hashrate distribution looks much better now.

@fydel I suggest a bar graph instead of piechart for visual distinction. :P
2018-11-02 12:29:38
fydel
the chart is from @finex’s pool.
2018-11-02 12:30:22
fydel
but i am thinking to switch from munin to google charts too.
2018-11-02 14:18:13
Rotonen
some history view of block accumulation of the pools would be fun
2018-11-02 14:38:47
Clueless
@Rotonen that's a perfect stat for me to chart. :)
2018-11-02 15:26:08
Rotonen
yeah just a counter per unique block remark since epoch block
2018-11-02 15:26:39
Rotonen
some subleties in how to stack them
2018-11-02 15:27:07
Rotonen
especially in regards to time scaling
2018-11-02 15:41:31

@Rotonen so I have a reorging python daemon now that I can just leave running forever to do work and updates, I'm tallying up some data I should report on, so please let me know if you have other ideas. :)
2018-11-02 15:42:18

I also wanted to ask you if you might help me choose components for mining. I'm thinking 8+ NVME SSDs networked with ryzen processors.
2018-11-02 16:01:13
Rotonen
just get a dual docket epyc for that money
2018-11-02 16:46:32
Fireduck
@Clueless what is your budget for mining and what field do you want it to work for?
2018-11-02 16:46:48
Fireduck
If you want to drop $6k, I have a solid plan for networked memory mining clusters.
2018-11-02 17:04:30
Clueless
@Fireduck That sounds about right, and it'll give me a reason and the tools to figure, test, and document arktika thoroughly, then I'll be prepared to help people more.
2018-11-02 17:13:11
Fireduck
sure
2018-11-02 17:13:20
Fireduck
arktika needs some work on feedback and diagnostics
2018-11-02 17:13:31
Fireduck
if you get it wrong it is really hard to tell wtf is going on
2018-11-02 17:14:58
Fireduck
that is my 128gb plan, use three of those so you have room for OS overhead and it should be able to handle the 256gb field just fine
2018-11-02 17:15:09
Fireduck
and if you want to go to 512gb field, just add more nodes
2018-11-02 17:15:18
Fireduck
(or whatever node size is most cost effective at the time)
2018-11-02 17:15:31
Fireduck
might need to add 10gb networking
2018-11-02 17:18:46
Fireduck
plus you should be able to attach networked worker nodes, assuming you have spare network bandwidth
2018-11-02 17:18:52
Fireduck
but I haven't tried any of this yet
2018-11-02 17:25:17
Fireduck
I really need to get a new power circuit or two run for my server room.
2018-11-02 17:52:05
Rotonen
just get a dual socket eight channel ram monster with 768GB RAM
2018-11-02 17:52:25
Rotonen
eight channels per socket, mind you
2018-11-02 17:52:36
Fireduck
I don't even know where to get that sort of hardware.
2018-11-02 17:52:47
Rotonen
from a shop
2018-11-02 17:53:01
Fireduck
Ha. How much would it cost, roughly?
2018-11-02 17:53:18
Rotonen
ram plus 1,5k
2018-11-02 17:53:46
Fireduck
RAM is a lot. I assuming it is some sort of ECC registered ram made mostly of unicorn tears
2018-11-02 19:05:18
Rotonen
price per hash for 512GB is decent
2018-11-02 19:08:30
fydel
what cpu?
2018-11-02 19:09:24
fydel
ddr3?
2018-11-02 19:11:04
Rotonen
2x epyc, ddr4
2018-11-02 19:11:35
fydel
how much mh/s?
2018-11-02 19:12:09
Rotonen
should land one around 4MH/s
2018-11-02 19:12:25
fydel
but 6k$ or what? wow.
2018-11-02 19:12:39
Rotonen
but to sustain that at 512 is a lot more than to sustain that now
2018-11-02 19:13:42
fydel
what is the watt draw?
2018-11-02 19:16:24
Rotonen
as low as 155W per socket https://www.amd.com/en/products/epyc-7000-series-2-socket-models Built with the AMD EPYC™ SoC, 2 socket server solutions effectively manages all database, hybrid clouds environment and virtualized workloads. It also features 64 cores, 4 TB of memory, and 128 lanes of PCIe® connectivity. Find out the various models and its specifications. Explore more!
2018-11-02 19:18:09
Rotonen
and upgradable up to 2TB fields, but *that* gets expensive
2018-11-02 19:18:46
Rotonen
