gigabyte getting into the epyc workstation market, but dunno about it for snowblossom price-wise with just one socket

Is epyc a bus or a socket or what?
Fireduck
2018-11-08 00:04:11
amd cpu
Rotonen
2018-11-08 00:04:27
8 ram channels per socket
Rotonen
2018-11-08 00:04:39
the name is stupid, but 'amd xeon' is close enough to the truth
Rotonen
2018-11-08 00:04:53
they dropped the opteron name at some point for whatever reason
Rotonen
2018-11-08 00:05:25
and they're pretty good in the way of dollars per ram channel for just the cpu
Rotonen
2018-11-08 00:07:46
the low end 120W models should do rather well for snowblossom

i love the coy jab at oracle licensing there, the use case of that processor is to be 'licensing cost optimized' :stuck_out_tongue:
Rotonen
2018-11-08 02:47:22
Got two of those. Can't use them till the riser comes tomorrow
Fireduck
2018-11-08 02:55:34
neat, I'll be interested in your results.

my mess is all on field 8 now
Fireduck
2018-11-08 18:38:05
it sucks how much less efficent it is to read from shm file system over memory allocated in the jvm
Fireduck
2018-11-08 18:38:26
but the jvm is a hot mess, so if you want to get anywhere close to system memory limit, you need to use shm
Fireduck
2018-11-08 18:40:26
what is shm
Clueless
2018-11-08 18:41:08
shared memory file system? like a ram disk?
Clueless
2018-11-08 18:41:32
Yeah
Fireduck
2018-11-08 18:48:41
It is in the linux kernel so works really well, but Arktika can't seem to access it as cheaply
Fireduck
2018-11-08 18:51:00
@Fireduck I don't understand what you mean by JVM being hot mess.
Clueless
2018-11-08 18:51:44
for example, if I want the jvm to cache 16gb, I usually have to set the max heap size much larger, like 24gb for it to work
Fireduck
2018-11-08 18:52:03
which is fine for some things, but when I want to cache 240gb on a machine with 256gb, I can't quite make that work
Fireduck
2018-11-08 18:52:15
Yeah, I wonder if it caches chunks out of order and requires room for defragging or something
Clueless
2018-11-08 18:52:33
that sort of thing is more the kernel's problem
Fireduck
2018-11-08 20:01:36
`74% to 41` yay, my code is useful
arichnad
2018-11-08 20:18:00
nice
Clueless
2018-11-08 21:05:38
@Fireduck fscache works as well as shm
Rotonen
2018-11-08 21:09:51
@arichnad yeah, it is
Fireduck
2018-11-08 21:10:26
:slightly_smiling_face: if anybody has trouble using the Dockerfile, please send them my way. i use it exclusively and everything seems to run smoothly.
arichnad
2018-11-08 21:11:36
also, i'm adrian by the way
arichnad
2018-11-08 21:12:05
yeah, I remember the pull requests
Fireduck
2018-11-08 21:12:18
I've never used docker but apparently it is hot
Fireduck
2018-11-08 21:16:50
yeah, i was expecting that mining would be slower inside the container. i figured the IO would slow down a little bit going in and out of the container. but no, i get the same hash-rate in both situations.
arichnad
2018-11-08 21:17:59
The container is a fairly lightweight construct right? It doesn't have its own kernel like full virtualization, right?
Fireduck
2018-11-08 21:18:06
more of a jail
Fireduck
2018-11-08 21:18:31
that's right. it's really just a special process. much like a chroot.
arichnad
2018-11-08 21:18:40
PIDs even show up in top.
arichnad
2018-11-08 22:37:25
depends on how you back the container and/or volume storage
Rotonen
2018-11-08 22:47:26
Anyway snowblossom reward system is more to like farming snowfield than mining maybe change the term?
Daeng
2018-11-08 22:54:43
eh, it is flailing at some thing and checking a hash
Fireduck
2018-11-08 22:54:55
nothing really to do with "mining" even in the bitcoin case
Fireduck
2018-11-08 22:55:17
but it is the term that everyone understands, do some work in hopes of making blocks to get block reward
Fireduck
2018-11-08 22:57:18
Hmm. What's the analogy?
A scavenger hunt?
Clueless
2018-11-08 22:57:29
!! Scavenger Hunt!
Clueless
2018-11-08 22:58:11
picking up dog turds, putting them in your mouth in the hopes that one is actually eventually a sausage
Fireduck
2018-11-08 22:58:33
Eww. I think that would make the documentation more confusing.
Clueless
2018-11-08 22:58:42
ah, today is one of those days where I shoudn't be allowed a keyboard
Fireduck
2018-11-08 22:59:11
Yes, you should be forced to code using text to speech.
Clueless
2018-11-08 22:59:40
I do sometimes use speech to text on android
Fireduck
2018-11-08 22:59:50
it works surprisingly well even for technical topics
Fireduck
2018-11-08 22:59:52
usually
Fireduck
2018-11-08 23:00:15
maybe that shouldn't be surprising, it was probably trained by nerds
Fireduck
2018-11-08 23:00:47
I almost have pool failover working for PoolMiner and Arktika
Fireduck
2018-11-08 23:00:57
probably get that in tonight assuming Lola goes to sleep reasonably
Fireduck
2018-11-08 23:01:40
She was really helpful in the design phase (long stroller walks were good for thinking about design)
Fireduck
2018-11-08 23:01:43
but less helpful now
Fireduck
2018-11-08 23:15:06
@Fireduck just make sure the documentation thereof does not turn political
