00:00:00,080 --> 00:00:06,720
folding at home is nothing new it's a distributed computing project whose goal

2
00:00:04,240 --> 00:00:11,519
is to use the idle computational power of thousands of individual contributors

3
00:00:08,880 --> 00:00:15,679
around the world to run simulations of protein dynamics in layman's terms

4
00:00:13,759 --> 00:00:19,520
whenever you're not using them your CPU or your graphics card can crunch numbers

5
00:00:18,080 --> 00:00:24,960
to help improve our understanding of biology or even develop treatments for

6
00:00:22,000 --> 00:00:30,080
diseases like cancer alzheimer's cystic fibrosis and yes

7
00:00:27,240 --> 00:00:36,000
covid19 which brings us perfectly to the purpose of today's video we actually did

8
00:00:33,200 --> 00:00:41,120
a build guide four years ago showing how to configure a pc for contributing to

9
00:00:38,960 --> 00:00:45,440
projects like this but guys the situation's a little more dire at the

10
00:00:43,440 --> 00:00:50,399
moment and we need more than just the enthusiasts who are building computers

11
00:00:47,600 --> 00:00:53,520
specifically for folding to pitch in so guys

12
00:00:51,280 --> 00:00:58,160
dig through your closets if you can find some compute it's time to put it to work

13
00:00:56,000 --> 00:01:02,719
uh here over here in the corner here my office we found a little machine that

14
00:01:00,399 --> 00:01:07,040
wasn't really doing anything else and we're gonna use this to walk you guys

15
00:01:05,040 --> 00:01:11,280
through a quick guide for how you can be up and running folding at home in what

16
00:01:09,520 --> 00:01:14,400
10 minutes 15 minutes i think this is going to take us a little longer but you

17
00:01:12,640 --> 00:01:18,240
could probably do it in 10 minutes yeah that's fair the video today is brought

18
00:01:16,240 --> 00:01:22,159
to you by ridge wallet ridge wallet wants to redefine the wallet with its

19
00:01:19,920 --> 00:01:25,439
compact frame and rfid blocking plates check out how they can help keep wallet

20
00:01:23,840 --> 00:01:35,759
bulge down and use offer code Linus to save 10 and get free worldwide shipping

21
00:01:35,759 --> 00:01:41,520
okay look i i get it especially if you guys are new

22
00:01:39,439 --> 00:01:46,000
to the channel i understand that you're wondering right now why exactly do you

23
00:01:43,759 --> 00:01:50,479
guys have a machine of this caliber quite literally lying around collecting

24
00:01:47,759 --> 00:01:56,240
dust in a warehouse it's got dual xeon platinum 8180 so those are 28 core

25
00:01:52,880 --> 00:01:58,799
processors it has six NVIDIA titan v

26
00:01:56,240 --> 00:02:04,079
graphics cards so they were built based on the very short-lived volta

27
00:02:01,119 --> 00:02:08,560
architecture so even though they're not you know rtx or whatever in terms of

28
00:02:06,159 --> 00:02:15,120
compute they're actually very similar to an rtx 2080 ti and yes that is a solid

29
00:02:12,319 --> 00:02:21,040
mass of six of them right there it used to have uh i don't know 204 384 gigs of

30
00:02:18,800 --> 00:02:24,000
RAM right now it's got quite a bit less than that but

31
00:02:22,400 --> 00:02:27,360
we scavenged the RAM out of it because it was just sitting there and that was

32
00:02:25,680 --> 00:02:30,879
easy to get at anyway the original purpose of this machine was to slice up

33
00:02:29,520 --> 00:02:36,000
the hardware resources using virtualization to have six eight core

34
00:02:34,000 --> 00:02:40,319
workstations each with its own graphics card and then have six people editing 8k

35
00:02:38,000 --> 00:02:45,360
video off of one box at the same time and then we were supposed to do a video

36
00:02:42,640 --> 00:02:51,440
showcasing the sheer might of it running just one operating system so we left it

37
00:02:47,599 --> 00:02:53,040
assembled but then we just never did it

38
00:02:51,440 --> 00:02:56,319
well today's that day we do have a couple of issues with it one of the gpus