something like 2,5k for the ram, it would seem?
2018-11-02 19:19:14
Rotonen
so 4k?
2018-11-02 19:19:37
fydel
what board did you choose?
2018-11-02 19:20:52
Rotonen
supermicro H11 is what i would go for
2018-11-02 19:22:14
fydel
neat
2018-11-02 19:22:19
Rotonen
@Fireduck where’d your 6k plan get someone?
2018-11-02 19:23:21
fydel
i was thinking the last couple of weeks about what to buy.
2018-11-02 19:23:26
Rotonen
probably a larger short term hash rate
2018-11-02 19:23:27
fydel
EPYC is neat.
2018-11-02 19:23:51
Rotonen
yeah, a bit weird as some cores have less channels, but still plenty of channels
2018-11-02 19:24:39
Rotonen
epyc or ibm power are the high end affordables currently
2018-11-02 19:27:29
fydel
i bought an old hp server now. it will arrive on monday.
2018-11-02 19:27:48
fydel
43kg. fml.
2018-11-02 19:33:17
Rotonen
get a bierrodel as well
2018-11-02 19:43:22
fydel
ja. maybe.
2018-11-02 19:43:49
fydel
i live in on 4 floor. no escalator.
2018-11-02 19:47:33
Rotonen
then you need a 3 wheel model
2018-11-02 19:48:01
Rotonen
once carried a 5U oracle server up 4 floors - never again
2018-11-02 19:53:40
Fireduck
My $6k was 3 $2k nodes with 128gb ram each. Haven't actually built it so not sure how well it would perform.
2018-11-02 19:54:27
Rotonen
meh
2018-11-02 19:54:49
Rotonen
a dual socket board with processors and ram sounds cheaper and less effort
2018-11-02 19:55:25
Fireduck
probably, and add in 10gb network link and you can attach worker nodes until you are using all the memory bandwidth that it can manage
2018-11-02 19:58:40
Rotonen
the switch you need is probably gonna cost you 2k
2018-11-02 19:58:44
Fireduck
ok. newegg has like on SP3 board. Where the hell do I find real server hardware?
2018-11-02 19:58:55
Rotonen
at some point you hit a packet density limit on the switching speed
2018-11-02 19:59:23
Rotonen
dunno how you do that in the states, but in europe there are like n+1 enterprise vendors
2018-11-02 20:00:09
Rotonen
oh, supermicro sells directly there, that explains some
2018-11-02 20:00:42
Fireduck
just need a 10gb uplink port, workers will be 1gb, which lets a worker do about 1mh/s
2018-11-02 20:01:06
Rotonen
i'd not touch netgear, check out what some real vendor can give you
2018-11-02 20:01:36
Fireduck
I've had good luck with dumb netgear switches
2018-11-02 20:01:43
Rotonen
so you want some aggregation switch https://www.ubnt.com/unifi-switching/unifi-switch-16-xg/ The US‑16‑XG completes your UniFi ecosystem, with centralized aggregation totaling 320 Gbps.
2018-11-02 20:01:44
Fireduck
I wouldn't get a netgear router
2018-11-02 20:01:50
Rotonen
yeah, you want your switches as dumb as possible
2018-11-02 20:05:46
penfold
I have a netgear switch that regularly “crashes” if you use all 8 ports
2018-11-02 20:05:49
penfold
great feature
2018-11-02 20:06:06
penfold
meanwhile cheapo TP-Link never skips a beat
2018-11-02 20:06:20
Rotonen
that sounds like a ground level trip up - the power supply is not grounded?
2018-11-02 20:06:22
Fireduck
ha. These days I am less picky, I mostly use switches that I find in boxes around my house.
2018-11-02 20:06:49
Fireduck
I have a cisco that came with my house that hates packets. I've mostly moved off that.
2018-11-02 20:06:51
penfold
@Rotonen after about the tenth time wondering why the internet wasn’t working on some devices and not others I replaced it… not worth the hassle :smile:
2018-11-02 20:07:09
Rotonen
fair enough
2018-11-02 20:07:43
Fireduck
Basically a disaster
2018-11-02 20:08:29
Fireduck
To be fair, those bottom shelves are crap that came with the house that are slightly too nice to throw away but not really worth selling
2018-11-02 20:08:36
Fireduck
I should just toss the lot of it
2018-11-02 20:08:59
Rotonen
your pet octopus looks to be doing well
2018-11-02 20:10:24
Fireduck
I pay enough money for slack, might as well use it to send you guys pictures
2018-11-02 20:16:45
fydel
i ike the wallpaper. :stuck_out_tongue:
