This will be a strange question but is there a recommendation for a getwork-stratum proxy that currently works for BLC? I am still working on my oddball collection of FPGA and I just salvaged another one from a junked Flywheel UPS control board a few days ago. I was able to modify Kramble's FPGA blakeminer but it still setup for getwork and I need a proxy to test with.

Long term, I need to add support for stratum but I am still testing and it is easier to test one thing at a time and a working stratum proxy would help. I have tried using slush's but it has seriously bitrot and I am fighting Python dep problems.

Thanks

I am interested in adding to my collection of small miners and I am looking to see if someone has a old DU-1 that they are willing to sell for a reasonable price.

I tried to send you a PM but will you accept $100 + shipping to Zip 25560 for your mini? I was looking for a PinIdea DU-1 to add to my collection but a Baikal mini would work as well.

Thank you for your consideration.

As I discovered with my 7-port, 60W charging hub from Plugable -- pop it open and look at how the power is distributed.

On the Plugable, it takes 12vdc in and has 3 buck regulators taking that down to 5v for the USB plugs. That said... 1 regulator feeds ports 1 & 2, the 2nd regulator feeds ports 3 & 4, the 3rd feeds ports 5-7. See where this is going?

Given that you can only use 3 ports, do you still need 60W or is the 25W unit acceptable. I would be using the Pluggable 7 port hub to run a couple 2PAC sticks and I can order 2 Pluggable 25W units for the price of the 60W unit.

I realize that this is a old post but I have a need for a AMD CAL capable miner right now. I am working on some interesting blockchain ideas and I needed several nodes to play with. At work, a number of AMD CAL (RV630) cards were being discarded and I was able to pick them up. Mesa/Gallium OpenCL support has not reached these cards yet and official AMD drivers do not support OpenCL for these cards. They are CAL capable and I have tracked down only 2 miners that supported CAL, hdminer and ufasoft. Hdminer doesn't support these cards only HD5000 and above.

I was able to download ufasoft_coin-0.110.tar.xz from ufasoft.com but I am having some difficulty in compiling it for Linux. I believe that I have most of the dependency issues worked out but the configure script output still doesn't show cal.h present even when I have specified the CPPFLAGS that point to the directory with the cal.h file.

Does anyone have any old instructions on how to compile ufasoft miner to support AMD CAL under Linux? Failing that, can anyone remember another AMD CAL miner that I might be able to use?

Thanks for any help!

Happy New Year Everyone Grin

Happy New Year as well! May all of you hopes come true in 2018 or at least closer!

well cgminer is a good ref for stratum but with opengl hmm maybe not

Chiguireitor(UMO dev) did do some work on a webgl miner some time back and tbh that would be best place to start but I dont think he released the source (probably due to beta/alpha code) might be an idea to drop him a line here or via his twitter @johnvillarz and see if he can help point you in right direction before you go too deep Cheesy

on side note next year might start to see asic's for blake256r8 so not sure too much work on GPU/FPGA is best time spent unless its for learning or fun Cool

I will address the second point first. I have heard rumors but I haven't seen anything that is solid yet. If you have better information then please share it if you can. I was under the impression that the blake256r8 ecosystem was not capitalized enough to justify the tapeout costs of an ASIC. I have been mining on eu3 and I never see more then 20 miners at a time. If an ASIC is made then I will be very disappointed since I really don't want/can't get involved in a arms race. Until the dark day arrives, then I am trying to spend up GPU and FPGA

Your first point is useful to me and thanks. WebGL is a JavaScript binding and probably not what I am looking for but it is interesting nonetheless. This is the post that I was referring to. http://bitcointalk.org/index.php?topic=4618.40

This is going to be strange question but it related to blakecoin. If you were going to start today and attempt to incorporate a previously unsupported compute processor into mining blake; what would be the mining software that you would start with as a base? cpuminer, cgminer, poclbm, bfgminer, something else? If the answer is start from clean paper design, is there good modules for UI and stratum/getwork that can be used?

At work, I stumbled into a cache of e-waste medical imaging cards and some of them are AMD based on the R600 series GPU. At the present time, the R600 series is not supported by any official AMD driver for OpenCL since they were CAL cards. Mesa and the Gallium tracker doesn't have support for these chips, just some of the later HD4000 series cards. I have looked for a CAL miner that I might hack in blake256r8 support but some of those were private back in the day and I can't find source. I saw in a couple of posting here in bitcointalk that I need to find again about some experiments to use OpenGL Shader Language which both the Mesa 3d drivers and last official AMD driver supports. The post included sample SHA256D code which gives me some good refernce to start from. BD had posted sometime back optimized modules in different languages for using blake so that is sometime to look at as well.

Why use old and obsolete GPU when a better card is available anywhere? These cards on paper have more shaders then many of the Nvidia cards that I have so for a practical reason it might be worth exploring. I like learning and the idea that a GLSI is technically mire cross-platform than OpenCL is technically interesting to me. It is certainly not going to make me wealthy but that was never the point. Using discarded equipment and learning about blockchains and cryptocurrency WAS the point.

Sorry if sounded a little preachy there..some other coworkers with Antminers have no idea why I work with unusual equipment.

Hi expert
I am using NVIDIA GTX 1070 x 5 units

i try ccminerv2.2 and ccminer-x64-2.2.2-cuda7.5

both end up with error salsa_kernel.cu:550

can anyone help me on this?

Thanks

I don't really know since I am not running ccminer but you might need to compile from source if you haven't already done so since CC 6.1 which is what your cards support is pretty new for ccminer. You might have to adjust the Makefile after the configure.sh script to include CC 6.1 support.

If you have already done so then where is this error showing up at?

Code:

r-util.Tpo -c -o ccminer-util.o `test -f 'util.cpp' || echo './'`util.cpp
ccminer.cpp:49:26: fatal error: cuda_runtime.h: No such file or directory

Got this error when try to build.sh. Already do autogen.sh and configure.

Hope someone can help me to fix this error. Thank you

I don't use ccminer since I do not have cards that are CC 3.x or above but it looks like from your error message that you might not have the Cuda Toolkit installed?

If it is installed and you selected the samples then there is a Utilities directory under the location that you installed the samples. It is typically under the /home/user that installed Cuda. In the Utilities directory is a deviceQuery and after that is built then you can see that Cuda is running correctly. It is also possible that the location for the Cuda libraries is not in the PATH.

Hope that is helpful for a place to start.

Hey, Creativereef17 you seem quite informed on this topic specially when it comes to mining with laptops, I wanted to make use of my Gpu maybe overclock it, but I was less concerned about what to mine, I was thinking about selling my power to nicehash pool and in return I could get some satoshis, I can run it full time 24/7 but nicehash miner and minergate and ccminer are all using my cpu, maybe I will mine blakecoin but I don't know about open cl yet, can you just point me to right direction how you get your gpu to mine, I think this NVS 3100m gpu is pain in the a**, thanks for reply anyways, you made my day,

hope you'll reply again soon,

The first question is what OS is on the laptop? If it is Windows then it is a little bit more complicated since I don't think that any of the binaries are still available for cudaminer which means that you will have to compile the source code from github. I believe that cbuchner1 was using Visual Studio 2010 when cudaminer was being developed. There is a article at http://cryptomining-blog.com/tag/compile-cudaminer-for-windows that may be of use.

If the laptop is using Linux than you might use this link. https://github.com/cbuchner1/CudaMiner/wiki/Howto-Compile-cudaminer

I don't think that nicehash works on Cuda, just OpenCL so you will need to play with it to get it to work. Using old equipment for mining means that you will have to learn and test many combinations until it works.

For the record, I don't have it all worked out either, AMD is clearly easier to work with but if you have a stack of Nvidia cards like I do then you try to make them work the best way that you can.

Good luck

Hi everyone, can someone help me, I have Dell Latitude E6410 and it has Gpu Nvidia Quadro nvs 3100m compute 1.2 I think. I want to know should I download ccminer and cudaminer both or just one especially I need help with creating .bat file for me additionally What else I need to download, Thanks in advance I'm a newbie in mining and on Bitcointalk.

First, welcome to cryptocurrency! It is a long and wild ride ahead of you to learn what you would and maybe make a little profit.

I have mined with a E6410 in the past and there are questions that will need answers.

1) What coins are you thinking of mining? Some coins are not suited to is equipment and some might be.
2) What operating system are you running or plan to run on this laptop?
3) Do you plan to mine full-time on this laptop or use for work/school/whatever

I found that getting a cheap laptop cooler to place under the unit helped with temperature. Close-out stores sometimes have them cheap.

That GPU is not compatible with the later ccminer. ccminer requires a GPU with a later Compute Capacity then your card.

You have two choices with mining software. If you wish to stick to Cuda architecture then cudaminer is the only option available to you. If you wish to use OpenCL then cgminer and ports up to 3.7.2 support GPU runing OpenCL. This issue is that Nvidia doesn't really optimize OpenCL drivers in their equipment and OpenCL 1.1 which is what your card supports is not very quick.

If this is an interest and a hobby to play with than have fun and maybe learn something. If you are looking for profit, probably not going to do that with this equipment.

