filter out candidate multipliers in the sieve. 8% seems optimal for testnet but I have no idea about mainnet.

Thanks for the update, will be testing it on my farm.

Great work mikaelh !
I'll see if this fixes my strange crash with sievesize higher than 3.6M.

Sorry Tamis, still getting that same crash with the new update. I get the same crash with hp4, hp5 and hp6. All are the winx64 versions and it seemed to coincide with difficulty hitting 9. GL

GL I was wondering if this was related to difficulty hitting 9+ ! pps is down too so I'm guessing this is also related to the difficulty ?! Thanks palmface mikaelh can you give us some info about the sievepercentage parameter ?

True, can confirm crash only happens on my 16 core machines. The 8 core, 4 core, 2 core and 1 core never crashed. let's test hp6 on my farm ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

Thanks Mikaelh! Love having the additional stuff in getmininginfo. Can confirm my pps went up on an 8 core though still below were it was at before difficulty hit 9.
edit - pps improves more for me with sievesize=2000000 and sievepercentage=8

Anyone running many machines experienced a major slowdown in the block rate since about 14 hours ago? I was getting around 40 blocks a day, not it looks like I'm getting 20.

difficulty 9 already, that's the reason 40blocks? How much PPS you got?

What's the reason it is only 9? I'm trying to get my head around the idea that Quarkcoin launched a few hours ago and is already 57 difficultly.* Is that an apples to oranges comparison? Surely Quarkcoin can't have 6 times the network strength of Primecoin. As Primecoin difficulty rises, the supply of coins really gets choked off - at difficultly of 32 . . . that's 999/(32*32)= .975 coins per block. *Oh, it's gone up to 63 since I wrote those two sentences.
