Alas the ztex code is in complete bitrot. The only code maintainer for it (nelisky) has long since disappeared and made no attempt to come back and maintain or bugfix it. So you're screwed.
meh...
But ok, at least i know where i am standing. Thanks.

Maybe "cure" will be compile "GPU-only" and "FPGA-only" versions? And run 2 programs?
Thats what i try to accomplish not to have: I would love to have my miners in one single program.

Nice, but it doesn't actually achieve any demonstrable performance advantage.
You know something? You are quite right! We can write off all of this saga with a "human tries to beat compiler again"! 
Out of curiosity, I went to dig deeper on how AMD would do branch prediction (it doesn't), but it does branch predication for branches with few ops!
Basically, the instructions inside the if branches are only executed based on a comparison result (they are not done in paralell), each op inside gets a true/false predicate flag for execution. So the most efficient code for this part is simply removing the main "if" (using the phatk v2 example):
Code:
#elif defined VECTORS2
if (!W[117].x)
SETFOUND(W[3].x);
if (!W[117].y)
SETFOUND(W[3].y);
Each of the if(!...) starts with something as:
1351 x: PREDE_INT ____, R0.x, 0.0f UPDATE_EXEC_MASK UPDATE_PRED
for updating the predicate flag
This means that if no nonce is found, the most common path, the penalty is only the execution of two PREDE_INT ops, with zero misfires for false positives (min path has the same exec time as with bitmasking). This also allows for simultaneous nonces in both vectors and allows for the nonce itself to be all zeros. Check the GPU ISA code, the execution path is clearer there!

I think I got your point, now. Thanks again.
You're welcome, it's always nice to have someone for debate!

There seems to be a severe bug with 2.8.3 and ztex FPGAs.
I was running my ztex on 2.8.3 a few times always with the same result. After a random amount of time (ranging from 10min to 10hrs for me) the ztex only produces "hardware errors" and my gpu is only running at 100% with no shares produced (or send to the pool?). Also CPU goes up to 100% basically leaving my system unresponsive until cgminer is stopped hard.

Yes but that would make my 2.722 Gh only appear as 2.7GH which is not accurate enough. Significant digits is the key.
I've created a (unnecessarily complex) workaround and committed it to git so it's always padded on the right by zeroes. I agree it looks better. October 16, 2012, 05:00:20 AM
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?"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%.
That was not the question I was answering. My question was "What is the probability of finding k nonces at the same time?"
I think that, thanks to your patience, now I see how you approached the problem.
I wouldn't say "at the same time": Poisson distribution tells you the probability that an event happens N times in a fixed time interval (or in a fixed space interval) when you know that the mean in that period is lambda. So with Poisson you have first to choose an interval, and then go on. It can be as short as a... wavefront, or the clock of your hardware, I don't know how to say it well. You chose a hash computation time as the interval, of course.
Quote
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?
Oh, ok! I'm sorry to say that I don't know how hardware and software work, so please forgive me for my past assumptions. :-p
The problem is: "every n clocks, we don't care about n, we have our bunch of exactly X simultaneous hashes, all toghether in a wavefront, given by our X concurrent threads (I hope that "threads" is the right word here). Each thread gives us one and only one hash. Since we know that the probability for a hash to be a nonce is 1/2^32, how many Y nonces (with 0<=Y<=X) are we likely to find in a bunch?"
Well, then Poisson is not the most proper distribution for us: it isn't meant to describe this situation.
AFAIK Poisson is thought to calculate the probability of a number of sequential events in a fixed interval. You are using it to calculate the probability of simultaneous events in... no interval.
Using Poisson completely confused me, and led me to guess a different situation and a different problem. I'm sorry for that.
Of course Binomial is the proper distribution, but you're completely right writing that Poisson gives a very good approximation, as you showed, setting lambda = X/(2^32). So Poisson is numerically right, too, for our case.
I think I got your point, now. Thanks again.

that is the last output from debugging after the miners dieded last night.

so it seems it has todo with stratum and win32.

that is the last output from debugging after the miners dieded last night.
The machines with miner 2.8.3 - win32 and started with --fix-protocol didn't die.
so it seems it has todo with stratum and win32.

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

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