39
00:02:54,959 --> 00:03:00,400
wasn't showing up so i want to do a quick and

40
00:02:58,160 --> 00:03:03,840
kind of reinstall them also our power supply is hanging out the back and one

41
00:03:02,560 --> 00:03:08,959
of the things that we needed for the original build this is a really really

42
00:03:06,319 --> 00:03:14,239
funky piece of computer equipment it's a it's a pci express 16x2 external adapter

43
00:03:12,640 --> 00:03:18,400
and then it goes out to a daughter board that we used to have usb cards that

44
00:03:16,800 --> 00:03:22,720
could be assigned to each one of our virtual machines we don't need that

45
00:03:20,400 --> 00:03:27,040
anymore super cool not necessary today thank you Jake i'm going to pop these

46
00:03:24,400 --> 00:03:31,440
gpus out and then plonk them back in yeah you gotta just just send her

47
00:03:29,920 --> 00:03:36,159
oh man something about this doesn't seem right

48
00:03:33,680 --> 00:03:39,440
okay seems to be in there is it possible that this will be the most powerful

49
00:03:37,599 --> 00:03:44,319
machine on the folding at-home network no because the liquid guys spun up uh

50
00:03:42,080 --> 00:03:48,959
virtualizing he said like 16 quadrant thousands okay just to flex

51
00:03:46,720 --> 00:03:52,560
mark you better be folding for LTT i mean he must be right we have a quarter

52
00:03:51,120 --> 00:03:57,920
as many members but almost the same output so oh you mean a pcmr yeah okay

53
00:03:55,200 --> 00:04:02,640
guys by the way pcmr has four times the folders that LTT does there's no excuse

54
00:04:00,480 --> 00:04:07,920
for it so let's let's let's get on that just google LTT folding team number and

55
00:04:06,159 --> 00:04:11,680
let's get let's get those numbers juiced up what we just did was add a jumper so

56
00:04:09,920 --> 00:04:15,599
that both power supplies will receive a signal from the motherboard at exactly

57
00:04:13,280 --> 00:04:20,320
the same time and turn on simultaneously the reason we need two power supplies is

58
00:04:17,759 --> 00:04:26,160
twofold number one is that these are evga's 1600 watt 80 plus titanium units

59
00:04:23,919 --> 00:04:31,120
and they simply don't make anything bigger than that the problem is that our

60
00:04:28,240 --> 00:04:36,240
gpus alone are rated at 1500 watts leaving us 100 watts for drives pumps

61
00:04:34,160 --> 00:04:39,040
cpus all that other good stuff so we were going to need two power supplies

62
00:04:38,080 --> 00:04:46,000
anyway two is that here in north america our breakers don't

63
00:04:43,280 --> 00:04:49,919
go any higher than 1600 watts plus inefficiency so we would need to plug

64
00:04:47,840 --> 00:04:55,120
into two separate circuits if we wanted all gpus and cpus firing at once which

65
00:04:53,280 --> 00:05:01,199
we do wow so just firing up doing nothing else

66
00:04:58,400 --> 00:05:04,800
it's drawing 200 and wow almost 300 watts from just one of the power

67
00:05:03,440 --> 00:05:10,160
supplies okay vga connection hey that's not what i was

68
00:05:08,560 --> 00:05:15,280
expecting did we oh god did you disconnect the oh

69
00:05:12,479 --> 00:05:18,960
no you've got to be kidding me did our boot drive come out if we do we

70
00:05:17,440 --> 00:05:22,479
trip a breaker we really do have a way of making things

71
00:05:20,639 --> 00:05:26,240
look a lot harder than they are we spent the last day troubleshooting it we

72
00:05:24,080 --> 00:05:30,639
actually eventually solved it with a motherboard swap which necessitated a

73
00:05:28,800 --> 00:05:34,560
CPU block swap which meant we had to redo all the tubing refill it anyway the

74
00:05:32,720 --> 00:05:37,600
point is it's working and this is the original board we'd actually plan to use

75
00:05:36,160 --> 00:05:42,720
for this project but there was an issue with the pci express lanes but check

76
00:05:40,080 --> 00:05:46,479
this out one two three four five six yeah so now all we need to do is show

