[Dev] NeoScrypt GPU Miner - Public Beta Test

slowhash

Well, in previous releases the worksize multiple of 64 thing has been complete hogwash… No reason to start assuming it makes a difference now.

As the kernel gets better, it will become more true.

Anyone else get this with GPU temps? (GPU # 4) I never saw it before using wolf0’s kernel…

And topic is dead…

Since the neo-scrypt development is stalled, and waiting for wolf’s latest kernel and SGminer modifications to get compiled for windows with the proper files, it appears that this thread is as well.

I’m not too well, so can’t mess about too much. I’ve tried sgminer.exe windows compile with R9 270 again. It just stops immediately after starting up. Gone back to cgminer 3.7.7

Is that because sgminer doesn’t work with p2pool’s stratum?

–xintensity 3 -g 2 -w 256 --thread-concurrency 8192

cisahasa

noticed that sgminer will not support p2pools

but there is a easy way around that problem

point your miner to miningrigrental, set your price so high no one rents, then set up pool where your rig mines when its not rented(now any p2pool will work)

yes sad there is no support of p2p or solo with the version of sgminer/ neoscrypt as of yet. :-

Re: confirm no support for p2pool / stratum.

Cheers Wolf, save me doing anything further now, as limited. Also, as Wellenreiter and I have done a lot to make p2pool work and host base public nodes, I’ll have to stick with the old version.

Wellenreiter

I’ve tested p2pool with one of the first versions of Neoscrypt sgminer.

Situation is as follows:

Using ‘stratum+tcp://p2pool.neoscrypt.de:19327’ without additional parameter fails
Using ‘http://p2pool.neoscrypt.de:19327’ works as pool automatically switches to the long poll protocol
Using ‘stratum+tcp://p2pool.neoscrypt.de:19327’ AND ‘–no-extranonce’ works. the pool and the miner are using stratum protocol.

The reason of that behaviour is, that sgminer uses an extension to the original stratum protocol definition called ‘extranonce’ when started without the ‘–no-extranonce’ which is not supported by p2pool nodes.

I think, that the extranonce extension was created to support ASIC mining, so the miner can generate more work on it’s own.

As the Neoscrypt algorithm is currently not implemented on ASICS, there is no disadvantage to disable the extranonce feature in sgminer.

As I’m using a NVIDIA card, I can’t test with the current version of sgminer and the latest kernel.

If somebody could try and post the results here it would be great :)

just direct your miner to p2pool.neoscrypt.de:19327 and specify the --no-extranonce parameter in the start command for your sgminer

Thanks again Wellenreiter, genius work. I’ve now attached my AMD - R9 270 to Pool20, it is working with the windows download sgminer. It has doubled the Hash rate up to 95 KHash/sec.

sgminer.exe -k neoscrypt --xintensity 3 --worksize 256 -g 2 -o stratum+tcp://pool20.neoscrypt.de:19327 -u xxxxxxxxxxxxxxxx+0.00015 -p x --thread-concurrency 8192

Wellenreiter

did you put your hashrate and card paramter to spartans site? ;)

sgminer.exe -k neoscrypt --xintensity 3 --worksize 256 -g 2 -o stratum+tcp://pool20.neoscrypt.de:19327 -u xxxxxxxxxxxxxxxx+0.00015 -p x --thread-concurrency 8192

What hash rate are you seeing with that 270 and is it stock or OCed?

Thanks

Edit: I also tested the above config line with my pair of R9 270’s with my wallet address, but would not work for me.

Is that just a private pool and is why?

Wellenreiter

It’s a public pool and should work, but it is facing some problems due to some attacks at the moment.

What you can try:

replace ‘stratum+tcp//…’ with http://…’ the pool tries stratum first and if that fails switches to longpoll then.
try pool ‘http://p2pool.neoscrypt.de:19327’ a sister pool of pool20.neoscrypt.de

It seems to me that KNC is up to publishing firmware for their Titan miners. Someone is testing FTC on coinotron again.

Time to undervolt my rig in preparation to park her on Neoscrypt for a while.

tell me more what is happening?

majsta

@cisahasa I got an tip that KNC is testing other firmwares, now on FTC. I wanted to say that I think that they prepared their hardware part to support anything. It is possible that no one can say for some algo that is ASIC resistant. If you look what happened to nscrypt coins last few days you will understand what I m saying. If you look at few miners joining to coinotron and if you calculate you will see that they have at least 800 280x cards to achieve that performance and I think that it is impossible to have that much.

Very interesting information…

Are you saying it looks like there is ASICs in development for NeoScrypt?
