Gridcoin (GRC) - first coin utilizing BOINC - Official Thread

[lmue]

congratulation that hash rate of GRC now reach 70M.

It's hard to solomine now

If solo mining has become too hard for your hashrate, add the following line to your gridcoin.conf:

Code:

poolmining=true

and then continue as if you were solo mining, this will add you to gridcoin's internal pool system.

It's not stratum or anything like it(it doesn't splits the blocks for pool workers), so it dosn't make any sense  

You don't mine at a lower difficulty, but you will receive a small piece of every block found.

The only requirement  is that you must find a block first to begin receiving payouts from the pool and you must find a block at least once every 100 blocks to stay in the pool or you will be removed from the pool until you find another block as the pool has a 100 block look-back period.

NetworkHashPs:    78581872.00000.
now almost 80M in one hour.

LOL, what a coincidence, I just put up the guide an hour ago...

Yes looks like difficulty is rising too. The days of easy Gridcoins are going away.

I'm not sure of the formula exactly, but basically the higher the difficulty the higher the look-back period is. 100 blocks is only about 4 hours's time and I know before when the difficulty was lower you only had to find a block once a day or so to stay in the pool. I think now it's more like one block every 2-4 days.

You'll have to wait for Rob to comment on the exact formula but basically unless you stop mining you shouldn't have to worry about staying in the pool once you're in and the pool also accounts for all the shares you submit while trying to get your first block. So for example it takes you 5 days to find a block and then you stop mining. You'll get small payments each time a pool miner finds a block for approximately the next 5 days and the total it adds up to should be about 150 GRC. At least that's how I understand it.

If Gridcoin can implement a pay per share system that would be amazing.

how much hard? how much is your hashrate and how many blocks do you find at day?

Yes the integrated pool is dynamic and works good; the lookback is now 8.2 days -- just do a "listminers" and the lookback is the 3rd row, in seconds.

Good luck,

I tried to give this a go last night. It took a while to get the client sync'd but figured that out eventually, then got BOINC installed and working ok.

When I try to run the QT again to try mining, however, it crashes on startup - every time. Any ideas?

[traderman]

did you add the boinc install dir and data dir to gricoin.conf ?

Hmm no, didn't see this in the guide. How do I reference them in gridcoin.conf?

Thanks for your help. 

[aigeezer]

Confirming the issue is fixed on the newest version by deleting "c:\programdata\boinc\gridcoin.dat" and restarting gridcoin

I can confirm this too (sorta).       

First a minor quibble - my pathname didn't use "C:" so the file to delete may or may not be on the C drive.

More interesting - I had not been getting the 50% problem until today, and this change did indeed fix it, but on restart I got a black screen briefly, presumably when the miner started, and a Windows message that the graphics driver (AMD Catalyst 13.9) had stopped working and recovered, followed by a message that the miner had encountered an error and Windows would close it. The Restart Miner button seemed to fix things, although the Full Speed checkbox toggle did not seem to work at first (a problem that had been fixed a while back, but may have returned).

All in all, everything seems to work again.

Nice catch on the 50% problem - that couldn't have been easy to find.

It wasn't referenced in the guide because the guide says to install BOINC in the default location, if BOINC is installed in the default location you do not need to reference them in gridcoin.conf

If you installed BOINC somewhere else you will need to reference BOINC's directories. The instructions on how to do so are somewhere in this thread, I will find them in a little bit and add it to the guide.

***EDIT***:

If you install somewhere besides the default directory you will need to add these lines to your gridcoin.conf (replace the file paths with the correct location of where you chose to install):

Code:

boincappfolder=C:\Program Files\Boinc\
boincdatafolder=C:\ProgramData\Boinc\

The guide has been updated with this info as well.

[asdlolciterquit]

I think we need a comprehensive instruction manual or some kind of video tutorial for the new people.

I'll do it, will post it and link to it from this thread here in an hour or two...

thank you so much. Pls, explain also how get 100% boinc on gridcoin..

100% CPU utilization for boinc + min. 1000 average daily credits.

how many hours at day?

In my case the problem was twofold - default install directory is "Program Files (x86)" on a 64 bit Windows system, and I'd changed the data directory too.

Unfortunately the QT still crashes when I start it.   Edit: splash screen is "Loading wallet" when it crashes. Going to bin the Gridcoin data directory and start again!  
 

[derm]

mine crashes too,
upon trying to send 1 GRC in win7 64bit the wallet terminates stating:
"MS Visual C++
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information."
Retry @ 1 mGRC failed as well.

is there already a pending request to integrate some stable version of boinc?
this might strip dependencies and make the system less vulnerable.

Are you certain you pointed to the correct BOINC directories in your gridcoin.conf and you didn't just copy

Code:

boincappfolder=C:\Program Files\Boinc\
boincdatafolder=C:\ProgramData\Boinc\

For example, if you installed BOINC at D:\BOINC then your gridcoin.conf should say:

Code:

boincappfolder=D:\BOINC

100% certain. Can only imagine wallet.dat was corrupted so have deleted Gridcoin data directory, including blockchain (doh) so am now trying to re-sync. Annoyingly, I'm now back to no connections to the network. Have added the addnodes and sorted port forwarding as described earlier in the thread. Any ideas why this connection problem persists for some users?

Hmmm, very strange. Things to double-check:

1) Make sure you are running Gridcoin as admin
2) Make sure you have forwarded the correct port as this port was changed a couple weeks ago. The correct port is "32760"
3) Try adding an exception rule to your firewall for Gridcoin

if i see something like that on my cgminer (i use an external istance of cgminer), is it correct?

No suitable long-poll found for http://127.0.0.1:9332
network diff set to 2
new block detected on network
network diff set to 2
new block detected on network

and so on...

Yes, that is the correct output, later versions of cgminer have a slightly different output format than the earlier versions which is why it doesn't look "familiar" if you were using an earlier version of cgminer before...
