[Dev] NeoScrypt GPU Miner - Public Beta Test

[A Former User]

Howto

Getting started with gpuminer

• Linux: Get the program
  • download latest version from github here.
  • extract the zip file into an empty directory.
• Linux: Compile the program (Detailed build FAQ coming soon)
  • change into that directory anr run ‘autogen.sh’
  • correct any errors that may be show. Typically some build tools may be missing.
  • run ‘make’ and optional ‘make install’ as root.
• Run cgminer
  • run “cgminer --neoscrypt -o http://: -O :” *without the “quotes”

1. Windows: Get the program

• either follow the steps for Linux and use mingw to compile the program or download the precompiled .exe file from any of these links:
  http://www.ftc-c.com/pack/testnet.rar v3.7.1
  https://www.dropbox.com/s/mbteys6opg4odlj/cgminer-3.7.7.bNeoscrypt.zip?dl=0 v3.7.7 *updated*
  https://forum.feathercoin.com/index.php?/topic/8194-download-the-latest-neogpuminer-378-here/ v3.7.8

2. run cgminer

• run “cgminer --neoscrypt -o http://: -O :” *without the “quotes”

FAQ

• Q: What is the best way to start mining Neoscrypt?
  A: Start with a minimal configuration file or no configuration file and use the autotuning feature of cgminer to determine the best settings.
  A sample config file is attached to this post. Adjust the pool names/usernames to your needs.

• Q: Is it possible to use a backup pool in case the pool I use is down?
  A: Yes, is is possible to specify the -o and -O option several times to use another pool, if the first one specified is not reachable. The attached config file also shows how to archive a redundant pool connection.

• Q: Do I need to specify environment variables to run cgminer?
  A: No, setting of environment varariables, e.g GPU_USE_SYNC_OBJECTS and GPU_MAX_ALLOC_PERCENT did not show any increase in hashrate during the initial tests

• Q: Can I use cgminer for CPU mining?
  A: Yes, specifiy the ‘–opencl-all-devices’ command line parameter

• **Q: I get an Error message when starting cgminer: **

  Error in configuration file, partially loaded.

**A: **This is a known bug while parsing the config file. Cgminer will work without problems. The error will be fixed in one of the next releases of cgminer
*
Q: I get the following error when starting cgminer:

Unable to open neoscrypt140909.cl or ./neoscrypt140909.c
l for reading
 [2014-09-30 18:05:12] Failed to init GPU thread 0, disabling device 0
 [2014-09-30 18:05:12] Restarting the GPU from the menu will not fix this.
 [2014-09-30 18:05:12] Try restarting cgminer.

A: copy the file neoscrypt140909.cl from directory you used to compile cgminer into the directory you use to start cgminer

I had pulled a gpuminer , it is cgminer 3.7.1 . You can download it from http://www.ftc-c.com/pack/testnet.rar

[ghostlander]

It doesn’t work currently for HD5000 and HD6000 series cards. All HW errors.

For some reason there are some random extra characters at the end of the link above

[vehre]

For the HD5000 and HD6000: can you send the output of “clinfo” for these card? I am most interested in the extensions section. There needs to be the extension cl_khr_byte_addressable_store available or we stand no chance to get the cl-kernel running on this cards.

[ghostlander]

Here it is for one of my oldest mining rigs. Two HD6750 (the same to HD5750) + one HD5870. Catalyst 11.12 + APP SDK v2.6. The drivers cannot be updated any further because AMD have disregarded the OpenCL support for Windows XP and 2003 since spring of 2012. These cards deliver 2x 200KH/s + 380KH/s in Scrypt using the standard (ckolivas) kernel. If we make it running there, the other cards and platforms will be also compatible most likely. The general idea is to make the kernel compatible with the largest possible selection of computer hardware.

timuir, the connection varies between 0 and 12 kbs can you please upload elsewhere… :)

[daimyo]

alright, got it finally but no ping from the pool.ftc-c.com

lets try it for pxc

update:

Working fine with morehash.pw NOMP pool. Pulling out the same hashrate 8.35khs out of GT 550M only now not getting the graphics driver unresponsive upon shutting down the miner.

How to get “clinfo” for these card ?

I think AMD 7800 series cards still have a issue with AMD 13.12 Catalyst + SDK 2.9. They are very low hashrate.

[tmuir12]

alright, got it finally but no ping from the pool.ftc-c.com

lets try it for pxc

update:

Working fine with morehash.pw NOMP pool. Pulling out the same hashrate 8.35khs out of GT 550M only now not getting the graphics driver unresponsive upon shutting down the miner.

Yes, pretty sure it wont work for FTC yet as its for Neoscrypt and we haven’t swapped over yet, but does work for PXC

How to get [background=#ffffff] “clinfo” for these card ?[/background]

Type “clinfo > somefile.txt” in your console.

This is my AMD card clinfo. AMD HD6850 ,HD6870,HD6770 and AMD HD7850, HD7950 in attach files.

Folks, does that mean that in order for the gpu miner to work best, you first need to have it optimized for every particular video card?

[vehre]

Of course not. I do have an Nvidia card only. I need access to an AMD one to do some tests and figure what the issue here is.

Great. I hope this time the nVidia graphics are gonna have the advantage :)

[Bushstar]

People’s experience of NeoScrypt is going to be based on the GPU miner. We could not launch without a GPU miner as the trolls would have a field day and who ever did come up with a GPU miner might not have released it, however we could not launch with a buggy miner either as people’s experience would be too poor.

Then again it is said if you wait until the software is perfect then you have waited too long. Considering this I suggest we set the fork date, Ruth said she spotted a rough date given by someone and I intend to aim for that date after conferring with a few others. I expect to have forked to NeoScrypt by the end of October.

There is a Feathercoin testnet running NeoScrypt but this was to check that the fork works as expected, to test NeoScrypt it is best to mine on Phoenixcoin and earn some real coins while you are at it. As the Feathercoin testnet successfully forked to NeoScrypt on the testnet we have confirmed that the code is complete and we have seen Phoenixcoin successfully fork to it as well. We know it is safe to move the network to NeoScrypt and have auto checkpointing in place to prevent any abuse of low hash power during the change over. I would not like to fork from one algo to another without some sort of protection, especially considering how much we have been bullied over the last year and five months.

Feathercoin is committed to longevity and to explorer new solutions outside of the status quo that Bitcoin has to operate within, this is why we exist.

We really have been waiting on NeoScrypt for such a long time and I look forward to a fresh burst of energy once we can get on to the other side of this technical change. After we move we should cherry pick ideas and discuss them to pick the bad from the good.

Sorry daimyo,

not any longer. I just aquired a Sapphire HD6870. Just have to wait for delivery. For figuring what is wrong in the CL-kernel that one should be sufficient.

For the nvidia vs. ATI battle: I do not favour any of the two. Both are evil, not participating on the Linux kernel. But to get OpenCL enabled Intel-HW my funds are too limited. A Xeon Phi would be marvelous, if anyone wants to donate :)