77
00:05:44,960 --> 00:05:49,520
you guys how to install folding at home okay so to get folding at home running

78
00:05:48,080 --> 00:05:53,840
it's really simple actually we'll have a link down in the description where you can actually just download the client

79
00:05:52,240 --> 00:05:58,479
straight off their website you don't have to unzip it or anything just download it

80
00:05:56,400 --> 00:06:01,680
double click to start so by default it's actually going to

81
00:05:59,919 --> 00:06:04,880
open up a web interface now this makes it really easy to set up your identity

82
00:06:03,360 --> 00:06:09,280
so we're going to start by doing that and then later on i'm going to open up the actual program that gives you a lot

83
00:06:07,600 --> 00:06:12,639
more control over what's happening so you'll want to pick set up an identity

84
00:06:11,120 --> 00:06:16,960
because now we're going to be folding on the LTT team not for team default both

85
00:06:15,199 --> 00:06:20,560
of which is totally fine but we want you guys on our team so we can bump up those

86
00:06:18,639 --> 00:06:24,400
stats and beat pcmr so click on set up an identity and click

87
00:06:22,479 --> 00:06:28,639
start folding inside the identity tab we're going to see three things username

88
00:06:26,639 --> 00:06:34,160
team number and pass key now all of these things are important we're going

89
00:06:30,080 --> 00:06:35,280
to set our name to LMG underscore jakku

90
00:06:34,160 --> 00:06:40,720
and then team number which you can actually get from the link in the description on our forum post here it's

91
00:06:38,560 --> 00:06:44,960
two two three five one eight this will set you up on the LTT team and then you

92
00:06:43,440 --> 00:06:48,720
wanna get a pass key now this is gonna require you to enter your email and

93
00:06:46,560 --> 00:06:52,319
you'll actually get it emailed to you they use it as sort of an authentication

94
00:06:50,319 --> 00:06:54,800
so other people can't steal credit for your points

95
00:06:53,440 --> 00:06:58,560
and it gives you a bonus you'll really want to use it if you want to amp up

96
00:06:56,720 --> 00:07:02,400
those stats so once you've got your username team number and passkey entered

97
00:07:00,639 --> 00:07:06,639
just hit save and it'll start folding right away now because we want a little

98
00:07:03,919 --> 00:07:09,840
bit more control over say what CPU cores are running or when it runs we're

99
00:07:08,560 --> 00:07:13,440
actually going to open up the advanced control so down in the task bar you can

100
00:07:11,919 --> 00:07:16,880
right click on the folding app go to advanced control and it'll open up the

101
00:07:15,199 --> 00:07:20,639
actual Windows app where we can pick and choose individual gpus or what have you

102
00:07:19,039 --> 00:07:24,880
now i'm going to say that maybe i don't want my CPU to fold so we're going to

103
00:07:22,479 --> 00:07:27,680
pause our CPU and all of our gpus will be left running which is perfect and

104
00:07:26,240 --> 00:07:31,599
then i'm going to right click on the little icon down here and set it to on

105
00:07:30,080 --> 00:07:34,960
idle now that means it's only going to go on my computer is not doing other

106
00:07:33,120 --> 00:07:39,440
things i'm also going to turn the client up to full power now this means it's

107
00:07:37,120 --> 00:07:43,039
going to use as much of your CPU and GPU as possible now we paused our CPU so

108
00:07:41,520 --> 00:07:47,039
it's only going to be doing GPU but this means we're gonna get the most performance when we're actually not even

109
00:07:45,520 --> 00:07:50,880
using the computer because it's on idle only and that's basically all there is

110
00:07:48,720 --> 00:07:53,360
to it we're now folding for the LTT team we've got our pass key set up which

111
00:07:52,240 --> 00:07:58,319
means we're gonna get the most points possible and now that's all that's left is just to wait and see what kind of

112
00:07:56,560 --> 00:08:01,440
stats we push out if you want to see your stats you might notice that the

113
00:07:59,759 --> 00:08:06,160
official folding stats page i mean depending on when you watch this video might actually be down because of all

114
00:08:04,000 --> 00:08:09,440
the additional load of all the new users so we're going to actually use something

