I used the new 2.8.3 and its noticeably slower for some reason. My Mhash is the same as 2.7.5 but the the accepts shares are like significantly less. I usually do about 600 shares an hour with this im doing 120 shares

Do you have higher difficulty?
If you use stratum protocol and your workers give too much hashes, the pool increases difficulty for you, so you have less shares but get paid better per share.
CGM shows that in the shares line.

I'm using 2.8.3 with Linux.
I mine on many pools, and I do hop on some of them, having the others as backups, so pool switches are common here.
My only stratum pool is Slush. I have it in my configuration file as:
Code:
"url" : "http://api.bitcoin.cz:8332"
so I leave it to cgminer to recognize ad activate the stratum protocol, which it does:
Code:
Switching pool 7 http://api.bitcoin.cz:8332 to stratum+tcp://api-stratum.bitcoin.cz:3333
But after a few hours that cgminer is running, I always find this stratum pool as "Enabled Dead".
While mining on another pool, in the log I see things like:
Code:
[2012-10-15 01:31:50] Pool 7 http://api.bitcoin.cz:8332 not responding!
[2012-10-15 01:31:51] Pool 7 http://api.bitcoin.cz:8332 alive
but, checking immediately after that, in the Pools section the pool is showed as "Enabled Dead", and it will remain dead forever. As soon as I restart cgminer, the pool is alive again (so it's not a pool problem).

I don't know if it happens every time the pool doesn't respond for a while, or whenever my box changes its IP address. I'm just sure it happens at least every few hours.

HTH.
I noticed this also when I used BTC Guild as a backup for a while. I just assumed they were sick of me using them for detecting new blocks sooner without actually giving much work back; I had just as many getworks with them as I did with my primary pool. Tongue

 I haven't seen this myself but there could well still be a bug in there. I'll keep auditing code.

This is what I don't understand too well (sorry to bother you).

Let's assume, as you wrote, that your device has 1GH/s of computing power.

So what T do you like to choose?

If you choose T=1 sec, then the probabilty to find one nonce in T is the mean, so is lambda. Lambda is 1/4.3=0.23. 23%.
The probability to find two nonces in T, according to Poisson distribution, is ((0.2325^2)*e^-0.2325)/2!=0.021. 2,1%.
Depends on what question you are trying to solve. The question you answered above is "What is the probability of finding k nonces in a period of 1s? And in a period of 2s?"

That was not the question I was answering. My question was "What is the probability of finding k nonces at the same time?"

If you choose T=1/1E9 sec, AKA the clock tick duration of your device, then I calculate the probability to simultaneously find two or more nonces this way:
a) if your device processes hashes sequentially (one thread), of course there cannot be simultaneous nonces if we consider T=1/1E9 sec =1/(GPU hashes per timeframe);
b) if your device processes more than one hash simultaneously (more threads), there can be simultaneous nonces, but every thread uses just a part of the device computing power. Let's say we have five threads. Each thread is capable of 200MH/s, so it finds a nonce in about 21.47 sec  (that is: 2^32 H / 200MH/s). In 1/1E9 sec each thread finds a mean of 1/21.47G nonces.
The problem is independent of thread execution time, because that is relatively constant. They all end at mostly the same time in a wavefront. The problem is: when they all end, how many have nonces?

The probability that at least N of our five threads find a nonce in the same clock is 1/21.47G^N. We can say zero, and we don't need any Poisson distribution for it.
When n->inf and p->0 the Poisson follows the Binomial, so either gives the same results: https://en.wikipedia.org/wiki/Poisson_limit_theorem

I can rewrite everything in another way, using another example:
Code:
Assuming each wavefront composed of 256 threads with 2 vectors each:

lambda = 1/(2^32)*256*2
Poisson(k) = (lambda^k)*(exp^(-lambda))/(k!)

Probability of finding 1 nounce in a wavefront:
P = Poisson(1) = 1.1921e-07
P = Binomial(1, 512, 1/(2^32)) = 1.1921e-07

Probability of finding 2 nounces in a wavefront:
P = Poisson(2) = 7.1054e-15
P = Binomial(2, 512, 1/(2^32)) = 7.0915e-15
Either way we look at the problem, the answer is always the same: the probability of finding 2 nonces at the same time is 10^8 smaller than for finding 1 nonce! In another words, a ~0.1 Exahash/s hardware will find 2 nonces simultaneously at about the same rate a 1GH/s card finds 1 nonce right now. Grin

I've noticed that the GPU core temp is no longer being displayed on the output from version 2.8.3 for my 5850 on Win7x64.  Previously when using 2.7.6 and before it was outputing GPU temps. No change in SDK/Driver, the only change was the cgminer.exe binary.  I looked over the config, and nothing looks too different -

What am I missing in order to output/log GPU temps?

