[CLOSING DOWN] ScryptGuild Auto-Switching Pool

[BitMinerN8]

I just got 20 Gridseeds a couple days ago with a Rasp Pi.  At 850 MHz, almost no HW errors.  I'm expecting around 7.2 MH (360 kh/s x 20), but Scryptguild says I'm getting around 6.2 to 6.5 MH.  It's been hashing for 48 hours.  Lots of rejects though (anywhere between 6 to 10%).

Even so, would that account for an almost 1 MH/s discrepancy?

PS:  Also tried it at 800 Mhz.  Expected rate should be 6.8 MH/s, but I see 5.8 to 6.2 MH/s on Scryptguild.  All units are hashing away with little to no HW errors either.

What mining software?

I'm seeing around 6.7 to 7.0 MH with 20. It's strange, I have drop offs I can't explain, it looks like it's running, I see shares submitted by all attached units on the display but the ScryptGuild Dashboard says otherwise. If I start/stop cgminer the speed picks up for 9-10 hours, then I see it dip on the graph and cycle again. Time for a cron job I guess. Or I was thinking about breaking them up over a couple to see if I can narrow down the bad "seed".

[Sir Alan]

Lots of rejects though (anywhere between 6 to 10%).

The high number of rejects may be due to the intensity setting; try reducing it to -I 13 which is likely to reduce the number of rejects, although you probably don't want to get it down to zero.

Remember that the hash rate shown on the ScryptGuild site is an estimate - a back-calculation based on submitted shares - rather than a definitive count, although it shouldn't be far out.

I have found that Cgminer (3.7.2) can benefit from the occasional restart: it tends to fall over after running continuously for a week or so.  I would too.

I see the same.  I set minimum difficulty at 256 and before it auto adjusts to 512, rejections were lower.  I get about 6.8 to 7 MH for the first few hours then it drops as low as 6.2 MH.

As for intensity, I don't think there is an intensity setting for Grid seeds.  And the Scryptguild has rate estimation explanation doesn't account for a full MH missing.  I have GPU hash rates that are closer to the reported hashrate on cgminer.



I'd like to know how to create a schedule to reboot or restart cgminer.

[Sir Alan]

I'd like to know how to create a schedule to reboot or restart cgminer.

You could try CGwatcher.  That will monitor it, restart it at specified intervals if required, restart it if it misbehaves, etc.

I find the hash rate varies throughout the day, presumably something to do with the bandwidth available in the area.  Mine goes from a high of around 220K, falls to around 190K during late afternoon and evening, then climbs back up again.  That's on what is supposedly a high speed fibre optic connection; if I switch everything over to an ADSL line (I have both available) it drops by at least a quarter at any time of day.  BTC mining on Slush's pool using BFGminer varies in the same way.

If you aren't using your gridseeds in dual mode, use BFGminer - no HW errors and averaging about 355k/hs per device at 850. http://cryptomining-blog.com/1883-download-the-latest-bfgminer-3-99-0-for-windows-with-gridseed-asic-support/

I'll look into it.  Cgminer is reporting 360kh each (total 7.2 MH) as well. So did BFGminer on Windows.   Its the pool that says different.  I know the pool is an estimate but not by THAT huge a difference.

If this is bfginer for Rasp Pi, I'll check it out.

Is it possible to merge mine scrypt coins, rather than just one at a time?

If you're using Windows, this can be done really easily with some batch files and Task Scheduler.

Where I can find the non-automatic conversion now? I found Automatic Conversion on/off button only.

If you want to turn off automatic conversion for a certain coin, set an extremely high reserve for it and set your wallet to a local wallet or an exchange.  Manual conversion was only available as a means to test a high volume of trades on Cryptsy to identify all of their (MANY) API failure/errors/inconsistencies before automating the process.

Thank you, I thought you plan to keep and manual and automatic conversion on your site.

Yeah, I'm pretty familiar with Windows.  I'm a fish out of water with the Rasp Pi.  I did find a way to do it using cron.  It doesn't help though.  Seem like 6.2 to 6.6 MH/s is the best I can do with 20 GSDs at 850 MHz.

Be careful there are a lot of cgminer 3.7.2 versions out there. They are not all equal. I had a early version that did not detect a USB issue and the unit appeared to be mining but is you looked closely the accepted shares for one tor two units would stop increasing. switch to a new version that displays the serial numbers and allows individual clock setting and this version would show a unit dropping off due to a USB error. I wrote a script to monitor cgminer via the API and stop and restart cgminer if a unit stops working. you need to have --api-allow and --api-listen w:127.0.0.1 command line settings.

Here is a copy of the script. Don't judge my programming skills by this script it was a quick hack. I called the script "check_cgminer". It assumes you have a startup script called "start.sh" in the directory "/home/pi". The crontab entry I use is "*/5 *   * * *   root    /home/pi/check_cgminer". This checks the that all the gridseeds are healthy every 5 minutes.

if you run the script with the -v option it outputs diagnostic data. "./check_cgminer -v"

Good luck.

Hey eleuthria,
How about adding Einsteinium (EMC2) & Potcoin (POT). They seem to be pretty profitable these days.

Also, how about stats like btc/mhash daily etc...
I know numerous people have asked for this in this thread, but you somehow don't want to do it.

I know it is your pool & you can do what you want, but believe we would have more new people coming in if they had the Stats to see.

I have been here since this pool started & have zero complaints, but it would be nice if we could grow more that the 3Ghash we've been stuck at foe weeks.
I believe the STATS would help attract more people as mining is all about statistical data.
Just me 2 Cents.
Bye.

[w5pn73]

Just a note: the recent conversion list on the convert to btc page is getting huge... can you add a page switch or a filter to display only the last n conversions ?

Thanks.

Hey Eleuthria.
Could you please add a new value for 'Rejected shares percentage' for every worker to 'Rejected shares' column or just a new column in 'Dashboard' section as on screenshot?
This information is helpfull to watch for workers and investigate high stales rate.
Also I would like to see 'Total Rejected Shares percentage' in the bottom of that column.
Thanks.
