21) Questions and Answers : GPU applications : Radeon and Nvidia at the same time? (Message 1791688)
Posted 29 May 2016 by Profile Ageless
Usually it's possible, but you have to install the drivers in a specific order, if I am not mistaken Nvidia first, AMD/ATI last.

You'll also have to read the motherboard manual on how to enable both the onboard graphics and the external graphics card, as inserting a card may disable the onboard graphics.

If you don't add a monitor to both video-outlets, it's possible one of the graphics cards doesn't work. You may need to add a dummy VGA in order for both cards to be recognized. It doesn't always suffice to extend the desktop over two videocards.

When the two graphics cards are of differing brand or differing strength, BOINC will only use the best by default. You'll have to add a cc_config.xml file with at least these lines:
<cc_config> <log_flags> </log_flags> <options> <use_all_pus>1</use_all_gpus> </options> </cc_config>

This is saved in the BOINC data directory.

From first looks it would seem your videocard drivers have gone missing, or they were updated but now lack the OpenCL component that's required to do work here. Only your CPU is being recognized as OpenCL capable.

Maybe the diversity of hardware requires more apps than some would realize.

Hardware is hardware is hardware. There's a big difference in hardware between a Pentium 4 CPU, an early AMD Athlon and the newest Intels and AMDs. Yet they all run one and the same v8 application. There isn't even a 64bit version of the application, just one plain 32bit version.

As long as it all works, this is a rather stupid question in the first place.

Double-check whether all of the applications you are referring to by plan_class names are actually different binary executables. I think they probably are, this time round, but it's as well to be sure. In earlier incarnations, sometimes the same app appeared in different clothes - e.g. so that an OpenCL app could present and be run as a straight ATI/CAL app for the benefit of a pre-OpenCL client.

Let's see...
SAH is not used on APUs.
CAT132 is not used on APUs.
NOCAL is not used on APUs (although this is strange, it includes _ATI_, but as far as I know there are no pre-ATI5 GPUs that don't have CAL support.)
SOG is not used on _ATI_

According to the Applications page we have the choice of: opencl_ati5_cat132, opencl_ati5_nocal, opencl_ati5_sah, opencl_ati5_SoG, opencl_ati5_SoG_cat132, opencl_ati5_SoG_nocal, opencl_atiapu_sah, opencl_atiapu_SoG, opencl_ati_cat132, opencl_ati_nocal, opencl_ati_sah
Thus far I have seen:
setiathome_8.12_windows_intelx86__opencl_ati_sah.exe
setiathome_8.12_windows_intelx86__opencl_ati5_sah.exe
setiathome_8.12_windows_intelx86__opencl_ati5_SoG.exe
setiathome_8.12_windows_intelx86__opencl_atiapu_sah.exe
setiathome_8.12_windows_intelx86__opencl_atiapu_SoG.exe

What I see is that opencl_ati5_cat132 is run with setiathome_8.12_windows_intelx86__opencl_ati5_sah.exe and opencl_ati5_SoG_cat132 with setiathome_8.12_windows_intelx86__opencl_ati5_SoG.exe

I think that the best current answer is more along the lines of "no-one can predict which application will perform best on a given host, given the variety of hardware platforms (GPU + host CPU/motherboard) run by volunteers here - which greatly exceeds the number of platforms run by testers". So Eric lets BOINC work it out by itself.

Then how does a project like Primegrid manage to run 24 different kinds of prime calculations with all just one application per sort of hardware? They must be aces in being able to predict how their applications work on the variety of different sorts of hardware. Or maybe they're just not thinking too difficult about it, and just have the one application fits all methodology. :)

In that sense it really doesn't matter what the science is that's being done, whether it's to find the first tooth paste commercial of the aliens nearest to us, or to find a prime with more than 1,024,921 digits.

P.S. and regarding your funny ignorance about what SoG means... use the search they say? ;)

Oh, I know what it means, but since it must be a direct translation from something in Russian, it doesn't make any sense in English. You should've called it "Stargazing one's Gaussians" instead of "Signals on GPU", to stay in the spirit of Seti@Home.

