I didn't read the KNC issues in detail. But one issue I seem to be having lately is if the 'pool difficulty' is high for my device, it seems more likely to crash(Temperature runs higher). Which requires a full power down of the device(BFL 60GH).  I'm looking forward to the set-able difficulty, so I can do some testing.

Difficulty does not affect devices at all.
Even if you could set difficulty, it is unlikely to allow setting it lower than the automatic variable difficulty (which is lower than most pools use on Eligius).

So for example, when it's finished, if I set the '--request-diff' flag to '64' for example, it will still give a automatic value? What is this flag really accomplishing?

Just a FYI, '64' diff. seems to be the safe limit for my device, when it starts using '128' the temp runs higher and then it is more likely to completely crash, requiring a cold boot.

Changing the diff does not change the operation of your device at all.  It still generates shares exactly the same way it was already doing.  The difficulty simply determines which shares actually get submitted to the pool.  If the difficulty is 64, then only shares with a difficulty over 64 are submitted.  If the diff is 128, then only generated shares that just happen to have a difficulty of 128 or higher are submitted.

Changing difficulty does not make your hardware work harder, or less hard, or change anything at all about the hardware operation - it just defines which generated shares actually get submitted to the pool by the miner software.

PS - The last time I mined on Eligius, the '--request-diff' flag was not honored by the pool.  I don't know if that is still true or not.

At this point I can't definitively say what I have noticed is true, but it really does look like that is the case. Also, this seems to be a more recent thing. This device has been mining for a few months now, and in the past I would typically only have a hard crash once every two weeks at most. In the past 4 days, it has happened 5 times.

I keep a pretty close eye on the ambient temps and they really haven't changed. I have a Arduino with a temp sensor next to the device and can log the temps. Is their a easy way to log BFGMiner output to a file?

From my understanding they are days away from getting the flag working.

EDIT:(20 minutes after last reboot)
Just had it crash again, I wonder if this thing is just thinking about giving up the ghost or what?  Here is a screenshot of what it does when it crashes.(from a month ago, but it's the same thing)

This issue may have been gone over already, but as this is currently at like a billion pages, I'm hoping someone might be able to help me out.

I just recently added 2 Antminer S1 units (~400 Gh/s), but my 128 and 256 second hash rates don't seem to be showing my new hash speed correctly.  As I've had my new machines up and running for nearly 3 hours, the 3 hour average actually appears to be correct.  Is this a problem other people have had?  Or should I be doing something to resolve this?

Thanks,

So with the help of many volunteers I believe I have found the cause of the issues with KNC miners running cgminer.

cgminer seems to be "forgetting" about work if new work is not given often.  Eligius uses what I believe was an originally defined standard of 55 seconds between stratum work updates.  Work is valid for 120 seconds.  However, when cgminer doesnt get a work update every 30 seconds or so, it occasionally seems to forget the work it gave to some hashing cores and this manifests as false hardware errors.

So far three affected KNC users have confirmed that changing the work update interval to 30 seconds fixes the false HW error issue and gives a boost in hash rate.  As for tracking down the actual cgminer bug I will try to work with conman and kano on it, and hopefully keep it civil.

I will be updating the pool to do stratum work updates every 30 seconds instead of 55 seconds like it does now.  Anyone else having KNC HW error issues willing to test this before its on the live server (dev server, still get full credit for work) shoot me a PM on IRC.

I'm unsure if this issue affects non-KNC devices running cgminer as my efforts in tracking this down have been focused on KNC.

Side note, Bitminter beat us by about a second on a block earlier and it ended up throwing a failsafe.  Stats and payout queue are catching up. 

Basically, I'm going to *try* to dedicate most of this weekend to Eligius improvements.  So, more to come.

The 128/256 second hashrates rely on the reward system, and as noted in my last post, it went into failsafe mode earlier.  They should be correct in about an hour.  The 22.5 minute and longer time period hashrates should always be correct.

Excellent!  Thanks for the rapid response, I love your pool!

Will pop on IRC can test on dev

I have issues with HW ratio on Eligius on KNC Jupiter November units. I have 3 units, all of them behave exactly the same.

Testing scenario one of the units:
1. Restart cgminer, choose Eligius pool via ssh, reset cgminer statistics, let it run for couple of hours, write down stats
2. Restart cgminer, choose BitMinter pool via ssh, reset cgminer statistics, let it run for couple of hours, write down stats
3. Repeat nr 1
4. Repeat nr 2

Stats:
1. Eligius 9.4% HW, WU 8437 https://drive.google.com/file/d/0B2z0CgjT8HdwYnhkTFk1TGd1VUE/edit?usp=sharing
2. BitMinter 1.5% HW, WU 9199 https://drive.google.com/file/d/0B2z0CgjT8HdwZFB6Nkx1czBNdEE/edit?usp=sharing
3. Eligius 8.9% HW, WU 8478 https://drive.google.com/file/d/0B2z0CgjT8HdwazZsRnlPbDdYQkk/edit?usp=sharing
4. BitMinter 1.6% HW, WU 9188 https://drive.google.com/file/d/0B2z0CgjT8HdwMTJMaW1kdkNaQlE/edit?usp=sharing

I have default settings of:

Code:

[Q]ueue: 1
[S]cantime: 60
[E]xpiry: 120

wizkid057, what should I set there? I will be happy to help with dev pool, sent you PM.

I apologise if this has been covered already but I have been away for a couple of weeks and despite reading back, have found no mention of it.

Up until a couple of weeks ago, the web site would display stats, hash rate, balance etc and I could remotely check my miners were still working ok.  I received a regular payout, every few days of approx the same amount.  In my wallet, it showed as being mined.

Now, none of the stats show up (all say 0 G Hash/s/ 0 balance etc), although my miner is working fine.  I also seem to get a payout (by transfer not mined) every couple of hours (obviously much lower amount).

I have no problem with this (I would love the stats to work again) but I wanted to check it was a conscious decision to change the way the pool works rather than a bug my end!

Thanks

This makes no sense at all.  Stats have been working fine for me for months.

Hi there!

I'm also mining through Eligius pool...
Is that pool hacked? My miners are working pretty well (20GH/s), but on the stats menu there's 0GH/s... I restarted the stratum proxy, and the stats looked good for half an hour and now again dropping to 0GH/s (although my miners are working).

Help?

--- Edited:
Okay, is it right, that the stats are just not working properly, but reward is calculating correct?

Stats are still working fine for me.  Why do you think it's hacked?

Because my workers are working finde (miner webconfig is showing 20GH/s and received and accepted shares) but the eligius status page is showing 0GH/s...

Right now it's looking good, but I obviously had a dropout of half a day at the eligius pool.

And I'm wondering myself if my hashing-power has been misused...

[BobbyJo]

Entire site seems to be down and my miner has stopped.  Moved to back up!

All my miners seem to hashing fine, not down from my end 

[BobbyJo]

Can you access stats page?

[merv77]

yes stats are working fine also

[BobbyJo]

How weird.  I'm not doing anything different!  When I try and access the stats page I get:

Oh well, mining on back up for now until I can sort it out.  Thanks for the confirmation.

do you have eligius.st like below?

my butterfly have same problem
sometimes show 0 Ghash
and stats crash
