[gudmunsn]

since I started mining with release5.zip about 6 hours ago I have found 4 blocks with 2 i7's at average speeds of 940 and 840 pps.

Congrats, my good man!!

The PPS has certainly jumped some 5-6 times for me. Hopefully will get a block soon.

Any feedback about anonppcoin's release? Testing it on one machine and getting very high pss but no blocks found yet.

Same here, but I just switched released. Will let you know if I hit a block with it.

well, i found 2 blocks with the release of Zalfrin and two with anonppcoin in less than 6 hrs, maybe lucky

Same here... high pps but no blocks... I think is like Pirelli advertising... "Power is nothing without control"   (at least at the moment... )

What's your total PPS? Yeah I know, they are estimated numbers

i2500k stock average of 550pps

With anonppcoin's release my primespersec have shot up. Yet to find a block though. Seems a lot more resources have now been put on this.

[tadakaluri]

I have been alerted that certain classes of system continue to experience extremely low primespersec values. Upon investigation it seems certain systems have performance problems with the sieve, causing extended sieve round time. A temporary fix is now pushed to github. Please note I don't have enough time yet to fully test this solution, so try it out first to see if this resolves your system's problems.

Please report back if this resolves your performance issues.

Have you updated Original Download files with these changes?

Hi,

trying to run FuzzyBears primecoind I get (on Ubuntu 12.04) this error:

Code:

./primecoind: error while loading shared libraries: libdb_cxx-5.1.so: cannot open shared object file: No such file or directory

But libdb5.1 is installed:

Code:

apt-get install libdb5.1
Reading package lists... Done
Building dependency tree
Reading state information... Done
libdb5.1 is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 89 not upgraded.

..and as I still lack to compile by myself (but this is something completely different and can be found here: https://bitcointalk.org/index.php?topic=251850.msg2705099#msg2705099) I need a compiled version that works.
Looks like I have some issues with (my machine | my skills)

Am I alone with this issue?

FYI, here is the code base I have been building from:

https://github.com/Zalfrin/primecoin

Thank you, I'm observing 3 fold increase in PPS (compiled your git on Linux).

Just pushed another commit on github.

sieve round limit further reduced to 1 second.
added mike's suggestion.

Give it a try and let me know how it goes.

This nearly tripled my PPS from the original release.

Now getting 2000-2400 PPS on an i7-980X @ 4 GHz. 7 blocks found so far (of which 1 was orphaned).

Compiled with -O3 -march=native.

Hej,

I had somewhat similar issue when compiling on OPENSuse, but not with the same socket. Maybe you should check whether libd_cxx-5.1.so is included in your /usr/lib (or the like) directory and linked properly.

Thanks for the update, I was concerned it wasn't working right as I still have yet to mine a block with release5, but my luck must just suck.

Should the "-O3 -march=native" be in CFLAGS? Should I change

Code:

make -f makefile.unix

to

Code:

make -f makefile.unix -CFLAGS="-O3 -march=native"

?

Thanks,

Ha, and now my release5 has finally found it's first block for me as well. Yay!

Something like that. More specifically:
