Changing the hashing algorithm
-
Suffered a setback . :(
I’m compiling cgminer on win32(x86) . My IDE is Visual Studio 2013 . After I add neoscrypt.cpp and neoscrypt.h to the cgminer.vcxproj, then compily it .
But I get a lot of errors:
ROTL32, Identifier not found
SCRYPT_BLOCK_SIZE ,Undeclared identifier
stack, Unknown size
-
This is because NeoScrypt is supposed to be compiled by a C compiler, not a C++ one. The work-around is in a PM.
-
Great work on the algo change. Looks like it might be worth haveing a p2pool test site, with all miner updates needed.
-
I believe it’s of very great importance that we don’t forget the nvidia cards out there, we want to be open and welcoming to all miners as fast as possible after release :)
-
most of my GPUs have blown up in the last 2 months.
-
One thing I have noticed running feathercoind and other coin daemons on a p2pool with tight memory. The 0.6 series daemon takes 190 MB compared to the 0.8 which are more like 230 MB. (can vary higher)
Both of which seems higher than they need…
That won’t be directly related to the algorythm, but the pool daemon pass round the work, so its something that might be “optimisation” In the builds.
Whilst we’re considering testing / improving performance.

I had a mail chat with one of the authors of cudaminer.
He is interested to add neoscrypt to cudaminer, but he can’t make it happen soon. -

Block index is held in memory. More blocks in main chain = more memory consumed.

I had compily cgminer 3.6.6 with MinGW . It can work with scrypt and keccak. But that work add neoscrypt is very complex and arduous . May God bless us !

Ok… so I definitely missed something: where do I find the files for the neoscrypt?

Step by Step ,
I had compily cgminer 3.6.6 with neoscrypt on MinGW. I set --enable-neoscrypt , Compile support for neoscrypt feathercoin mining.
I get cgminer-neoscrypt.o and cgminer.exe .
Next, there is still a very large number of hard work. Wish me good luck.

wow thats amazing progress well done. I can feel a tip coming on!

We have not an OpenCL kernel, there is still a very hard work.

Great job lizihi! :)

Is there someone official behind the ccminer? That’s also a viable option for nvidia and perhaps he/she/they have more time to add NS? :)
yes ccminer is the second miner for NVIDIA cards.
I have no contact there, but will check on Github, if there is a contact email. Otherwise I’l lcreate a feature request.
Question: can we provide neoscrypt code to the programmer of ccminer and cudaminer, or should it remain private for the time beeing?
-------Edit--------
The owner of the ccminer repository on Github is the same than for Cudaminer.
I think the answer ill be the same: yes, but not very soon…

Yes if they agree to keep it confidential until the official public release. On the other hand, if they say “yes, but not very soon”, they get the code after the public release anyway.
-
Sorry for the post, but are there any links to what Neo is about or are you guys trying to develop it from a bastardisation of blake or something?
What are the main benefits we can look forward too for GPU mining or not 100% on stats yet? (other than maybe lower power and asic _resistance _short term)
-
It is what Scrypt has been used to be: memory intensive, ASIC resistant, more secure. It isn’t a bastardisation of anything. The complete specification will be in the press release.

I will hold back the code until the official public release
