Okay, the first GPU-enabled version is ready. Right now it only does the sieving on the GPU. Primality tests are still done on the CPU. The code hasn't been optimized at all yet; the performance is equivalent (+- a few %) on these setups: 1) Phenom x6 1055T, all 6 cores 2) Phenom x6 1055T, all 6 cores, plus a HD6990 using both cores
I don't think the current version is worth releasing. It still needs a bit of work, I want it to be twice as fast. I estimate there is room for a five-fold improvement, especially when I get the primality tests done on the GPU as well.
Tomorrow I will do tests using a slow CPU with lots of GPU power (Sempron 140 with 2x6990).
I think it worth a release... At least we can have pool set up based on the miner.
Yes, I think pool is really important, more than a GPUminer.

Re: Hacking into VPS by originally getting IPs from Primecoin nodes

I think possible when they have your IP and port (opened port)
I get this everytime I start up primecoind --daemon and execute watch -n 5 'primecoind getmininginfo & primecoind listaccounts & primecoind getconnectioncount' 1st problem (during launch) error: couldn't connect to server error: couldn't connect to server error: couldn't connect to server
then I have to go back, and execute primecoind --daemon again until I see this: Error: Cannot obtain a lock on data directory /root/.primecoin. Primecoin is probably already running.
about 10-20 seconds later, the stats show up, and its connected. Do you think this problem could be affecting my possibility to mine blocks? about 2 days ago, I mined 2 blocks in 1 hour.. then nothing the rest of the day, and i am curious if this error has something to do with it? My other server doesn't have this problem, and loads after the first execution of primecoind. Any ideas?
I am using HP7 with directory of /primecoin/src when executing primecoind.
2nd problem (closing down) Primecoin server stopping root@# primecoind stop Primecoin server stopping root@# primecoind stop Primecoin server stopping
I have to use killall -9 primecoind (at twice) to get it to stop. Any ideas to get it back on the right track? 1 server executes launch and stop commands fine, one server doesn't.
1st: primecoind take 100% CPU usage so that make VPS extreme slow, just let it watch, then will be ok. Sleep 5; after --daemon if you want.
2st: Normally it'll stop after 3-5sec, if you can't stop it, reboot the VPS.

Re: [ANN] [QRK] Quark | Super secure hashing | CPU mining | Start is now!
This coin has more problems with the connections than any other coin. I've never seen anything like this.
I've used like 20 other wallets and coins, and Quarkcoin is the only coin I've ever used that won't connect. All the other coins work perfectly.
Don't tell me to addnode the IP's. It doesn't matter if you addnode all the IP's, or try everything. It still doesn't work. And why did you remove UPnP support?
You've messed up something with the networking code that none of the other coins have messed up. I can't get Quark to work on 3 out of 4 of my computers, and I gave up after trying for hours.
If it doesn't sync blocks, or speed was too low, one block at a time. Let's try remove quarkcoin conf folder, re-make conf file, then run from the start. It worked for me.
I've been consistently finding blocks once per day with my Core 2 Quad 9400 OC'ed to 3.5GHz on the second windows client. My pps is usually around 2500, so I'm either very lucky or something is wrong on your end.
Which build are you using, HP5? If so, mind sharing your settings?
Check your PM. Need help asap Now I got 3 blocks and PPS 20 30
Thanks Mikael, I read that it takes a 30 fold increase in processing power to increase difficulty by 1 . . . if so difficult to imagine difficultly ever climbing beyond 12 or 13.
999/(13*13) = 5.9 per block
i thing there are about 1000x optimization left in the code....at least
