Hi Merc82,

Did this payout happen?

2014-06-02 at 11:04pm EST: Mandatory Payout #3 will go out tomorrow, June 3 -- Any account with > 0.002BTC, and not paid in 5 or more days. Thanks!

Because I have a small balance that I think should have been sent, but it didn't.

If the payout event did happen, then let me know and I'll PM you my account name.

Thanks in advance.

Hi suchmoon,

Earlier on this thread you dropped the ghash.io multi pool due to a combination of poor profitability and technical difficulties with the pool. Do you think that it's worth trying them out again?

It would be nice to have some more scrypt choices for us poor schlubs that are stuck with ASICs.

Never mind. I think the whale just showed up on CM.

Big drop in Scrypt hash rate. So where did the whale go this time? Not to CM apparently because its hash hasn't gone up.

Yeah, in retrospect I guess there's no way for a pool of multi pools to effectively use short term statistics to make reasonable returns. Multipools are all about averages anyway. The best they could do would kind of be an "index fund" of script multi pools.

For grins I looked at their stats and the average over the past 10 days was 0.00251. You'd get the same result by just sticking with CM for the same period.

I guess people will try anything as scrypt mining nose dives into 0.001 territory...

Is it worth adding magicpool.org? Apparently it's a pool of pools, auto-selecting between multi pools.

I'm skeptical that another level of indirection (and more fees) can make much of a difference, especially since there often doesn't seem to be that big a delta between the multipools. But it might be interesting.

I don't know where else to post this, but wafflepoolmonitor is displaying an error at the top of the page:


Maybe the recent changes for script-n are providing new or different JSON values to the API that wafflepoolmonitor doesn't handle yet?

Note that this just seems to be cosmetic. Wafflepoolmonitor seems to largely work, even with the recent changes.

The Minera/cpuminer combo is really amazing. I moved my main rig to it this weekend. Excellent work!

One thing I noticed is that if you have logging on and you stop and start the miner, the log file gets overwritten. I had logging on in debug mode with auto tune on so that I could tell when auto tune was done. Once I harvested out the per chip frequencies and added the command line, I disabled debugging and restarted the miner. It zapped my existing log, which was a bit disappointing.

Maybe this is a cpuminer issue and not Minera? I guess what I'm asking for is that cpuminer append to the specified log file instead of replacing it. If this is a cpuminer issue, then I can post on the corresponding support thread.

Also, it looks like log rotation is enabled with Minera, but I have yet to see the cpuminer.log get compressed and rotated. I think it's been 24 hours since I set up the rig, so I would have expected the log to rotate by now.

My only concern is that I'm using ramlog to minimize thrashing the flash card and as a result I have a relatively small (50 meg) mount point for /var/log. I find mining logs very useful, but don't want to exceed the space that I have.

Note that I installed Minera from the instructions to my existing Pi. I'm not using the Minera Pi image, in case it's relevant. Maybe something is missing in the manual install instructions for log rotation?

Thanks in advance for suggestions.

It would be nice if the Recent Payouts list indicated which pool they came from.

I got a little confused this morning because I got a payout that looked smaller than expected. Turns out that that payout was from the nscrypt pool, and was preceded by the expected larger payment from the scrypt pool.

Web site access is still spotty this morning, but it looks like maybe you're bringing nscrypt out of beta and changing the site accordingly.

I'm having trouble accessing the web site this morning. Sometimes it works and sometimes it hangs with a CloudFlare error. Even when it works, I can't seem to access the nscript stats, either globally for the site or for my miners.

Mining seems to be working though, according to my rigs. At least they are submitting shares.

Hi michelem. Just checking in to see how the start/stop daemon is coming. Are you still going to add that?

The "whale" moved to CM, I think.

I've got to say, wow! I like the new stats page! Graphs! It's like a statistician's wet dream ;-)

At first I was concerned because my ScriptN rigs are so underpowered, they looked like a smear of grape jelly on the floor of the graph view. But when I unchecked my much more powerful Script rigs, the graphs nicely and automatically zoomed to give me good detail. It even exposed the fact that one of my ScriptN rigs had a slump in performance that I didn't otherwise know about.

I guess my feedback would be that the stats page is really busy. But I don't know what you'd do about that and still provide this level of detail. Maybe if there were options to hide/disclose sections of the stats.

Also, when I refresh the page it forgets the checkboxes selected in the "show" column. That can be a nice if you want to show all active rigs, or a not as nice when you want to keep the graph settings that you selected. Maybe if the session could remember the selection, with a toggle to show all active rigs?

Maybe it would be nice to be able to sort the workers grid (by column heading)? I've got 9 workers across 2 pools now, so it would be cool to be able to sort by algorithm, for example.

Anyway, these are just nits. You've really done a nice job here. Thanks for all the hard work.

OK. Thanks for looking into this.

In case it helps, I'll PM you my BTC address.

It looks like unconverted coins are piling up. Is this just a stats display problem? Maybe I'm seeing it because I'm on the Scrypt-N beta?

I guess I'm number 7 now ;-)

Yeah, what suchmoon said. Thanks for this. It's very cool.

Poolwaffle, where should we provide beta feedback? Should it be here in the public forum, or would you prefer PMs?

Never mind. I just tried it and the answer of course is yes. I can see my worker name under the "nscrypt" stats.

I still don't know what difficulty to use for such a small amount of hash, so I'm using 8 for now.

A couple of quick questions regarding the Scrypt-N beta.

Can we append worker names to the end of our BTC address, like we can with the scrypt pool? Sorry, but this wasn't clear from the beta notes.

I have only have a pathetic amount of hash to point at the beta currently. I've got around 40 KH/s now, and can bring that up to around 90 KH/s later tonight. What difficulty should I use? Looks like 8 is the lowest.

Has anyone built this for Mac OS X yet?

Does cpuminer track when the pool changes difficulty? I'm mining on waffle pool, which now has the option to set the difficultly in the password. Previously the difficulty was always set to 512.

Since my test rig running cpuminer is only about a 1 MH/s, I tried reducing the difficulty to 256. What's supposed to happen is that the difficulty is set by the pool to 512 at first, then reset to the desired value with the first block change.

But what I'm seeing with cpuminer is that it always thinks the difficulty is 512, even after a block change. Here's the relevant info lifted from the screen output a few minutes after starting (and definitely after a block change):


- and -


Note that I'm sure that the Wafflepool feature works because I've made the same change on my Dual Miner rig, which uses gcminer. I can see in the log that it starts out with a difficulty of 512, the within a minute changes to 256.

So maybe cpuminer gets the difficulty up front and never changes it when the pool indicates that it's changed. I guess that this is just a cosmetic issue, since the difficulty stated by the pool doesn't impact hashing on the client. But it would be nice if cpuminer reported the current difficulty accurately.