Strange you did not asked that question on 5 CUDA apps introduction

Why is that strange? I don't have an Nvidia GPU. Had you taken the time to read my post(s) you would've seen I have removed the anonymous platform file, reset the project and am now running some stock work on my AMD HD7870 only.

there is some difference in app that each suits different hardware better

OpenCL applications run on any OpenCL capable piece of hardware, as long as there are drivers for it and it's recognized as OpenCL capable. Essentially, an OpenCL application for an Nvidia GPU should be able to run on an AMD GPU, on a multi-core CPU, on any non-GPU co-processor and anything else that's OpenCL capable. Or as the Wikipedia page about it says: "Open Computing Language (OpenCL) is a framework for writing programs that execute across heterogeneous platforms consisting of central processing units (CPUs), graphics processing units (GPUs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs) and other processors or hardware accelerators. OpenCL specifies a programming language (based on C99) for programming these devices and application programming interfaces (APIs) to control the platform and execute programs on the compute devices. OpenCL provides a standard interface for parallel computing using task-based and data-based parallelism."

I hope you know what heterogeneous means.

If you so much want to suit all the different hardware better, then do so through the Lunatics optimized applications range, but leave it out of the stock applications.

Answering in small bits, so Raistmer doesn't have to read big posts.

30) Questions and Answers : Windows : boinc manager won't communicate (Message 1790938)
Posted 27 May 2016 by Profile Ageless
1. You did not allow boinc.exe and boincmgr.exe through your firewall. These two parts of BOINC need to be able to talk to each other on TCP port 31416. Usually putting boinc.exe and boincmgr.exe in your firewall's trusted zone fixes this. Just restart BOINC afterwards.

2. The client was stopped for whatever reason and only BOINC Manager was kept running. Exit BOINC Manager and restart it to see if this fixes your problem.

3. Another program has taken up port 31416. In this case you will have to figure out which program does this and exit it, then make sure that BOINC starts earlier than the other program.

4. You had a GPU of some brand in your PC, have since removed it, but didn't uninstall and clean out its drivers. Best do so, to get BOINC to work with you.

Great, I put the question down, get 5 reactions of which 3 are a straight non-answer -including a snigger from the developer of these applications- one is someone with a moment of clarity and the other one is starting to give an explanation to then go off on a tangent about power users.

The question is simple: why is there a need for 5 (or 7) different applications on the same hardware resource? It's not just for my understanding, but also for total newbies, or people who do read here - and wonder about the same thing - but have till thus far been too afraid to ask, perhaps due to exactly this circumstance: you ask a question and get non-answers. Or you get totally unnecessary advice about running an optimized application, with no explanation on how to do that, or what to do when a new version of the Seti applications comes out. After which you have a 95% chance that your thread ends up in a pro and con fight over the use of power apps, credits, and which GPU brand is best.

So back to the problem at hand. An analogy:
You go to 7 different stores to do your shopping and instead of using just one bank-card between them to pay for everything, all stores prefer their own payment method and so you walk around with a minimum of 5 cards, a load of cache and a pile of coupons. Yes, not impossible, but completely insane.
Similarly, I don't see why one guppi needs to be done with the opencl_atiapu_sah app, then the next guppi with the opencl_ati5_sah app, then six MBs with the opencl_atiapu_sog app, one MB with the opencl_atiapu_sog_sah app, and two further MBs with the opencl_ati_sah app. I have an external HD7870 GPU, it's not an APU so I don't really need the ATIAPU apps. It's not a HD4xxx card, so I don't really need the *_ATI_* apps.

If this is due to that Seti doesn't strictly follow the plan_classes...
If this is due to Seti not being able to recognize the correct hardware versus the correct plan_class...
If this is due to there being no filter for specific GPU names per plan_class...
If this is due to the wide variety in hardware being available and the application not being able to switch internally to an older or newer OpenCL version, then say that.
(ever thought about adding a check in the app to see what OpenCL capability there is and switch internally to the right app? It means a bigger science application, but imo simpler, because you don't see the switching, and you don't have 5, 7 or 11 different application names to switch between.)

