Both of those clients at least open. but seem to crash as soon as it connects to the network. upnp issue maybe. Will see what I can find out

OK. First builds from today I accidentally had UPNP disabled by default, this time I changed it back to enabled by default which is how my builds from yesterday were set up.

Here's another to try: https://www.dropbox.com/s/lbua3xh5exypx75/release16_sandybridge_i5_conservate_opt_w_mfpmath_sse.zip

This has the -mfpmath=sse flag added. Shouldn't make a difference for you I wouldn't think, but it's the only other thing I had enabled yesterday that I don't today.

I just found this thread. New to Primecoin and trying to catch up on all of the news/info/updates/etc..

I just installed your release 11 build a few minutes ago and it's crashing immediately. Client doesn't even start to open up, just gives me the option to close program or check online for a solution.

Here is what I'm getting in the "Problem Details" box:

Problem signature:
  Problem Event Name:   APPCRASH
  Application Name:   primecoin-qt.exe
  Application Version:   0.8.3.0
  Application Timestamp:   51df5d09

  Fault Module Timestamp:   51df5d09
  Exception Code:   c000001d
  Exception Offset:   0044ddd1
  OS Version:   6.1.7600.2.0.0.768.3
  Locale ID:   1033
  Additional Information 1:   a061
  Additional Information 2:   a061d8dea3d3bcbdfe0bd2e856155b86
  Additional Information 3:   24f8
  Additional Information 4:   24f83b5f4f2ba50c807be2644334ea41

Hope that helps  Grin


That is because someone is building compulsively all combinations and subsets of compiler flags (avx, corei7, corei5, native etc) and optimizations (blockhashheader, size of siege etc),  and people are executing without thinking if it is optimized for amd, corei7, sandybrige etc  and the risk of forking because mismatching types and data interpreted differently  by architecture. Besides, home optimizations are been mesh without warranty they are sound with source released.

Hi anonppcoin

I have been using your build. Thanks for it . Just sent some XPMs to your way. Can you confirm your optimization is compliant to Sunny King's suggestion at https://bitcointalk.org/index.php?topic=253662.msg2709748#msg2709748 ?

Zalfrin's builds are working fine for me, I install the regular client and replace program files content with his stuff...works like a charm.

Here's the last build to try from me tonight... this one just uses -mtune=generic so it should run on most CPUs supposedly...

https://www.dropbox.com/s/ol7z6bt7hhml2v5/release17_generic.zip

The first build that runs on my machine after your first one. Thanks and sent XPM to you.

Thanks for all your help. Sent you a blocks worth.

The last one worked! No idea why the others wouldn't. SB i7 an all.


Awesome, at least it worked for someone. Smiley

The last build worked for me too now.  i5 Ivy Bridge

Thanks

Sending you a block once  it arrives as well.  Those were significant gains.

I notice some users releasing builds with changes to protocol related code without my review. This is dangerous. If you want to optimize that aggressively you should be working on an external miner instead.

Please remove any optimization code touching protocol related functions such as Target* functions, CheckProofOfWork(), ProbablePrimeChainTest() etc.
this wouldnt be an issue if there was an official build with the current set of optimisations

+1

Mr. Sunny King,

If you want to avoid the fall of this special coin, please do something. This is kind of sad that random supporters are doing the work instead of you. The heart of a coin/business is a good team behind it. Take a look at Phenixcoin. It is a scam shit coin. Copy paste. But the team does everything to promote it, so it ks gaining value.

Megacoin supporter bashing altcoins for being copy-paste.... Don't make me have to choke a bitch!

+1000


CHECK!  +1001

So far I have a i7 3770K that is mining great blocks are always in sync.  
But my 3970K Orphaned 6 blocks last night and two more today.

I have had 8 orphaned blocks and 1 legit block I keep looking at the block sync and its off sync every hour or so.

Not sure why they are different.  I have tried rebuilding with regular client.

I'm so sorry but all your releases crashed in my computer (Windows XP Intel Core2 6600 @2.4GHz)... I don't know why...

Here is one more build, it's probably extraneous with the two I've already provided, but if anyone wants to try it out they can. Again built from official codebase. This one is optimized for the core i7-avx.

https://www.dropbox.com/s/b3a5d3k6xt0ezvx/release13_corei7-avx.zip

You think this might be better than anonppcoin's version.. on my 3770k?

if you're only setting a couple hundred pps mining isn't worth it. Difficulty has shot up in the last day



Because Primecoin will never be worth more than it is today... ever...

You must know a lot about these markets then don't you.  hahaha

I'm making a couple of extra builds here, mainly to gain a bit of experience as I need it once in a while. I'm doing a Pentium-M, Atom, Athlon64(for the guy in the laptop) and a core 2 duo build, I'll upload them as I can. All are compiled with -O2 as if I use -O3 I get some errors with rpc stuff at the end, the file runs but it may have bad functionality.

Barcelona (AMD K10 parts), this one is -O3, threw some errors at the end but it works fine for me.

Either your missing boost or your INCLUDEPATHS in makefile.unix are wrong.

I don't recall having to install boost though on a vanilla image of 12.04 server (I will look into it later).

Here is a replacement for release5, again using the official codebase.

https://www.dropbox.com/s/76eij0zcjx091am/release11_sandybridge_i5.zip

I will pull down the old links now.
Any chance at a Linux compile?

If you're running linux you really ought to be able to compile it yourself. Wink https://github.com/primecoin/primecoin
Good point. Where can I find your revision/sources?

The code I was building with for my old releases is here: https://github.com/Zalfrin/primecoin

But, it's STRONGLY recommended to use the code on the official github until the kinks on my fork have been worked out.
so besides the sync problem at start... is https://github.com/Zalfrin/primecoin working or not?

Thanks for the Core 2 build, there are still people stuck with these things Smiley

Unfortunately I'm getting ~40% lower PPS than anonppcoin's build

Try this x86-x64 one https://bitcointalk.org/index.php?topic=253662.msg2710575#msg2710575
Both have about the same performance on my Core2Duo and should have the same codebase.
