Just refreshed this thread, noticed the title changed from [4000 GH] to [5000 GH].

 Grin

It may just be temporary, but I have to celebrate my victories as they happen Smiley.

BTC Guild may finally make the top of the weekly hashrates - bridesmaid no more Wink

Care to share what happened?

I can't say who it is, but the age of ASICs has finally hit with more than a single 60 GH/s unit to show for it.  Hopefully the luck bounces around, today was pretty bad overall, but early in the week was good.  Very hopeful to see how next week's charts look Smiley.

I'm going to give credit to Jeff Garzik's quote:  [17:57] <jgarzik> Eleuthria: ASIC miner is most stable when mining on your stratum ;p
rather disapointed he didn't try a larger sample before making that statement

@Eleuthria:

Are there a lot of PPLNS shifts where there is 0 blocks found? I switched to PPLNS today and it seems my luck (the pools really) isn't so great.

There has only been one shift to ever have 0 blocks before it matured [a block that took over 30 million shares].  Note that the shifts in Green at the top are not yet completed, they will continue to get blocks paid to them until they have expired.  Luck was pretty bad most of last night/this morning, but picked up (couple of shifts just matured that paid above 100% PPS).  Current shifts are still in the neutral luck range (next shift to finish is slightly above PPS).

Bad luck has put a distaste in my mouth in regards to this pool. I have finally gotten sick of running my mine for hours with no payout, then hours after I stop and game on my computer there are like 3 blocks solved... Back to PPS I guess, I least I know what I'm going to get.

Depending on the performance results (specifically looking at the time it takes for bitcoind to return information needed for a new block), other servers may migrate to solid state drives/bare hardware in the future.

Did you consider SSD lifetime? I've been running on SSD RAID for a year, but I didn't have good feeling from that SSD setup. Especially RAID of two SSD from the same vendor and the same age doesn't have too much sense.

I migrated to standard HDD RAID + blockchain in RAMdisk + periodic HDD snapshots. It's even faster and seems to be a safer solution.

My shares per shift is going down coinciding with the overall pool hash going up and not by a negligable amount.

I am getting at least 40% less shares consistently than when the pool hash was between 3-3.5K. Sad

Also a month or two back where all miners had to restart their machines/proxy to reconnect I was getting +25% shares per shift consistently until miners reconnected.

Sorry but I may have to switch pools. I'd rather not as I have the least problems with your pool, but a little hassle is better than a 1-3% fee and a 40% share loss.

If I understand you correctly, that is the expected behaviour for PPLNS. As the hashrate increases, you get fewer shares per shift, but the same number of shares per day and the same number of coin per week.

Yes, with the increase in hash speed, shifts are now being closed about 25% faster, meaning your shares per shift will be ~25% lower than before.  However, you will be participating in more shifts overall, and the blocks per shift shouldn't change (outside of the regular variance), so the payments should be similar for each shift, and for a 24-hour period.

Right now I'm leaving the PPLNS settings alone, but I will be looking into extending the 'N' value if difficulty hits 4~5 million, to lower the odds of shifts with 0 blocks found and help smooth the per-shift variance back down to the original levels.

BTC Guild website host node is acting up again.  Working on a fix.  All stratum servers are working fine.  One getwork server may be having slow performance since it shares a node with the website.  Will update shortly.

What a surprise.  DDoS attack.  Will update again shortly.


UPDATE1:  It's not completely taking things offline, it's mostly affecting the website.  As best I can tell, most Stratum servers are still functioning.
UPDATE2:  Things seem to be back to normal.  Waiting on an email from the datacenter to find out more about it.
UPDATE3:  Total downtime was ~15 minutes (less for most servers).  Everything is back to normal and the datacenter has my servers on watch tonight with instruction to call me immediately if something happens again.

Does the datacenter filter for you or blackhole and then change ip?
If filter... Is it costing you a lot?

It's a mix of both.  They can filter some attacks, while others are blackholes.  It's one of the reasons my colocated servers there run with virtualization, it makes it very easy to migrate the services over different IPs when blackholes are required.  I've actually got two extra subnets already reserved at the DC for my use that I can switch to if an attack ever targeted my current subnet ranges.

Higher payouts are a factor of MASSIVE luck today Smiley.  But with this user in the pool, it should help shrink the daily variance a bit.

User 67117 has now become the first connection on Stratum to reach a 4-digit variable difficulty.

[00:39:31] Increasing [obfuscated]'s difficulty to 1024!


What does that mean?  It means somebody mining at 1.5+ TH/s is using roughly as much bandwidth and server resources as a miner running a graphics card over Stratum, and LESS bandwidth than a graphics card using the outdated getwork protocol.

Sounds great!

Do you use the client.get_version command with your stratum implementation? It would be interesting to know what software they apparently run.

I've not added client.get_version yet.  It's one of those commands that offers fairly limited use.  I'll probably add it in the coming weeks as I continue to work on more diagnostic utilities in my Stratum code.  I do know that they are using a Stratum Proxy (most likely slush's proxy) to run all their workers through one connection.

Good to know that the proxy can handle such load :-).
