It's the so-called Golden Week in China, a 7 day national holiday. ngzhang is probably chilling with his family right now.

I too am waiting for Lancelot and also matthewh3's "mystery" board that he has not revealed for ages now.

Don't you know that releasing something in May generally means releasing it on the 31th of May earliest? 
May 01, 2012, 02:41:22 PM
It's May.

Its not May yet. 
I for one can't wait.

Nice job ngzhang. Those who got in on batch 4 are lucky. Hey I'm wondering though when you're going to release details regarding your next project. Are you moving towards a quad FPGA setup?
Yeah, what the status of lancelot???

batch 4 reduced power consuming to about <19W at full load with fan (boards input). 
i tried some hi-end MOSFETs.
details:
IDLE: 3.1W(with out fan) / 4.1W (with fan)
FULL LOAD: 17.2W(with out fan) / 18.2W (with fan)
all boards input.

pretty neat!

It is working but not too stable for me with win7. I had 2 BSOD (bluescreen of death) in a row. I had to switch back to MPBM.
I'm in win7 for now and had 2 bsod, one with cgminer 2.3.3 and ozcoin(bad pool header), default miner.py does not even run @ozcoin
and on some random I forgot the bsod message
Never tried the stock miner. Try MPBM. Works very well with ozcoin.

I can report I've got 6GHash of icarus boards now mining against P2Pool happily with low stale rate. (can be seen live at www.btcsyn.com)
I'm using MPBM (testing branch) to control them.

The requirements to effectively use FPGA on P2Pool are that they do at least one of:
A ) Report shares as soon as they are found
B ) Allow a nonce-range to be processed instead of the full range
C ) Can abort work
A ) Report shares as soon as they are found
B ) Allow a nonce-range to be processed instead of the full range
C ) Can abort work
Ztex does something very close to A (there's no interrupt to state a share was found, but it will be reported on poll which we do constantly) and aborts work as per C.

Hi, did someone allready tried the icarus board with p2pool? It seems that not all FPGA boards are p2pool compatible (at least the rumors say something about xtec).
...
The requirements to effectively use FPGA on P2Pool are that they do at least one of:...
A ) Report shares as soon as they are found
B ) Allow a nonce-range to be processed instead of the full range
C ) Can abort work
D ) Can poll share status (close to A ) but does waste on average half the poll time per share)
Of the 4 above, A ) and B ) are the best.
If an FPGA only does C ) then you are still wasting a lot of work, but not as much as an FPGA that does none of the 4
I have no idea if any FPGA supports B ) yet.
Icarus supports A ) and C ) so any software that takes advantage of them both will be best to use on P2Pool
BFL only supports C ) so far.
Ztex supports C ) and D ) so thus would also be OK for P2Pool
I have no idea about the others yet.
I think they all support C ) and without C ) it is also pretty bad due to wasted work after an LP happens
(i.e. the point about P2Pool is it has 60 times the number of LP's as a normal 1 difficulty share pool)
Edit: Updated with "D )" and Ztex

Allso i would like to know if industry or commercial standart spartan6 was used for the icarus board :)
