Topic: Gridcoin (GRC) - first coin utilizing BOINC - Official Thread - page 253. (Read 597505 times)

what is the difficult of the network right now?

Great, today's best news.

I really hope this fixes the sync issue.

Running it now: v1.1.4.4-g71-prod according to the Help About window (which still says About Litecoin in its header, btw).

I started an instance of cgminer pool-mining BTC first to see whether Gridcoin knocked it out at launch. It did. No big deal. Everything else looks fine, 36437 blocks and "Up to date".

All,

Version 1.1.4.4 is now available for download from the prod MSI.

Alternatively, you can type upgrade from the rpc.

Starting at block 36775 the client will reject stale mined orphans instead of storing them, and we believe this was the root cause of the syncing issues.

Best Regards,
Rob Halford

Reproduced:  You found it!  We are storing a mined stale block that does not validate the boinchash as an orphan; its propogating and getting stuck at the end of the blocks table.  The only workaround is to re-sync.  I think this is the whole problem.  I'll fix this and test now; will release a fix as soon as it is tested!

Thanks for finding this!

Cloud nine, me - I just mined my first block.

I was stress-testing my system at the time, a zillion apps in the background and I was using Rocksmith (a guitar instruction tool) on Steam as though nothing else existed. Suddenly Rocksmith vanished, the Steam window took over with a little notice in the lower right hand corner that Gridcoin had mined a block. Then Windows rebooted! Those are problems for another day though - I mined some Gridcoins (and got the BOINC bonus). All is well. No more stress-testing for a while.     

I'll join the BOINC Gridcoin team and grab 5.8.0 Real Soon Now, but meanwhile I've got to catch up on my guitar practice. Thanks for all the help in getting set up with Gridcoin.

For anyone who had trouble using Upgrade, I just released version 5.80 (Prod version):
-fixes the close of gui miner and cgminer inadvertently
-set this key if you don't want gridcoin to close cgminer/guiminer on exit:     closemineronexit=false
-fixes the bug where you receive an error when you press Create CgMiner Instance
-Full Speed and Half speed work, but still do not have a Memory of their last setting
-Sluggishness problem with cgminer fixed

Good luck,
Rob H.

Deleted - got my facts wrong

Possible bug in Mining Module window (is it OK to report this kind of thing here?). I was checking the "close miner" and "restart miner" button functions. My miner had been running at half-speed (Full Speed box unchecked) because at full speed my cursor barely responds to mouse movements. Close and Restart worked fine, but after the miner restarted, the GPU miner was clearly running at full speed, even though the box remained unchecked. Clicking it twice - on then off - took it back to half speed. I imagine it should come back on restart to whatever speed it was set to when it closed.

The reason I was trying those buttons is that they appeared to parallel the old "Register Mining Module" button pair mentioned in this outdated tutorial: https://cryptocointalk.com/topic/1589-how-to-mine-gridcoin/

Since I have not yet found a block, I was idly checking to see whether I needed to register the miner somehow. I'm still wondering about that part.     

Oh - I was not able to get the UPGRADE to work yet, so this is still the pre-upgrade version. I have not used the RPC console before and my attempts to press Enter after keying the UPGRADE command were ignored - presumably there's something else needed or syntax details I don't know. Perhaps you fixed the problem already though.

I will keep testing this - just got a stale share and I lost sync within 3 units.  I had not added the restartwallet=0 so I will wait to send you the debug results.
I will try the cgminer again and let you know.
But for now, it's off to holiday with the family so no new mining for me - catch you all after the season!

Excellent!

That is very good news.

wonderfull!

CoinPrader,
Great glad you are getting close.  There are about 33 pool miners and I haven't heard this specific problem; I have a fear that if a pool miner creates a stale block, something strange might be happening.  Can you do me a favor--- keep testing with the newest version as some things have been fixed that happen after you mine a block that may change the behavior.  Tell me if you fail to sync now in pool mining mode after finding blocks; ensure restartwallet=0 so you can tell; if it happens, PM me the end of the debug log.

Also, why don't you give the new cgminer version a try, it would be interesting to know if the defaults work for you.  I set them up for 4 machines today and all are working with 3 types of cards.

Ah so - that explains why I could only find tutorials about the projects page in the context of CPU mining. I thought I was overlooking something. Good luck with the feature in any case. Super concepts here.

Hi AiGeezer,
The projects page is temporarily shelved until we know the syncing is over with and the small bugs are fixed.  You can add projects to boinc and receive avg_daily credits for any project; the idea behind the projects page is to bring cpu-only miners in and participate in gridcoin without a gpu; it opens up a lot of issues one being that GPU miners have to provide PoW info in the chain on a regular basis; and its a little too much to support at this stage; but still a viable idea.  One user will supposedly receive 150grc per day doing the cpu mining...  The feature is written but not ready to be turned on due to changes in the block payout structure ( a risk).

Rob H.

Thanks, that's encouraging to see. No, I haven't mined a block yet so I'll keep watching. I got the Gridcoin/BOINC clients talking to each other on TribalBob's advice but that was just a couple of hours ago and then we got an hour-long power outage - big ice storm going on here - so I'll watch and wait for another day or so. My client display now says BOINC utilization 100, which seems promising.

1) The coin wont support itself in the long term if it is not useful.  The exchange rate will eventually drop to zero and they will be removed; look at all the dead coins in the graveyard right now.  
So no one will keep paying for internet resources for something that is dead.
2) I don't think you can create a coin and fool people into buying it on an exchange if its not useful.  DOGEcoin is hugely popular because its novel for pet owners, but look at the exchange rate?  1 billion dogecoins for a bitcoin?  I don't think the Portland programmer is getting rich.  Besides if it gets pumped and dumped there will be no market to sell the coins for any bitcoins; this is baloney.
3) Gridcoin is in a different class than copy & paste altcoins.  The point is all these heat generating devices already exist; if we can put them to use for humanitarian causes and at the same time fight inflation, replace western union money transfer, and provide payment services for web sites then Gridcoin will be more useful than the average coin.  

Eventually the exchanges are going to dump useless coins and keep the top coins, and were going for one of the top 5.

One more thing, cryptographically speaking, we're going to add new features to store relational data in a new format that contains embedded PoW in the actual records so we can store anything in gridcoin.

I just joined your team!
