Yes, after I do the following:
cd ~/primecoin/src
make -f makefile.unix USE_UPNP=-

It gives me this error

In file included from db.cpp:6:0:
db.h:14:20: fatal error: db_cxx.h: No such file or directory
compilation terminated.
make: *** [obj/db.o] Error 1

Your make didn't work for some reason, that's what builds the primecoind.

I see. That's why.. primecoind not in there. Where did I go wrong? back up and install it again?

Well, I managed to get the optimized client compiled. It's running about 100-200pps on four instances. I'm pretty proud of myself...linux is kind of frustrating when you're just learnin'. Thanks for everyone throwing it down in this thread. Super helpful!

See this post on the previous page, and the following posts where he fixes the problem. Can't remember if he said explicitly what his issue was for that particular hangup.

sudo mv primecoind /usr/local/bin/.

^^ Not working

/primecoin/src# sudo mv primecoind /usr/local/bin/.
mv: cannot stat `primecoind': No such file or directory


I am on ubuntu-12.04-x86_64

Hmmm...

Try moving all of your coins to your local wallet and then delete your droplet and start all over again.

I did that !!!!!

I press right mouse click and see nothing, ctrl+v doesnt work too.

I used putty and it works.

Compile and run the update in the original op:


Also apparently New York servers have the best performance.

I have the same problem as you really low PPS

I tried the 16 core and get 0-5 pps

the 1 core 20 pps

what am I doing wrong???

right-mouse click, paste

I've upgraded to the 16 core for the night and my pps is : 2391

Does the copy paste work? I can not paste code in ubuntu console.

good point . thanks!

wallet location is: ~/.primecoin/wallet.dat

In the same hidden directory you will find (or you can create it) primecoin.conf if you need it.

If you don't want all your droplets to mine with the same address you don't need to recompile anything, on the contrary after the recompile they would still mine with the old addresses from the previously created and unchanged wallet.dat. If you want not to mix found blocks from droplets, it is enough to delete wallet.dat on each droplet, restart the primecoind on each droplet, wallet.dat will be automatically recreated with new addresses, and they will now have found blocks of its own.

I've been using the cloned wallet and it's been working fine. Can't say if having separate wallets would give you better performance, but I doubt it.

So I made a snapshot of my orig droplet and spun up a couple new ones from that snapshot and noticed something interesting.
One of them mined a block ( yay! ) but it is showing up in each of the clone droplets. my guess is it's happening because they're all using a cloned wallet aka priv key .
I imagine that is not a big deal ... but my worry is that they may be doing redundant work, and trying to solve for identical things since theyre clones and not unique instances.
Crossing my fingers that since they all read off the blockchain, that they'd be trying to solve for different blocks from each other.
Either way, I'll probably just end up destroying them and compiling primecoin on each one, just to be safe.

Thanks, I'll remove it from OP.