Now,
I understand that we need a SAH application (cat132) for the older HD46xx/48xx hardware.
I understand we need the ATI5 application to diverge from the above. But then ATI5 applications should be sent to minimum HD5xxx GPUs - which they aren't.
I understand we need the NOCAL application for the newer hardware that doesn't do CAL recognition anymore, a thing required by BOINC and most science applications (here and elsewhere) to be able to recognize that this is indeed an ATI GPU and something capable of OpenCL.

It would be nice if the above would follow the plan_class they were made for, but I have seen ATI5 apps being sent to HD4xxx GPUs and then erring.

The Sneezing on Grass (SoG) application versions, mwoh thus far I don't see the need for it. It's not running work faster than the ATIAPU, ATI, ATI5 or SAH/CAT132 applications, on guppi's it's more likely slower. The warmest my GPU gets is with the Stepping on Glass (SoG) applications, the coolest it stays with the various SAHs. A difference of as much as 10 degrees centigrade (71C with a fan speed of 70% (3,000rpm) versus 61C with a fan speed of 40% (1,740rpm)), so I prefer to run the lower apps over the Sniffing on Glue (SoG) apps anytime.

Here's a thought to clamp onto: there is talk about adding BOINC to the Apple Store, but Apple then requires that the BOINC Installer includes all possible science applications for all projects, because it does not allow applications in its store that download other applications. If the developers set this through, they wouldn't want to have to include 11 different stock Seti applications for the Mac only because there is a possibility that people run older hardware. They'd want one, maybe two applications per project's science range. Because with 50+ projects, you don't want people to download 750MB of installer including 60 applications per project.

Since tonight I run stock Seti applications on my AMD HD7870, Windows 7 x64, Crimson 15.12 drivers.
Where BOINC for the first 6 tasks downloaded the v8.12 OpenCL ATIAPU SoG (opencl_atiapu_SoG) application, it's since gone and downloaded also the OpenCL ATI SAH (opencl_ati_cat132), OpenCL ATI5 SAH (opencl_ati5_cat132), OpenCL ATI5 SoG (opencl_ati5_SoG_cat132) and OpenCL ATIAPU SAH (opencl_atiapu_sah) applications. I don't really see the need why it should do so. It's running just normal MBs and Guppi VLARs, I guess just like everyone else.

The downside of this is of course that it now takes at least 5 times as long before my computer is being seen as trustworthy, because it now needs to do 5 times the '10 task minimum without error' validation rounds.

Seeing the applications page, there's probably two more applications I see that can be sent my way.

You haven't run enough work units to really tell what's going on.

Point of attention, I was trying to help, not running the work. I don't have a Mac. :)

35) Questions and Answers : GPU applications : Is my GPU too old for numer crunching? (Message 1789995)
Posted 24 May 2016 by Profile Ageless
Even the oldest Nvidia GPUs should still be able to get work, and do it albeit slowly. But since you have your computer hidden, you'll have to give the rest of the details on it:
- Operating system
- since you seem to have a laptop or notebook, what specific brand is it?
- where did you get the videocard driver from?
- Have you tried updating it from the Nvidia site? Or do you get an error then because of the proprietary brand laptop/notebook?

OK, I'll try to get the Mac developer of the Seti v8 application to come and look.

Do you know what driver you use for the AMD GPU?
Did you install it yourself from the AMD site, or is it included in your OS X?
Which OS X is this?

Did any of those tasks finish normally or in error? Or do they validate correctly?
Can you link to a result file? You have your computer(s) hidden so I cannot check whether you have errors or not.

Have you followed its advice, and rebooted?

When you have various tasks with dubious outcome, it's possible that something in the computer is wrong which could be corrected with a reboot. Think about a bit wrong in memory, or something stuck on the hard drive.

Posted 20 May 2016 by Profile Ageless
Ah, do know that the normal file size of the logs will only be 2MB, before they roll over to an *.old format. The next roll-over removes the first *.old and gets overwritten with the contents of the present log.

This is true for all log files, but in majority for the stdoutdae.txt and stderrdae.txt files.

Best chat with everyone else on that subject in https://setiathome.berkeley.edu/forum_thread.php?id=79418. Or read through that thread. Lots of info in it.
