1  Alternate cryptocurrencies / Mining (Altcoins) / Re: HashPeak - GPU mining hashrate peak detector on: May 13, 2014, 07:07:51 AM
I don't know if the CGBenchmark and CGTuner work for x11 and scrypt-n or any other algos but I know haskpeak does and I like it. Are there any future plans for you to implement some of the other features they have?
It's coming. I started working on adding gpu mem clock support last night, but I only got an hour or so though before I had to turn in. The features are not difficult to implement. The only real issue is the graph. If we have 50 different memory clocks and or intensity/xintensity settings, the graph will be very cluttered.

You mentioned temperature readouts. I'm not sure these are all that interesting considering we only run each set of clocks long enough for the hash rate to stabilize and it's unlikely that the temperature will reach its maximum during that short period of time.

Hmm. Had I known these existed, I probably wouldn't have bothered with writing HashPeak. However, it appears all three applications have their individual pros and cons. Now it's just up to me to make sure that HashPeak has only pros :-) That is, when the kids will let me spend a few hours by myself.

Have you considered automated varying memory clock too?  (effectively making this three dimensional -- a stack of graphs like you made)  I ask because I've read hints that suggest that there exist lower 'sweet spots' of gpu/mem clock that exert similar, or slightly lower hash rate at a much lower power draw.
Yes, this is on my todo list. I just need to find the time to add it. I'm thinking it might be prudent to try to estimate the amount of time it will take to iterate over all permutations of mem and core clock and warn the user if it is likely to take a very long time.

Any suggestions on how to plot the graph in that case? If the number of mem clocks is large, the graph will be difficult to read.

Can you provide some syntax on how to do the --host command?  Not sure how to do the api and port part.
README.md has an example using the --host and --port commands. If you're running this locally though, you probably don't need to specify a host and port. My guess is that you haven't enabled the API in your miner properly. The readme has details on this as well under "API access".

Does this need to run from inside the sgminer folder?
Nope. It communicates with the miner via IP.

Does it work with sph-sgminer?
I don't know. I have never tried sph-sgminer. I can't imagine there are any changes in the API though, so I think it should. Perhaps you can try and get back with the results?

How do you use it with an X11 coin?
Another thing I haven't tried. I think it should just be a matter of running it against the miner. It doesn't really care what algorithm the miner is running as long as it reports back the hashrate.

Just putting it on my c: drive and using a .bat file with your sample config and it just crashes.  Using sph-sgminer.
Try running it from a command prompt so you get to see any error message that might appear.

upgrading from sgminer 4.1.0 to 4.1.271 fixed the problem.
Thank you very much for being helpful in tracking down the issue (via PM). HashPeak should work with 4.1.0 anyway, so I've released an updated release that addresses the API issue you were having.

Cheers,

I'm working with pomelo to sort out the problem he's having. For some reason, the JSON returned from his sgminer API doesn't match what my local sgminer returns. The issue should be resolved soon.

This is amazing!

Are you planning to add more settings to it? (Intensity, xIntensity, threads, etc.)
Adding more settings wouldn't be difficult, but it depends on whether you would want to test those settings individually or together with GPU clock. Individually is doable, but if you want to test multiple settings in the same "batch", the amount of time the application will need to complete the test will multiply with each setting. I think, before we add any new settings to test, we need to figure out which ones make the most sense in order to relatively quickly find the hashrate sweetspot.

able to port it to linux? this looks amazing! If you aren't able to port it, hopefully someone can join your github team/fork and make a linux port! Cheesy
It should run on linux right now provided that you have mono installed. If not, I'm pretty sure I can fix it. Making it run without Mono means rewriting the application in some other programming language and that's not something I have time for at the moment.
7  Alternate cryptocurrencies / Mining (Altcoins) / Re: HashPeak - GPU mining hashrate peak detector on: May 05, 2014, 03:18:52 PM
the program just crashes on my win7 + sapphire HD7950 with 13.12 Catalyst + sgminer 4.1.0

That's odd. Did you run it by just clicking the exe or did you run it from the command prompt? You need to do the latter. Do you get an error message?

PS. What video card or drivers you run are not relevant since HashPeak only communicates with the miner through the API.

Cheers,

HashPeak

What's this?
Determining the most effecient hashrate for GPU-based cryptocurrency mining is a tedious process. It usually involves manually trying a large number of GPU engine core frequencies and keeping track of the resulting hashrate to detect any peaks in hashrate. HashPeak automates this process.

HashPeak is a .NET 2.0 console application that connects to a running instance of sgminer or cgminer, sets a GPU engine clock, waits for the hashrate to stabilize and then measures the hashrate. The application is provided with a range of GPU clocks to test and then runs through them in succession. Upon completion, the application presents the user with the lowest GPU enging clock frequency that resulted in the highest possible hashrate.

In addition, HashPeak generates a CSV (Comma-Separated Values) file including all measured data as well as a plotted graph in the form of a PNG file.

License
HashPeak is open source software released under the MIT License. The source code for HashPeak is available via GitHub at https://github.com/rickardandersson/HashPeak.