115
00:08:07,360 --> 00:08:13,840
called extreme overclocking their forum has a really great custom script setup

116
00:08:12,639 --> 00:08:18,240
so you can actually see all your stats even when the official site is down

117
00:08:16,160 --> 00:08:22,080
it will take several hours to update you can see right now our hourly production

118
00:08:19,919 --> 00:08:25,440
at least on my user is still zero but if you check back in a day or maybe 12

119
00:08:23,680 --> 00:08:29,440
hours or something you should see your points start to go up you were telling

120
00:08:26,960 --> 00:08:34,159
me about this so even though we have all these compute resources the folding

121
00:08:31,840 --> 00:08:37,519
project is struggling to issue work units so what we're only

122
00:08:36,240 --> 00:08:41,440
using one sixth of our capacity one right now

123
00:08:40,000 --> 00:08:47,040
so basically what happened is they went from 30 000 users kind of concurrently

124
00:08:44,080 --> 00:08:51,760
over the last couple years to 400 000 in the order of about two weeks so those

125
00:08:49,600 --> 00:08:54,720
servers are getting hit pretty hard and the big problem isn't so much issuing

126
00:08:53,360 --> 00:08:59,120
the work units we can actually see on this one it's stuck on send results

127
00:08:57,360 --> 00:09:03,920
waiting on send results so they actually don't have the bandwidth to take all the

128
00:09:01,200 --> 00:09:07,920
computed models and store them on their own servers right now however

129
00:09:06,080 --> 00:09:12,640
here's something cool that we want to share with you guys we are currently in

130
00:09:09,760 --> 00:09:16,560
the process of working with the folding at home project to use some of our

131
00:09:14,800 --> 00:09:22,720
bandwidth because we happen to have a 10 gigabit connection here at the office to

132
00:09:18,880 --> 00:09:24,720
run a folding at-home work unit server

133
00:09:22,720 --> 00:09:28,560
here on our premises so that's going to be our next video where

134
00:09:27,120 --> 00:09:33,360
basically we'll be able to can we preferentially issue ourselves work

135
00:09:30,320 --> 00:09:35,600
units i don't think so okay well anyway

136
00:09:33,360 --> 00:09:38,880
let's have a look at what the impact is on your system

137
00:09:36,959 --> 00:09:43,600
if you were able to run full tilt here we go this is octane bench our GPU temps

138
00:09:41,680 --> 00:09:46,720
right now are in the low 30s so that's what we would expect for water cooled

139
00:09:45,200 --> 00:09:52,320
graphics cards let's go ahead and click run so this one's only about 350 watts

140
00:09:48,959 --> 00:09:54,640
we're at 463 watts wait that's it i'm

141
00:09:52,320 --> 00:09:58,080
still at 350. so what's that 850 watts that's it on two 1600 watt power

142
00:09:56,560 --> 00:10:03,680
supplies this is great we weren't actually using that much power so i'm installing blender in the background and

143
00:10:01,040 --> 00:10:10,160
we still put up these insane numbers here's a gtx 980 for context that is

144
00:10:06,959 --> 00:10:11,920
over 20 times faster while i was doing

145
00:10:10,160 --> 00:10:14,880
stuff in the background this thing is nuts time to try something a little

146
00:10:13,680 --> 00:10:19,279
heavier oh afterburner is reporting 90 usage so

147
00:10:17,440 --> 00:10:23,839
what's our power consumption look like i've got 400 watts this time i can climb

148
00:10:21,279 --> 00:10:28,800
under though wow it's already at 720 watts what are you at 400 okay so we're

149
00:10:26,240 --> 00:10:33,120
up to 1100 watts now it still hasn't started yet oh wow yeah

150
00:10:31,279 --> 00:10:36,480
that's heavy it's getting really warm in here we literally have a thousand watt

151
00:10:34,959 --> 00:10:40,079
heater just so that's quite a lot more than octane

152
00:10:38,240 --> 00:10:43,440
but my understanding is that folding at home should actually hit it even harder

153
00:10:42,079 --> 00:10:47,279
than that yeah especially because we can use some of the CPU at the same time so

154
00:10:46,160 --> 00:10:51,360
if you were wondering if there's going to be an impact on your
