IRC logs of #boinc for Saturday, 2012-12-08

00:12 *** efc has joined #boinc

00:17 <PovAddict> moo efc

00:19 <efc> Moo

00:19 <efc> Getting GTX560 out of the box..

00:19 <efc> this is my first leafblower card

00:20 <PovAddict> lol

00:22 <PovAddict> efc: RomW and Tank_Master are testing fresh new BOINC support for OpenCL on Intel GPUs (Ivy Bridge)

00:25 <efc> I just got one. maybe they can crash on mine, once its going.

00:25 <RomW> latest drop is here:

00:26 <efc> These cards should really take their own external power plug.

00:26 <RomW> lol

00:27 <PovAddict> efc: triple-phase?

00:28 <efc> sure, wouldn't want to trip the 240volt breaker

00:29 <PovAddict> efc: then you can also avoid the starter capacitor on the giant AC-powered fan motor! ;)

00:33 <efc> its nice not having PATA cables but the extra power to everything makes a bigger mess

01:01 <Tank_Master> 12/7/2012 9:54:48 PM | | INTEL GPU 0 (ignored by config): (version , 0MB, 0 GFLOPS peak)

01:01 <Tank_Master> latest test could do better :P

01:03 <efc> So this new doodad could use my otherwise idle integrated graphics?

01:03 <Tank_Master> depends on the mobo and your setup

01:04 <Tank_Master> on mine, the main desktop HAS to be the intel display otherwise nothing will detet the gpu

01:05 <Tank_Master> not even having it pluged in was enough

01:05 <efc> Ah.. I got an addon card. Still should be useful.

01:05 <Tank_Master> yeah, i got an addon as well

01:05 <Tank_Master> (2 actually)

01:05 <Tank_Master> would be nice if i didnt need a monitor pluged in to use the intel gpu

01:08 <Tank_Master> i still lol at

01:08 <Tank_Master> 12/7/2012 9:54:48 PM | | OpenCL: INTEL GPU 0: Intel(R) HD Graphics 4000 (driver version, device version OpenCL 1.1, 1624MB, 1624MB available)

01:08 <Tank_Master> defently not detecting the dedicated memory

01:09 <Tank_Master> and whats also interesting is the max setting in the bios is 1gb

01:11 <RomW> Does the gpu caps viewer report the correct numbers?

01:12 <Tank_Master> gpucaps reports the same

01:12 <Tank_Master> 1.6gb

01:12 <Tank_Master> im assuming its just how the driver is reporting the avalible memory

16:41 <zombie67> hi pov

16:41 <zombie67> I see the latest version of boinc sees my intel HD 4000 GPU

16:42 <zombie67> so I guess rom got access to an ivy bridge machine?

16:42 <PovAddict> zombie67: afaik Charlie wrote the code blindly and Tank_Master tested it

16:42 <Tank_Master> i was up till 1AM last night testing them

16:43 <zombie67> sweet

16:43 <zombie67> now we just need slicker to build an app

16:43 <Tank_Master> now they are adding hooks into the server

16:43 <PovAddict> zombie67: the release has a few bugs (now fixed), such as reporting the Intel GPU as ATI :)

16:43 <Tank_Master> haha yeah

16:43 <Tank_Master> that was great

16:43 <PovAddict> 12/7/2012 6:53:54 PM | | OpenCL: ATI GPU 0: Intel(R) HD Graphics 4000 (driver version, device version OpenCL 1.1, 1624MB, 1624MB available)

16:44 <zombie67> ?, did you have to add any intel OpenCL drivers?

16:44 <zombie67> to make BOINC see it?

16:44 <PovAddict> zombie67: apparently the Intel OpenCL driver only sees the GPU if you're using it as the main display

16:44 <Tank_Master> i just installed the intel GPU drier, which also installs the OpenCL SDK

16:44 <zombie67> but did you *have* to?

16:45 <Tank_Master> dunno, i didnt see the option to not to install the sdk

16:45 <Tank_Master> 12/8/2012 12:38:32 AM | | INTEL GPU 0: (OpenCL only) Intel(R) HD Graphics 4000 (version, 1624MB, 1624MB available, 45 GFLOPS peak)

16:45 <Tank_Master> 12/8/2012 12:38:32 AM | | OpenCL: INTEL GPU 0: Intel(R) HD Graphics 4000 (driver version, device version OpenCL 1.1, 1624MB, 1624MB available)

16:45 <zombie67> I installed the latest on a machine, and it saw it no problem.  But I can't recall if I installed it or not.

