Turkiye'ye hos geldin.  

You guys really are desperate to believe there will be a war with Iran.  

There is a fair chance Barack Obama will win in November.  But that chance falls to zero if he goes to war with Iran.  Iraq cost 4500 lives and over a trillion.  Iran is over 4 times the size, it has been preparing for invasion since 2003 and the place is huge.  The notion that a country that can't defeat a ragtag militia in Afghanistan will suddenly find the stomach for occupying a huge well armed country is laughable

Think about it.  Are you really thinking that any Presidential hopeful, let alone a frail plant like Obama, would go to the US public on a track record of 18,000 extra combat deaths and an extra $4 trillion borrowing to finance it?  No way - it won't happen.  

If there is a military intervention, it will be well after the US elections.  Anyone telling you otherwise is nuts.

An invasion and occupation of Iran isnt going to happen. Attempting it would make Vietnam look like a cakewalk. That doesnt mean there will not be a war. Similar to the Libyan war, or at least that might be the plan (ie, airstrikes).

In many respects that war is already on; the west is already blowing up stuff in Iran, violating Irans airspace, assassinating scientists and political leaders, funding terrorist within Iran and the latest round of US sanction, if fully implemented, are nothing short of an act of war. The only question is if Iran will react. While its hard to defend the Iranian regime in the broad sense, I will credit them for restraining themselves and being completely reasonable so far in their international relations.

You can also try disabling everything you dont need in the bios, like floppy, firewire, audio, etc.

You can try killing cgminer with

Code:
sudo kill -9 <pid>

Or reboot the system in the not-nice way with

Code:
sudo reboot -f

I'm thinking this may all be related to my donation pool being flaky lately with the move and nothing to do with the new version.

In support of that theory: I only had one instance of the connection bug so far, and that was when I turned on donations and happened more or less simultaneously for two instances of cgminer. I turned donations off again and have been sailing smoothly since New Year's Eve (which is when the bug occurred for me).
Anyway, I'm back to donating manually.

On hindsight I think the problems began when I enabled donations as well. How ironic, donators being 'punished'. Ill turn it off as well and see what happens.
1730  Bitcoin / Hardware / Re: Pictures of your mining rigs! on: January 04, 2012, 03:27:27 PM
Temperature variation is the real card killer.   I'd agree with anything < 80-85C, but some cards just don't stay that cool even standing alone with good ventilation and room-temperature ambient environments.

It's more important to make sure your temperatures aren't swaying significantly on a regular basis, the (small) expansion/contraction will eventually stress the metals in your GPU, leading to reduced life.

A stable 80C is far better than swinging between 60C and 80C every day.

This isnt quite true. Heat cycling is a small risk for haircracks in solder and underfill. This problem has become well known when a batch of nVidia cards suffered from a manufacturing deficiency that made them extremely vulnerable to this. These are the cards you can usually "fix"by reflowing them in an oven. This is something that pretty much never happens with AMD cards.

High temps otoh increase electromigration. Electro migration can be thought of as "internal wear" inside the chip. Its what over time leads to lower overclocks (if transistors in the critical path are affected) or instability and plain old dead cards. This is far more frequent, particularly with mining cards. Electromigration is a function of heat and the relationship is exponential.

1731  Other / Off-topic / Re: Abolish the Minimum Wage Law on: January 04, 2012, 08:09:10 AM
Lowering minimum wages is a brain dead idea; it will not increase employment levels and will in fact further ruin the economy. The problem most corporations have is not primary labor cost, its a lack of consumer demand.  You could go back to slavery and it wouldnt solve that problem. On the contrary, lower minimum wages will further decrease the money consumers have available for spending.

IMO income and wealth disparity is not a social or "fairness" problem as much as it is an economic problem.
1732  Economy / Speculation / Re: the real price of 1btc on: January 04, 2012, 08:00:01 AM

Quite true. If a miner spends $1 creating a bitcoin and can only sell it for $0.01 it only stores $0.01 of value, ie the demand value not the production value. Thanks for pointing that out.

However if price jumped, less people would mine, difficulty would go down, the amount of electricity required would be less, and the price to create 1btc would eventually roughly even out... which makes me think that still electricity is a reasonable estimate of the minimum price of a bitcoin.

You have that backwards. The exchange rate of bitcoin divided by the production cost (mostly electricity for now) determines the total network hashing power and therefore, the difficulty, not the other way around.

If you have any doubt on that, just look ahead; the amount of coins generated through mining is cut in half every 2 years and eventually approaches zero. How will it impact the price? It wont. But unless transaction fees become much bigger by then,it will have a tremendous impact on difficulty and hash rate.

