IMO Litecoin loses its point unless its CPU only Smiley
Clearly, yes. Now instead of being more accessible to everyone than BTC (because everyone has an okay CPU while not everyone has an okay GPU), LTC is accessible only to the few who are lucky enough to have the GPU miner working properly... Huge step backwards. The only positive effect is that it seems the BTC hashrate lowered a bit recently.

The original purpose of Litecoin is to be a CPU coin where anybody with their computer can mine litecoins. What has happened with Bitcoin is that GPU mining on bitcoin was a lot more efficient, so a lot of people starting mining bitcoins with GPUs. This pumped up the difficulty and made CPU mining unprofitable and therefore pointless. I don't want this to happen to Litecoin and I think most people agree with me on this.

Recently, there has been some rumors that mtrlt has modified his GPU miner to work with Litecoin. And he claims to have been able to create a GPU miner that outperforms CPU miner by a lot. Of course, all this could be FUD thrown at Litecoin by Solidcoin supporters. But I have talked to mtrlt about this and he seems genuine. So I'd like to get to the bottom of this.

Here's what I'd like to accomplish:
1) Figure out if GPU mining litecoins is indeed more efficient. And if so how much better is it.
2) Do we want to switch to a new hashing algorithm that is more GPU-hostile.
3) If we do want to switch, there are a ton of other questions. Can we modify scrypt params or do we need something totally different. How far away do we do the algorithm switch? How do we get miners/pools/clients ready for the switch so that there's no downtime?

Everyone, please refrain from SolidCoin bashing in this thread. And SolidCoin supporters, please refrain from posting unless you have something constructive to say. Thanks.

any further thoughts on this?
I think it would be good to be a cpu only coin again,
tho the retards have already said they will enjoy the challenge of getting it working on gpu...

I still don't know what is in the code.

Some one has to reverse engineer it to know what it has, it may be sending some information or anything to those who need.

It works on my Win 7 , 64 bit with out any problems, but in the beginning, it gave some errors, now working at  
~226kH/s on a 5870 running at 850/1200 clk.

This is my screen. I still don't know why other cant mine.
Also its very strange that most hero members who against it not saying anything about testing or working or not working.....


What's your opencl runtime/SDK version?

I'm getting this:
Code:
\|||||||||||||||||||||/
-  Reaper v13 64-bit  -
-   coded by mtrlt    -
-    DEMO VERSION     -
/|||||||||||||||||||||\

I'm now mining litecoin!

opencl/SDK  

AMD APP SDK Runtime : 2.5.793.1
AMD Display driver : 8.911.0.0000

Windows 7, 64 bit is on my pc.

May be aggression also causing problem.

The kernel build uses code that is specific for 58xx or 69xx GPUs... only people who own those may mine, it crashes or mines stales for everyone else.
I do have a 5870. It's not crashing, it just fails to connect to pool/daemon.

release the source code guys

In the meantime, nothing bad has happened.  The chain is alive and being hashed more than ever and it still has a lot of value.

Reaper crashes if I run it at default worksize of 256

It runs at worksize 128, but I get the same old "Couldn't connect to server" timeout message, no matter if I'm solo or pool mining.

I should put a 1 BTC bounty on this...

No idea. Its not connecting connecting sneakily another pool in my system.
It seems your download is affected with some virus or trojan or any other malwares.
I did download from there, though: http://solidcoin.info/reaper.html. I don't have the file I downloaded on this very computer, I'll post md5sum of the file I grabbed tomorrow, if someone wants to compare with their own hash.
If anyone wants to compare with the files they downloaded, here are my md5 hashes

I have Radeon 6950s on Win7 x64 bit, and this GPU miner doesn't actually work. It either crashes, or fails to connect.

Also, the fact that the LTC network hash rate DROPPED after the release of this "demo" suggests this is a HOAX, and not actually able to submit legit shares for mining LTC

Also, I didn't check what it tries to communicate to the pool, maybe it's just pinging and sending nothing. But there's some kind of connection attempt.

u have to put it in litecoin.conf & just run reaperdemo.exe without any arguments.
Litecoin.conf for
host mine.pool-x.eu
port 9332
user urpoolname with worker like xxx.1
pass ur password for pool
That's what I did, it didn't work (timeout). Note that the pool wasn't down as my other worker could connect to it without problem.

And this doesn't explain why the miner sneakily connects to another pool, as I detailed in post 118.