Just updated to 2.8.3.  I have to say I really don't like the new precision on numeric output:

Quote
GPU 0:  73.0C 2900RPM | 604.2M/661.2Mh/s | A:3 R:0 HW:0 U: 7.03/m I: 9
GPU 1:  74.0C 2912RPM | 595.1M/659.3Mh/s | A:5 R:0 HW:0 U:11.72/m I: 9
GPU 2:  74.0C 2922RPM | 611.8M/658   Mh/s | A:10 R:0 HW:0 U:23.44/m I: 9

Could you put a .0 on there instead of all that blank space?  It's a minor thing, but I like it better that way.
This is a side effect of trying to find a generic format that is aligned on the screen and fits values from 0 to 18,446,744,073,709,551,616 in a generic way, while still maintaining adequate precision for the relative rate for that device. It is not entirely straight forward and what to do about zeroes is not ever going to be to everyone's satisfaction. 001.0 or 01.00 or 1.000 ?  

By the way, that massive value would show up as 18.45EH/s with that current scheme, so that it could show up aligned on the same screen as something with 0.001 H/s.

Thanks - I figured as much.  The units allow you to have a maximum 3 digits on the left side, though, so you could simply lay it out such that there is a space-padded 3-digit integer part and a 1 digit decimal part all the time, no matter what, meaning:

Quote
604.2M/661.2Mh/s
595.1M/659.3Mh/s
611.8M/658.0Mh/s

In my case, and using your example:

Quote
604.2M/661.2Mh/s
595.1M/659.3Mh/s
611.8M/658.0Mh/s
 18.5E/ 18.5Eh/s

Yes but that would make my 2.722 Gh only appear as 2.7GH which is not accurate enough. Significant digits is the key.

Don't forget modern GPUs have up to 2048 shaders...
Thanks! Grin So, refactoring...
Code:
Assuming a worst case scenario, with each wavefront composed of 2048 threads with 4 vectors each:

lambda = 1/(2^32)*2048*4
Poisson(k) = (lambda^k)*(exp^(-lambda))/(k!)

Probability of finding 1 nonce in a wavefront:
P = Poisson(1) = 1.9073e-06
P = Binomial(1, 8192, 1/(2^32)) = 1.9073e-06

Probability of finding 2 nonces in a wavefront:
P = Poisson(2) = 1.8190e-12
P = Binomial(2, 8192, 1/(2^32)) = 1.8188e-12

So, if they all end at the same time (or during the non-atomic mem write op), for every ~1.000.000 found nonces you'll throw one away (overwritten). If using vectors 2, every 2.1e6, and vectors 1 every 4.2e6.

On a 1GH/s card, where finding a nonce takes about ~4.3s, it will take around 50 days of 24/7 runtime for the vectors 4 case to happen once. Smiley

That's still only accounting for the simultaneous nonce problem, not the similar bitmask or zero bitmask cases. You certainly make a good argument for not using atomic ops.

No bitmasking needed, the C "?" operator has a specific GPU ISA op code. Smiley

Nice, but it doesn't actually achieve any demonstrable performance advantage.

Code:
[2012-10-15 01:31:50] Pool 7 http://api.bitcoin.cz:8332 not responding!
[2012-10-15 01:31:51] Pool 7 http://api.bitcoin.cz:8332 alive
but, checking immediately after that, in the Pools section the pool is showed as "Enabled Dead", and it will remain dead forever. As soon as I restart cgminer, the pool is alive again (so it's not a pool problem).

I don't know if it happens every time the pool doesn't respond for a while, or whenever my box changes its IP address. I'm just sure it happens at least every few hours.

HTH.
I noticed this also when I used BTC Guild as a backup for a while. I just assumed they were sick of me using them for detecting new blocks sooner without actually giving much work back; I had just as many getworks with them as I did with my primary pool. Tongue

 I haven't seen this myself but there could well still be a bug in there. I'll keep auditing code.
Found it, thanks. Will be fixed next version.
