@Rotonen @Fireduck
I'm ready to build that mining machine.
I'm thinking 2-3 of these
4x pcie nvme card Link: http://a.co/d/gN0TzDq
8x samsung 970 evo 500GB or 1TB Link: http://a.co/d/6zQmata
Total so far $2100
Need to pick out motherboard(s), cpus, ram

don’t get high power SSDs, dont’t get SSDs with lesser channel counts, that hyperx only works with intel nvme, but then you should do VROC

Rotonen

in miner what does this mean: INFORMATION: Probably code EBCAK ?

that's really sassy.

naughty

i like your humor. but that's not really helpful.

fydel
2018-11-05 17:09:29
Agreed

Fireduck
2018-11-05 17:09:44
But it tells you that you have a pool

Fireduck
2018-11-05 17:09:51
So it is a local problem

Fireduck
2018-11-05 17:09:52
could it be a broken snowfield? i am just setting a new server.

fydel
2018-11-05 17:10:01
Arktika or PoolMiner?

Fireduck
2018-11-05 17:10:06
poolminer

fydel
2018-11-05 17:13:24
That will test all the fields on start up and it will tell you which ones are working and which are not

Fireduck
2018-11-05 17:13:53
ah. okay.

fydel
2018-11-05 17:23:05
@Rotonen I wasn't going to bother with tattoos, as I figured it would add overhead.
In which case. I thought it'd still work with other NVME?

Clueless
2018-11-05 17:29:28
Face tattoos ?

@Clueless reports seem to vary, read <#CB4CYRTPG|mining> from discord from over the weekend

Rotonen
2018-11-05 18:06:54
@Rotonen Well, I can always send it back and try something else if that doesn't work.

Clueless
2018-11-05 18:07:50
since the larger drives are faster, I think I'd go with those.

Clueless
2018-11-05 18:24:17
at least with the 960 pro, only the 2TB model is actually sustainably fast - i’m a bit sceptical of samsung here

Rotonen
2018-11-05 18:25:11
from intel, the 760p looks pretty good, though, especially if on VROC

that seems to mostly ride on bypassing pcie switching with some bus level hardcoding

So 56kh/s

Fireduck
2018-11-05 18:33:29
I'm confused, should I use VROC?

Clueless
2018-11-05 18:34:03
and should I be thinking 56KH per NVME SSD?

Clueless
2018-11-05 18:35:20
maybe I should just do a DDR3 ram machine

You can get 128GB (4x32) for $800

@SidGrip are you making the memory bus of your existing one?

Fireduck
2018-11-05 18:37:29
Might want to try adding arktika worker nodes to it if not

Fireduck
2018-11-05 18:39:29
I did have it setup with another 148GB server using arktika but the other server doesn't make up the difference in hash rate loss when using arktika on the main miner

SidGrip
2018-11-05 19:16:54
@Clueless as far as i can tell VROC uses your cpu as the ssd controller, directly driving all the nand channels, thus skipping a middle man

Rotonen
2018-11-05 19:18:05
@Fireduck i’m having a hunch VROC can squeeze more than the dinky little arm on the ssd, but seeking verification

Rotonen
2018-11-05 19:19:17
@SidGrip how many sockets is that? seems like a quite the winner

Rotonen
2018-11-05 19:24:37
mobile ebay sucks, dual socket quad channel

Rotonen
2018-11-05 19:24:38
It's 4 socket quad channel, the one I have running gets over 3 M/hash and does 2.8 M/hash running arktika

SidGrip
2018-11-05 19:24:44
oh?

Rotonen
2018-11-05 19:24:58
also you could find these cheap

@SidGrip any guesses as to what’d limit arktika? that gap is sadly close to 7/8

Rotonen
2018-11-05 19:36:26
I don't know if I understandthe question, I remember asking @Fireduck a while back about arktika and he said there was performance loss. I am currently running snowfield 9

SidGrip
2018-11-05 19:42:02
@SidGrip tcp/ip has 1/8 of the packet as overhead

Rotonen
2018-11-05 19:42:14
Artika has a bit of I'm memory enquue and dequeue operation

Fireduck
2018-11-05 19:42:40
Which involves a bit of locking

Fireduck
2018-11-05 19:42:50
that sounds more plausible than the clown college i suspect

Rotonen
2018-11-05 19:43:03
So not surprised there would be perf impact, especially on multicore

Fireduck
2018-11-05 19:43:20
Multisocket I mean

Fireduck
2018-11-05 19:43:46
The lock stuff will probably always be in cache of other prcoccesor or something

Fireduck
2018-11-05 19:44:23
if that lock exists in an another numa zone, the access penalty on acquiring and releasing can be rough

Rotonen
2018-11-05 19:44:29
I should make a thread local optimized queue implementation

Fireduck
2018-11-05 19:44:57
please do, that’d play beautifully into cuda

Rotonen
2018-11-05 19:45:20
i’m thinking of gpu memory as a sacrificial cache in that case

Rotonen
2018-11-05 19:45:39
I'll have to think about it

Fireduck
2018-11-05 19:46:52
Not as easy as the thread optimized atomic long I wrote last week