I certainly do not want to bias you in any way but if you are unsure what coin to mine then with that equipment then you might look at Blakecoin using the Blake256r8 hash algorithm. I think that it makes sense for lots of reasons but you Google it and make up your own mind.

@CreativeReef17
Honestly unless you have free electricity its probably not going to be cost effective to mine blakecoin on old nvidia cards. Most people are probably using FPGA or Nvidia Pascal. But if you still want to give it a try, the miner version i ended up using is ccminer from here:
https://github.com/cbuchner1/ccminer

Thanks, I had thought from your original posting that you were using the original cudaminer and not the later ccminer. My older cards of which have several are lower CC than what ccminer supports and it sounds like that you were using the cudaminer complied for your board.

I was using them for scrypt when I was running my rig but something has changed since they are not rolling over now. I ahve reverted all changed back to what I believed was stable code both OS, nvidia drivers and cudaminer but so far no joy.

Thanks for your help.

It is a belated but I didn't see any posting on the 4th anniversary of Blakecoin. If remember correctly, it is October 6th, but BD will have to state the Official Blakecoin Day. Traditionally, 4th Anniversaries are celebrated with fruit and flowers so hopefully BD gets some this month

Here's to many more! Long Live Blakecoin!

Welcome to this little slice of what is an ever expanding crazy crypto universe Cheesy

If you need help with flashing Lancelot, Icarus or Cairnsmore1 FPGA's, I have a step by step here-> https://blakecrypto.com/forums/forum/user-manuals-guides/

Thanks, I don't have any FPGA miners since they never show up for sale with the exception of a Cairnsmore seller on ebay that is parting out a large rig but those are pricey. It might be a decent price if as a FPGA development board since it has 4 LX150 but it is not cheap. What I have are FPGA that were in consumer items. I have 2x Cyclone IV, a Spartan 3 and a Spartan 6 that are part of various items.

RL is keeping me busy right now but I am trying to rebuil parts of my old mining rig and getting the FPGA out of storage. When I am closer to working on them then I plan on posting about them and possibly getting some help from kramble and others to get my bitstreams cleand working on blakecoin.

Hey BD, I'm trying to set up mining with a gtx 1060 but am having some issues. Managed to compile the cuda miner in your repo after editing the make file to have -arch=compute_61, but am getting frequent timeouts on LA1 pool. Also cudaminer is showing I'm getting only 20MH which seems slow. I compiled against cuda 8.0. Is there a better cuda miner to use, or maybe its using the wrong Blake algo ie 14 round? Would love if you could release an updated cuda miner that properly supports Pascal, but know you are already busy. No idea why my ping to la1 server is around 30000ms though. Any help would be greatly appreciated.

I have several older Nvidia cards that I working on spinning back up for mining blakecoin. You probably already are aware of this but there are significant differences between cudaminer and the ccminer branches. if you have a newer card than one of the ccminer branches would be better performance.

AFAIK, the cudaminer by Christian Buchner was the first miner that utilized Nvidia Cuda architecture instead of OpenCL and it supported Nvidia Compute Capacity (CC) from 1.x up 5.x depending on which Cuda Toolkit is being used. Cuda Toolkit 6.5 is the last version that supports CC 1.x. It was intended to mine scrypt and a few other algorithms that theoretically Nvidia microarchitecture has a advantage in mining over ATI/AMD. Toward the end of development of cudaminer, Christain added blake256 (8 round) support into the codebase but mentioned that it was not optimized.

ccminer was started by Christian and others to further improve on Nvidia performance but in so doing remove older CC kernels that was being decraped by Nvidia anyway. ccminer needs at least a CC 3.0 to run and probably at this point maybe a CC 5.0 to compile.

I don't have any high CC cards so I am stuck with cudaminer but that is not a problem. I have a small stack of AMD cards and 4 FPGA that I want to play with again so I have so toys for the winter.

BTW, what OS and driver versions are you running on your cudaminer rig?

Thanks for your time.

It has been kinda of quiet here recently and it seemed like a good time to make a few posts. I am coming back into cryptocurrency after a absence with a new handle and no baggage. The last time around was unpleasant and I wish that I had found a community like this one the first time around.

I have spent some time reading all 190 pages of this thread to get a feel for the culture and mores of this group and I really like what I see so I hope to contribute some more in coming weeks. Like most of us, RL and work involve with our hobbies but I hope to be able to spin up parts of my old mining rig and point them to BlueDragon's pools.

Thanks for being welcoming to a long-term lurker

Thanks for all of the assistance! I had added a couple of nodes but it wasn't finding the blockchain. I will try again and if I need to then I will download the chain snapshots

I just downloaded the Windows Qt wallet and I can't seem to find a block source. What nodes are currently active right now?

Thanks for your assistance