Fan bearings will wear out sooner or later. I strongly suspect the relationship with fan speed is at least linear, possibly super linear as vibration is likely a very important factor (avoid speeds which produce more mechanical noise, humming etc).

Of course you can get lucky. Or maybe that poster has some advantages most other miners do not, like a dust free environment or he lubricates them regularly. Either way there is little doubt in my mind a fan at 100% wont last as long as one on 50% and its not like fan failure is a rare thing. Its equally true low temps will help the card live longer, but it all depends how high your temps are. I get <60C with fans at 50% (non ref cards), its pointless to increase fan speed in those circumstances.

There was a bug that would cause higher rejects with multipool setups that was fixed in 2.1.0. We're only turning LP off at the moment to debug a network connectivity issue.

The network bug has been there for me since 2.0.8 at least, possibly longer. Its not new in 2.1.0
1735  Bitcoin / Mining / Re: Offline mining? on: January 03, 2012, 09:37:15 PM

Yes.  I am not sure of the exact computational power of the machines I am interested in using.  It actually may be a very poor estimation because I am guessing based on petaflop output which, to my knowledge, is more or less irrational.

Regardless, it's a shit-ton of power.

FLOPs are floating point operations. If you can get access to a supercomputer thats any good at flops, it will almost certainly stink when it comes to sha256 hashing (integer). A typical TOP500 supercomputer may have trouble delivering higher hashrates than your typical 3x dual GPU mining rig.

Okay slight exaggeration perhaps, but not much; the top 250 supercomputer uses 12K xeon cores, which would roughly produce 12GH/s. Thats still only as good as ~6 good mining rigs.
1736  Bitcoin / Mining support / Re: 30+ Mhs drop adding a second card on: January 03, 2012, 08:42:14 PM
Can you try another miner to rule that out as possible cause? Cgminer or bitminter?
1737  Bitcoin / Mining software (miners) / Re: CGMINER miner overclock monitor fanspeed RPC in C linux/windows/osx 2.1.1 on: January 03, 2012, 08:36:42 PM
Mine have worked for weeks without problems, or at least without me noticing. It seems to be happening more and more often now.

Anyway, lets see if we can find anything else in common, besides just cgminer.

- Im using google DNS
- I have donations enabled. (thinking of disabling it, just for testing)
- I have several pools configured in fail-over (but Ive since encountered the problem on several different pools)
- Im behind a NAT router
- hmm?

Ive already ruled out OS and AMD driver versions as its happening on both windows and linux machines here with various drivers and cgminer versions.

But once this 503 conditions starts, cgminer will never (*)  resume working correctly until restarted, even though there is definately nothing wrong with my lan or internet connection at that point (and I suspect there never has been, but who knows).

As for different miners, yes I tried bitminter and not had issues with that.

(*) actually, if I saw it correctly, cgminer will occasionally submit valid shares for very short periods of time.

Last night, cgminer had pool connection issues during the following intervals:
00:10 - 00:12; duration 2 minutes
03:52 - 04:31; duration 39 minutes
06:55 - 08:05; duration 70 minutes

A problem interval is from the first "not responding!" to the final "recovered" with at most a dozen or two "accepted" between communication-related outputs.

At this writing, 09:25 it's been running normally for 80 minutes.

In sum, at least for its current session, it does seem to resume working correctly.

Interesting.
And I may have had the same here; there have been mornings when I checked hashrate and it was surprisingly low. Probably because of that error. When I caught it "live" I  never waited 70 minutes, so you are probably correct that at some point it may recover, I just never waited long enough.

Does bitminter use phatk? The other miner I used also used phatk.

I dont think so, I believe DrHaribo handcoded the whole thing.

Is anyone interested in me making some changes to 3 programs and setting up a pool:
Adding a socket interface to bitcoind, a pool (whichever one I or someone else decides) and cgminer.
I also suspect it may resolve a long term issue of pool performance.

Id be interested and wouldnt mind throwing one or two videocards at it during testing, but in the long run, assuming it does provide some benefit, I would like to see this in other pools as well.

Its certainly possible my internet connection isnt 100% perfect, and something flaky may trigger it, but it doesnt explain cgminer's behavior. It should just continue working the moment the internet connection is restored. And it actually does that when I eg unplug the network cable. After plugging it in again, it resumes working as youd expect. Same when my ISP went down for an hour some weeks ago. It didnt require anything for me to get cgminer to start working again.

But once this 503 conditions starts, cgminer will never (*)  resume working correctly until restarted, even though there is definately nothing wrong with my lan or internet connection at that point (and I suspect there never has been, but who knows).
