i must say this stuff is stable. during a bad network condition, no fault appears. the stale rate is about 3%.

now the nonce is transmit from high to low byte. if you need a byte inverse after received them, i think the off-set value must be add to the inverted nonce.

Try adding http:// to the url, it doesn't recognize it as an url. Currently there is no validation of input parameters, that code part was added in a hurry to be able to share a first usable edition. But still, you found the first bug, it should abort on MalformedURLException because further tries won't ever succeed. Default behaviour is to try for ever to make sure it starts working again after networking problems occured.
Multiple boards with one miner instance and LP are on the todo list

.
I'm not sure about scanning the ports though, I wouldn't want a miner to automatically write to all my serial connections. But something like a startup flag would probably be fine.

i just add a "http://" but looks like no use... maybe deepbit is a little different? BTW, i'm using windows7 64bit.

an additional beg: is it possible to add a valid nonce offset parameter to the program as a debug function? it means add or subtract a constant value to the calculated nonce. this will help me a lot on the debug flow.

thankyou~

...

Hm seems I have to look into that deeper. Did the error message change after adding 'http://'?
About the nonce offset, I can add this. Right now I inverse the nonce as soon as I receive it (the displayed value in the log/console is also already inverted). Does the offset have to be added to the inverted nonce or to the nonce as it's received?.

Looks like I'm gonna jump on the FPGA bandwagon too. Just placed my first order today. Hope everything goes smooth.

Question for ngzhang (apologies if it's been asked before): Can the dev kits be ordered separately? Or they must be bundled with a FPGA board?

i replayed your mail, and certainly , the Dev kit can order separately (with the same price).

it's certainly will be better if it can auto scan whole com port (using the dummy midstate&data), support multi-boards with one miner instance, and long pool...
maybe i'm tooooo greed. Grin

good work!

If someone wants to test the miner I'm currently working on, I prepared a litte prerelease for testing purposes. I'm using it to mine since about 12 hours now. PM me and I send you a copy (I don't currently have any hosting ready where I could put the file). The miner is written in java and should not be affected to much by a bad network connection. Long polling is not yet supported but it's the next thing on my list. I probably release the miner as open source when it's ready. Feedback is highly welcome

.

Why not host it on Github?

Hm not sure if that works. Github is free for open source only, and I'm not ready yet to fully release it.

I expect all new products to have problems
and brought icarus to test fpga mining and the product
and 1 X 380 mh/s miner locking up is not a problem at all - so take your time to fix it

in next 6 months I want to get rid of my all GPU's based miners
and buy about 200 fpga based miners

it's certainly a problem. and present working is around the miner software.

For what it's worth it's been my experience that BTCGuild has been the most stable with the least number of rejects of many pools I've tried (by a wide margin too such that it's even worth the fee). You may want to test pointing your hashing there and see if it works better.

oh, that pool is very unstable here. you know I'm in the Great Fire Wall. now i'm using ABCpool.co

Oh. Weird. I figured since I was in Thailand it ought to be even more stable for others. I think our data mostly goes thru Singapore so maybe some other routes are worse. (We have a crazy number of hops before it even leaves Thailand.)

Thanks for the update

since the miner stuck is a known issue -- there is no point in me changing pc or trying another mining pool

i will wait till you have a fix

Luke

by my plan, miner software may change in this month. before that, a watchdog timer may add to present miner to solve this problem as a temporary solution.
a experience is , if your pool is stable, the miner stuck may rarely happens.

let's discuss about the pool selection.

in brief, if you have a large ping, please use the queue version of the miner software, but it will cause a higher stale rate. about 1-2%. but the FPGA could run at a full speed.
but if your connection is unstable, it has already been found that both miner software sometimes get stuck.

the both simple and queue miner will not continue or fix. we will change to a more common use miner, like CGminer or some other stuff who want to support icarus. there are already some people working on this.

Quote

I'm sure it hasn't yet. My question was more a what if scenario aimed at understanding the dependence between the FPGAs. If one were to be damaged/abused how would the other one be affected. If one gets sick/dead does that render the other also inoperable? I'm not saying anything is wrong but it's good to understand how they relate to each other. From looking at the code it seems like the first dead would knock out the second, but not the other way around; unless I'm wrong about how the second communicates via the first.

hmmmm, the FPGA simply act as a wire. pass the host data to the next one, and store-and-forward data to the host.

I have changed to queue miner and now get 374.25 +/- 5.93 MHash/s

I also get "upstream result: False" about every day and the mining stops --- I throught it may be my pc -- so I am in process of setting up a new pc to run software/icarus

I will run some traceroutes and ping test and post results and respond to ecki

the "upstream result: False" means stale, or just a wrong data.

Hello Hardpick,

how important is ping time?
I am getting 360 mh/s from 2nd batch icarus on deepbit which has a ping time of 410 ms
(my isp ping time is 11ms -- have adsl2 at 12.34 mbps/ 0.83 mbps -- I live in sydney australia)
I have tested other pools
...
ecki.net.-----361ms
...

361 ms from Australia to Thailand? This is very bad... Sad

Which Internet Provider do you use? Telstra?
I have less than 200ms to my customers in Sydney from here (Thailand)... so it is the same distance!

Ping-Statistik für 203.37.115.162:
   Pakete: Gesendet = 4, Empfangen = 4, Verloren = 0
   (0% Verlust),
Ca. Zeitangaben in Millisek.:
   Minimum = 184ms, Maximum = 190ms, Mittelwert = 187ms

Could you PM me your traceroute to miner.ecki.net please?
Note: NOT ecki.net, because this will be in Germany and not Thailand where the pool server is located!

The ping time is important, but the variance is also very important.
The difference between Minimum, Maximum and Average should be as little as possible!
But most important for mining are the number of packet drops!
So just ping the target 10000 times and have a look about the % of packet losses.
Ping is important, but it is not all...
If you have a high number of packet drops to your current pool, then choose another one and it will increase your current hash rate of 360 MH/s!

For more answers or information about network questions please PM me, this is off topic here in this thread (I assume)... even you are using an Icarus board.

Cu,
Ecki

Hi Ecki
Thanks for the help
I have changed to queued mining and now get 380 mh/sec --
only problem that need to be resolved is miner lockup (I am in process of changing PC - if this does not resolve problem will then try other pools)

I no longer think ping time is a problem unless it is causing the lockup

-Let's say that in theory, I have a motherboard with 8 USB ports and 4 PCI-Express slots. So, always in theory, I could plug 8 FGPA board and 4 GPU in that motherboard and they could all mine together, correct?

You can use USB hubs and additional USB controllers too.

In THEORY, you could have 127 USB devices per port. But again, that is just THEORY.
The speed will be so slow that hashing would probably stop.