Command line arguments
Code:
Options:
    --host=VALUE           IP or hostname for miner API. Default: 127.0.0.1.
    --port=VALUE           Port number for miner API. Default: 4028.
    --gpu-id=VALUE         GPU ID to work on. [required]
    --min-gpu-clock=VALUE  Lower limit of GPU engine clock frequency range to
                             test. [required]
    --max-gpu-clock=VALUE  Upper limit of GPU engine clock frequency range to
                             test. [required]
    --step=VALUE           Number of MHz to increase GPU engine clock per
                             iteration. Default 1.
    --delay=VALUE          Seconds to wait between setting new clock and
                             testing the hashrate. Default: auto.
    --help                 Show this message and exit.

Here's an example running HashPeak on GPU with ID 0 on the local miner instance, measuring the hashrate for GPU clocks 950-1025 MHz with a step of 5:
Code:
HashPeak.exe --gpu-id 0 --min-gpu-clock 950 --max-gpu-clock 1025 --step 5

Please review README.md in its entirety for more detailed information on running HashPeak and information on giving the application privileged API access to your miner.

Miners
The recommended miner to use with HashPeak is sgminer. Although HashPeak works with cgminer, and most likely bfgminer as well, the precision of scrypt hashrates reported through the API is very limited in cgminer. In sgminer, the precision is down to a tenth of a kilohash/s, but in cgminer, the precision is 10 kilohashes/s.

Download
I've compiled HashPeak and made it available for download via https://github.com/rickardandersson/HashPeak/releases/download/v1.0.1/HashPeak-1.0.1.zip. If you have qualms over downloading and running binaries from people you don't know, you can download the source and build it yourself using Visual Studio.

The binary should run on all forms of Windows provided that .NET Framework 2.0 is installed. It should also run on Mono, but I have yet to try this. If you do, please post your results.

Hashbros offer transparent communication from the pool founders since they themselves were victims of frauds and hacks, so they seem to believe in open communication and as much transparency as possible. They offer lower fees, much better security, nicer web ui.
Please enlighten us how Hashbros has "much better security". Does it require a username and password?

I'm kinda pissed the personal stat websites still aren't working properly.  We are going on 24 hours now.  Why no updates from H2o?  He in Disney World or something??
I believe the person you should be bugging is coinGeek. He's providing the graphs for the pool.
11  Bitcoin / Mining software (miners) / Re: CGMINER ASIC FPGA miner monitoring RPC linux/win/osx/mips/arm/r-pi 3.10.0 on: January 10, 2014, 03:34:58 PM
Sorry if this has been addressed before, but I tried searching and came up empty. I'm trying to find out what the two hashrates for a particular GPU/ASIC/FPGA represent. The total hashrates shown at the top of the UI I understand - on the left a 5 second average and on the right the average since the app was started. For individual GPUs however, I'm confused.

One of my GPUs is currently showing 724.1K/728.7K. The value on the left is very stable and rarely changes, but the value on the right changes constantly (+-1K). It makes perfect sense to me that the value on the left is the 5s average for that particular card. However, if the value on the right is the "total" average since the card started mining, why isn't it even more stable than the value on the left?

Or have I missed anything?

Looking for some help with hardware, fellow middlecoiners.
I feel like I'm repeating myself, but please, your question has nothing to do with middlecoin. Please ask somewhere else.
13  Alternate cryptocurrencies / Pools (Altcoins) / Re: [ANN] profit switching auto-exchanging pool - middlecoin.com on: January 10, 2014, 10:47:28 AM
Any help would be much appreciated
Please, not in this topic. Ask it directly in the alt mining forum.

I posted this the other day in the middlecoin topic, but the topic moves fast, so in case you missed it, here it is:

I took the liberty of giving the pool website a quick makeover. I find myself staring at the graphs and tables on the site quite a lot these days and the current design is, well, not amazing. You can view my mockup here:

http://rickardandersson.github.io/middlecoin

For the sake of convenience, I only included part of the huge table on the front page. In addition, all report links in the table point to the same sample page. I also took the liberty of changing the colors used in the graphs by coinGeek. The colors I used are:

Immature: #ecdf9a
Unexchanged: #a6e38e
Balance: black (2 px wide)
Accepted: #7cb5ee
Rejected: #215b95
Three hour average: black

It's not the most exciting design (I'm not a designer), but I believe it is at least a bit better than what we have today.

h20 and coinGeek: If you like any or all of my changes, by all means, use them.

Well, I've never heard of this particular pool before, but they do have a contact page in the main menu of the site that takes you to this form:

Perhaps you should try that first?
20  Alternate cryptocurrencies / Mining (Altcoins) / Re: Best 7950 settings? on: January 02, 2014, 12:15:10 PM
I don't have any 7950's so I can't say what the expected hashrates are, but just read through ckolivas notes on optimizing GPU and follow his steps:

https://github.com/ckolivas/cgminer/blob/v3.7.2/SCRYPT-README

The only thing I can note about your settings is that you have a very low temperature target. I believe the safe limit as set by AMD is 95 degrees. Personally, I try to target around 80.