16:46 <PovAddict> Tank_Master: that's from Rom's unreleased binaries, right?

16:46 <Tank_Master> only way i got it to work was to set the monitor hooked into the Intel GPU as the main disp;lay

16:46 <zombie67> I installed it on my macbook pro, but it does not see my HD 3000

16:46 <Tank_Master> yes, its unreleased

16:47 <Tank_Master> will be included in the code for the version update on monday

16:47 <zombie67> .40 on /dl sees OpenCL on my windows machines

16:47 <PovAddict> zombie67: do you know of any generic OpenCL testing software for Mac?

16:47 <Tank_Master> yeah, but not for intel

16:48 <PovAddict> like GPU Caps Viewer?

16:48 <zombie67> .40 sees my hd 4000 on my windows machines

16:48 <zombie67> pov, no, I am not familiar with OpenCL on mac at all.

16:49 <Tank_Master> how? the code for that wasnt added to .40

16:50 <zombie67> I can show you.  hold on

16:50 <PovAddict> yes it was

16:50 <PovAddict> Tank_Master: the first thing you tested was unmodified 7.0.40 :P

16:50 <PovAddict> it's reporting as ATI and other garbage, but it works

16:51 <zombie67> nm, I'm an idiot

16:53 <zombie67> looking at wrong machine

16:53 <zombie67> 12/8/2012 6:51:21 AM |  | Starting BOINC client version 7.0.40 for windows_x86_64

16:53 <zombie67> 12/8/2012 6:51:21 AM |  | Processor: 8 GenuineIntel         Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz [Family 6 Model 58 Stepping 9]

16:53 <zombie67> 12/8/2012 6:51:21 AM |  | OpenCL: ATI GPU 0: Intel(R) HD Graphics 4000 (driver version, device version OpenCL 1.1, 1624MB, 1624MB available)

16:54 <PovAddict> see, that works

16:57 <zombie67> I just sent slicker a message.  He was going to build an app for collate, but wasn't willing to spend the time until I could get boinc to see the HD 4000

16:57 <zombie67> tank_master, will it also see the HD 3000?

16:59 <zombie67> also, you mentioned that you had to have the monitor attached to the HD 4000 GPU.  Does that mean using the connector on the mono instead?  Will a dummy plug work?

17:00 <Tank_Master> it will see whatever the intel driver supplies

17:00 <Tank_Master> a dunny wouldnt work becaue then you wont see the windows that open up on the main screen

17:00 <zombie67> I VPN into my machines

17:01 <zombie67> no monitors at all

17:01 <Tank_Master> i dont know what will happen in that instance

17:01 <Tank_Master> its not enough to just have a monitor pluged into it

17:01 <Tank_Master> its got to be the mina display

17:01 <zombie67> what windows do I need to be seeing?

17:02 <Tank_Master> boinc?

17:02 <Romulus> It has been said that boinc is designed for high throughput, not low latency, Tank_Master

17:02 <Tank_Master> forget boinc

17:02 <Romulus> 10-4.

17:03 <zombie67> SB is hd 3000, right?

17:03 <Tank_Master> yes

17:03 <zombie67> my macbook pro has HD 3000 and a Radeon HD 6750M.

17:03 <Tank_Master> 2000/3000 for SB

17:04 <zombie67> maybe I can get them both crunching.

17:04 <Tank_Master> 2500/4000 for IB

17:04 <Tank_Master> pokes RomW

17:05 <PovAddict> zombie67: with the messages you're getting, you should be good to go

17:05 <Tank_Master> the server will needs updating to handle the messages requesting work for intel

17:08 <zombie67> I'll let slicker know

17:08 <Tank_Master> rom sent off my logs to someone else to add the server support

17:09 <Tank_Master> but theres more work to be done on both

17:10 <zombie67> sure

17:10 <Tank_Master> id say its still to early to get slicker involved

17:11 <zombie67> the app needs to be built, and that can be done without server support

17:13 <RomW> It turns out David had written some of the needed server side stuff awhile back

17:13 <RomW> I ended up breaking the server build last night

17:13 <RomW> :)

17:13 <RomW> I think David fixed that

17:13 <Tank_Master> lol

17:14 <RomW> As well as made a couple other tweaks to the Intel detection code on the client

17:14 <RomW> I'm posting a new private drop

17:19 <zombie67> I'm really excited about this.  There is a lot of idle resources out there, and growing.

