Great job!!

Marc, have you considered making NR_ROWS_LOG fixed at 20, and clearing cnt for each round?  Then each row would have only collisions at each round, avoiding the need to search for collisions.  Then NR_SLOTS/OVERHEAD could be significantly reduced.
To avoid time penalty for clearing the cnt values, instead of calling kernel_init_ht at each round, you could zero the count after checking the row.  When the DRAM page is already open to check the cnt value, the time cost of doing a write back to the same page (in fact, same 64-byte cache line) is minimal.

Yeah NR_ROWS_LOG is pretty much always compiled at 20. But I have to offer the other options because people want to mine with GPUs having very little memory. And I don't know if you checked the latest commits, but OVERHEAD has been lowered to 9 so 1 Equihash instance needs only 1.2 GB, and I recently made the exact change you suggested (clearing the counter after we are done using/reading it).

I think the vast majority (>95%) of miners have cards with at least 2GB RAM.  The kernel I designed (and only implemented a bit of prototype code) is quite similar to yours, but only supporting 2^20 sorting bins (or rows).  My design has 2 tables like yours (I consider it to be like double-buffering), but I hadn't thought of dividing the saved indexes between the two tables so they could fit in 28 bytes and leaving 4 bytes for the collision counter.
I did see the change of OVERHEAD from 13 to 9, but I hadn't noticed the counter reset at the end of the round.
https://github.com/mbevand/silentarmy/blob/master/input.cl#L568

Since you say you have to support options other than 2^20 rows, I'll probably fork your code and optimize it for 2^20.  I think it should give another 10% performance boost.  I also think even more performance can be attained by optimizing for the 256-byte stride size of the Polaris, Tonga, and Pitcairn GPUs.  Despite your comment in the code about odd values of OVERHEAD being best  for avoiding channel conflicts, I had found 12 was faster than 13 in my testing on Tonga and Pitcairn.

i have installed silentarmy, no error with compilation but i have this result :

# ./silentarmy
Traceback (most recent call last):
  File "./silentarmy", line 542, in <module>
    main()
  File "./silentarmy", line 539, in main

    asyncio.ensure_future(self.reconnect())

[greaterninja]

I'm guessing you are using ubuntu 14.04 or a older version of python 3.4x.

remove the installation directory and all files

Code:

rm -rf silentarmy

then rebuild it.

Code:

sudo add-apt-repository ppa:fkrull/deadsnakes -y
sudo add-apt-repository ppa:chris-lea/libsodium -y
sudo apt-get update
sudo apt-get install -y python3.5 libsodium-dev
git clone https://github.com/mbevand/silentarmy
cd silentarmy
make
sed -i 's/python3/python3.5/' silentarmy

then see if it runs by typing

Code:

./silentarmy --list

OR

Code:

./silentarmy --use 0,1,2,3,4,5,6 -c stratum+tcp://us1-zcash.flypool.org:3333 -u twalletaddress.WorkerName

If you have 2gb card use

Code:

./silentarmy --instances 1 --use 0,1,2,3,4,5,6 -c stratum+tcp://us1-zcash.flypool.org:3333 -u twalletaddress.WorkerName

Credit mainly goes to n1koo for the fix/workaround.  His response is here https://gist.github.com/n1koo/7c0455b674d3c3a9d4cccf53837b270e

RTFM:
"(beware: the silentarmy miner makes use of Python's ensure_future() which requires Python 3.4.4, however Ubuntu 14.04 ships 3.4.3, therefore only the sa-solver tool is usable on Ubuntu 14.04.)"

thanks for your response.
but it don't work

I am using ubuntu 14.04 on my 4GPU rig (3x radeon 280x and 1 270)

when I silenarmy it stucks, so I had to add config option to use only 1 instance. Now its running fine and it makes total 67 sols. I do not know if that is good.
When I look at gpu utilisation on atitweak, O see utilization is low. why?

here is the output of atitweak:

tim@rig0:~$ .local/bin/atitweak -s

any suggestions?

/sa-solver' biinary; make sure to run 'make' to compile it.

How can i fix that?  I ran make and no file found.

I can not wait for the next version is to provide support for NVidia cards :-).
