one other question. Along with my S9's have 14 2Pacs running on a big hub with d=256. Its been behaving fine with minimal work restarts. But since the reboot the hash isn't showing up. the rig is as its the only d=256. appears fine on my side just not displaying hash on the site
its 15pCpgJpRoYv6f1BY2Jsck2zBTBKvFBBRF if you get a chance. has been running fine for weeks until the restart. maybe just reporting issue
In this case, we had several days worth of changes/improvements ready to deploy, but an issue that we deemed important to upgrade as soon as possible for the benefit of miners was the reason we didn't give advanced notice. Ideally we want to ensure that normal updates have advanced notice, but for issues where we believe an immediate deployment is the best case for everyone then we'll use best judgment going forward.
As for the 14 2Pacs, there is a change to diff that we implemented which could be causing that. I'll go ahead and look into it further to see if tuning the difficulty down in the range of the 2Pacs can be accomplished without hurting S9s and capabilities of that nature. I can manually make a change now and if you wouldn't mind giving me performance feedback tomorrow after it has had some time for you to see results, I can then tune it further to optimize things.
Update: We made another change based on your feedback, so apologies that it probably knocked your MRRentals again, but based on what I'm seeing so far, it seems to be a decent health improvement for S9s based on difficulty. That being said we are going to spend more time the next few days coming up with a plan on how best to allow the 2Pacs and devices of that nature. With the current network situation of all sha256 coins, we want to make sure that finding blocks is efficient and as profitable for miners as we can make the pool from our end. The changes we made today allow smoother operation of S9s, Nicehash rentals and further tech as network difficulty keeps rising. I'll continue monitoring and adjust as I can to benefit you and others on the pool, at the same time we won't restart unless necessary from this point forward.
everything is set to 100k on sha. I will keep an eye on the S9s and 2pacs. Have about 130 thz at moment on SHA so more interested in the S9s
**** Update ***. Read it wrong. looks like all SHA is forced to 1M diff. going to fire up a couple of T9s also and see how it goes. will leave 2pacs on for weekend but at 1m they are going to be pretty ineffective. Interesting though - the pool set the 2pac rig at 125m and getting restart every min or so. The website doesn't seem to be showing hash rate for a lot of rigs. they are listed but no hash. Maybe just a lag.
**** Update ****. MRR rigs dropping like flies - they are just hanging. Not sure what happened. They are all S9 clusters. But have had 3 of them gomdark in last 15 min. They had been running fine for 3 weeks on your site. might want to look into this. Not sure if its the MRR layer or what but rigs that had been stable now won't hash. A few would finally pickup after few minutes. Moved the others over to Slush and will try again later.