17:20 <RomW> Well, I think we are going to have to get more info from Intel though

17:20 <Tank_Master> 12/8/2012 2:19:57 PM | | INTEL GPU 0: (OpenCL only) Intel(R) HD Graphics 4000 (version, 1624MB, 1624MB available, 45 GFLOPS peak)

17:20 <zombie67> oh?

17:20 <Romulus> hmm... oh are you actually there during the eq, zombie67

17:20 <Tank_Master> 12/8/2012 2:19:57 PM | | OpenCL: INTEL GPU 0: Intel(R) HD Graphics 4000 (driver version, device version OpenCL 1.1, 1624MB, 1624MB available)

17:20 <RomW> 45GFLOPs peak for an HD4000 seems kinda light to me

17:20 <Tank_Master> forget oh

17:20 <Romulus> Gotcha!

17:21 <Tank_Master> well, thats at 350Hz, its real speed is over a GHz i think

17:21 <zombie67> is that 45gflops actual performance?  or claculated?

17:21 <RomW> calculated based on what OpenCL reports to us

17:22 <RomW> But there are two features Intel uses to adjust clock rates for extending battery life, we cannot get that info from OpenCL

17:22 <zombie67> ah.  Yeah, it is probably under-reporting.  On my AMD cards, they down-clock when no under load.

17:22 <zombie67> maybe intel does the same?

17:23 <Tank_Master> nvidia downcloads on low or no load as well

17:23 <Tank_Master> yes

17:23 <RomW> yup

17:23 <zombie67> so maybe a multiplier needs to be added to the calc?

17:23 <Tank_Master> only workaround i can think of is to laod the gpu, then ask for its speed

17:26 <zombie67> but aside from the underreporting of the GPU performance, any other issue?

17:26 <Tank_Master> amount of memory openCL reports is funny

17:26 <Tank_Master> 1.6GB

17:26 <Tank_Master> for the intel gpu

17:27 <zombie67> anything that actually prevents work?  Or causes data corruption?

17:27 <Tank_Master> how would we know?

17:27 <Tank_Master> :P

17:27 <Tank_Master> this hasnt been tested yet

17:28 <zombie67> Heh.  I thought you were running dummy tasks or something

17:28 <Tank_Master> no

17:28 <Tank_Master> just testing if it was reporting right and asking for work

17:28 <Tank_Master> reporting the intel GU info that is

17:29 <zombie67> got it

17:29 <Tank_Master> 12/8/2012 2:20:12 PM | orbit@home | [sched_op] CPU work request: 255265.60 seconds; 0.00 devices

17:29 <Tank_Master> thats the other part that was added last night

17:30 <zombie67> this is so cool

17:37 <PovAddict> RomW: 45 GFLOPS is the fallback if it fails to calculate the real thing

17:38 <PovAddict> RomW: peak_flops =  (x>0)?x:45e9

17:42 <PovAddict> Tank_Master: do you get any clGetDeviceInfo warning?

17:43 *** Aeternus has joined #boinc

17:44 <PovAddict> hmm no

17:44 <PovAddict> if you did, BOINC would skip that device

17:48 <RomW> @Pov, if you run through the calulations manually you get the same value when clock rate is 350Mhz and execution units is 16 i believe

17:49 <PovAddict> hmm yes

17:50 <PovAddict> 44.8

17:51 <PovAddict> but 350MHz doesn't sound right at all

17:51 <RomW> It is what OpenCL is reporting

17:57 <Tank_Master> not that i recall, pov

17:57 <Tank_Master> 350 is the speed its at when idle

17:58 <Tank_Master> so for soem reason the intel gpu is reporting the actual speed and not the peak speed

18:17 *** efc has joined #boinc

18:26 <zombie67> according to this, desktop chip is 650-1150.

