[XPM] Primecoin Built-in Miner Sieve Performance Issue

[itod]

This is my build, I used -O2 -march=native, I'm running a FX 8350, it gives me ~1250 PPS on that. I placed all the dlls in the rar. Please do your virus check and everything, I compiled that on a VM but still take precautions running a file made by another person.

Wov, this thing flies. On my i3 four cores @3Ghz now have 350-400 primespersec! Original 0.1.0 client has around 50, version 5 from last nigh around 150, and now at least 350 with your version. If it is really that fast and not some error, I would mine a few blocks tonight. Will let you know.

Thanks, Zalfrin!

What CPU do you exactly have?. To try to make a better build, after all it's experience to me.

Intel i3 540, 4 cores, 3GHz, 8GB RAM.

pps now varies 400-440. I highly recommend this Zalfrin's build, but still think that this high pps may be a mistake. Will see how many blocks I'll hit in next 24 hrs.

[Jimmy2011]

Thanks.

Should I add the port number? For example,  "addnode 65.29.242.236:51193 add" or "addnode 65.29.242.236 add" ?

I started to mine though it's not synchronized, and I got 450 pps. I am so luck that I got a block in 2 minutes. So is it an orphan block?

If your blockchain isn't synchronized, then yeah probably an orphan.

I haven't used addnode before, but your second example should be right, from the console window.

I have 8 active connections, but only 2 blocks synchronized.

It's a little strange.

Yeah I found my first 2 blocks with Zalfrin's 5th build on my i3 3225. Thinking maybe that is the right build for my processor instead ofthe x86-64 build.

PPS sounds about right, I get around 600 PPS with my 4.4GHz i5.

Now actually getting a block, is pure luck... Lots of miners running with these optimizations now. I've only gotten 1 block on my PC since these code updates came out. I've gotten 4 on my cloud servers.

just need some quick assistance.

make: *** [obj/alert.o] Error 4

when i try to compile the primecoind i keep getting this error.
note: i have other wallets compiled with this ubuntu 12.04 server so i know i have all the requirements for those.
Thanks

Woot! Yours is the first updated version that works for me. Thanks!
Getting 406 PPS on an AMD Phenom X4 965.
EDIT: Make that a 581 PPS

Thank you!

You're out of memory, read this thread for the fix: https://bitcointalk.org/index.php?topic=252944.0

Also, note that your command is wrong. Should be USE_UPNP=- , not USE_UNPN.

[x3maniac]

OMG you are right! thanks. i forgot to make a swap part

[tocket]

I get compilation error.

This is the make file command:

make CXXFLAGS="-O3 -march=native" -j6 -f makefile.unix

and this is the error.

g++: internal compiler error: Killed (program cc1plus)

What's the solution?

Not enough memory. Make a swapfile or remove the '-O2' from the makefile

Memory is probably the issue indeed. I think it's the -j6 part that should be removed though (-j6 means it will compile 6 files at a time if I understand it correctly). Each compiler thread uses about 300 MB, so 6 will use around 2 GB.

[Zalfrin]

Here's an interesting comparison of compilers/settings, looks like I should try out intel's compiler.

[LazyOtto]

looks like I should try out intel's compiler.

Last I looked, several years ago, it wasn't free.
In fact, rather pricey unless you had a justification for the cost.

Has that changed?

You are correct, $1600 for the full C++ studio or $600-700 for just the compiler. But there is a 30-day trial available I might try out.

Here's another binary I've made which targets simply x86-64 processors. This SHOULD work over a wider range of processors than my earlier releases. It may not work on 32-bit OSes (not sure).

I don't know what that's about, I suppose you could try the last officially released binary by Sunny. Maybe that will get your blockchain downloaded, then you can switch back to the optimized miner.

Once you switch back, make sure to check with getmininginfo that the current block number increments at least every 15 seconds or so. I had 1 build that had some kind of problem with UPNP and never incremented the current block. However, I'm running this x86-64 build now and it is keeping up with the blockchain, so hopefully that will be the case for you as well.

Try using -debug and -printtarget and post the ERROR messages about block #3 being rejected again

Yes, stuck at 2 blocks, and now I am running the original clients and completed 95% synchronization. Let's see what will happen when I change it to release 5#.

Which miner and what commands i should use to test mining on Amd Phenom IIX4 955 processor? Is there any way? couldnt find one working