18:26 <zombie67>

18:26 <Romulus> <> (at

18:27 <zombie67> it lists mobile as 350-1300

18:27 <PovAddict> flops or clock rate?

18:27 <zombie67> clock

18:27 <PovAddict> well Intel is Doing It Wrong if it reports 350

18:28 <PovAddict> the information is called CL_DEVICE_MAX_CLOCK_FREQUENCY

18:28 <zombie67> maybe the table on the wiki page is backwards?

18:28 <PovAddict> so it should be reporting 1150 or 1300

18:28 <zombie67> yeah

18:30 <zombie67> according to the formula in the footnotes, the HD 4000 desktop should be about 147 gflops

18:31 <PovAddict> zombie67: BOINC's formula is max_compute_units * 8 * max_clock_frequency * 10^6

18:32 <zombie67> wiki page forumula:

18:32 <Romulus> <> (at

18:32 <zombie67> whoops

18:33 <zombie67> The raw performance of integrated GPU, in single-precision FLOPS, can be calculated as follows: EU * 4 [dual-issue x 2 SP] * 2 [multiply + accumulate] * clock speed. For example, the HD Graphics 3000 is rated at 125 GFLOPS,[55] which is consistent with the formula (12 * 4 * 2 * 1,300 MHz).

18:33 <PovAddict> oh

18:33 <zombie67> HD 4000 has 16 EU

18:33 <PovAddict> a code comment quotes that actually

18:34 <PovAddict>

18:34 <Romulus> <> (at

18:34 *** Psychoholic has joined #boinc

18:35 <PovAddict> so BOINC is assuming [dual-issue x 2 SP] and [multiply + accumulate] are 1

18:36 <zombie67> so the HD 4000 ~ the same as the Radeon HD 6450M, using the same formula

18:36 <Tank_Master> not to bad...

18:45 <zombie67> it is odd that the mobile chip has a higher clock for the GPU.  That has to be backwards, right?

18:45 <Tank_Master> nope

18:45 <Tank_Master> cus its more expected for desktops to have descreet GPUs

18:46 <PovAddict> discrete*

18:46 <PovAddict> zombie67: not necessarily; perhaps using a smaller manufacturing process (needed to reduce power) lets them get away with a higher clock without burning up

18:47 <Tank_Master> laptops are typically designed more for power effecency, so using the ondie GPU is perfered, even it it's varent uses more power, for it would be less power than a discrete gpu

18:47 <zombie67> but mobile has bigger problems with heat and battery life

18:47 <zombie67> hm

18:47 <PovAddict> simple

18:47 <PovAddict> find Intel-official info and fix wikipedia :)

18:48 *** FnorZ has quit IRC

18:48 <zombie67> finding info on intel's site is impossible sometimes

18:48 <zombie67> but I will look

18:48 <PovAddict> perhaps the cited links on wikipedia are a good start

22:59 <PovAddict> ?

23:08 <zombie67> just making a follow on joke to TMs comment

23:15 * efc downloads a modern BOINC.. slooooowly

23:17 <PovAddict> are you still in the dark ages of internet?

23:18 <efc> Please wait while I download your latest IRC message.

23:19 <efc> In other news, a friend leaving the country needed to get rid of old computing stuff, so he sent me a box full of parts. Soon, my numbers will grow again.

23:20 <efc> And thats not counting the total of seven (7) 386s here.

23:20 <zombie67> next you tell me about how you crunch over ham radio

23:43 <efc> I've considered it for various reasons.. max speed allowed is 19.2kpbs, maybe less on some bands

23:54 <zombie67> heh

23:54 <zombie67> next is sneakernet

23:57 <PovAddict> zombie67: don't underestimate the throughput of a truck loaded with tapes driving through a highway!

23:57 <zombie67> yeah, someone did a comparison about 5 years ago

23:57 <PovAddict> I read that Amazon S3 supports sneakernet for initial data loads

23:58 <zombie67> netflix (at the time) had more bandwidth with DVDs in the email than anything else

23:58 <PovAddict> you can ship disks (or an entire NAS server) to Amazon and have them load the data into the S3 network

23:59 <zombie67> interesting, but even then, it has to transfer that over sas or ethernet or infiniband or something

23:59 <PovAddict> of course
