22) Questions and Answers : GPU applications : v7 vs Enhanced vs Astropulse (Message 1539822)
Posted 13 days ago by Profile Ageless
There are only two types of tasks these days: astropulse and multibeam Seti v7.
The Seti Enhanced v6 is what was before Seti v7. Before Seti Enhanced you had Seti Classic 2, 3 and 4, before it went to Seti@Home 5.28, which was superseded by Seti Enhanced v6, which has now been superseded by Seti@Home v7.

Each of the following science application can do more with the data, look deeper into it, see better through radar blanked areas etcetera. This is also why it can happen that older data is being looked back at, because the science application can do better than its predecessor.

For the specific FAQs on what the two look for:

You could of course, get a Linux that has BOINC available from repository, so it's built against the libraries in that Linux distribution and therefore more likely to work out of the box.
See http://boinc.berkeley.edu/wiki/Installing_BOINC#Linux

There is really no need to constantly trying to reinvent the wheel. BOINC has been here for quite some time already (since 2002) and is quite wide-spread. Lots of people try to port it to make it work on their operating systems.

(Apropos, learn once, repeat forever. It's BOINC: Berkeley Open Infrastructure for Network Computing)

I created this file using notepad, put it in the correct directory but it doesn't work.

<?xml version='1.0' encoding='us-ascii'?>

You used the wrong encoding. When using Notepad to make the file, use ANSI encoding, the default it comes with. Anything else is unnecessary.

And when you say "correct directory", what may that be?

What speed internet do you have? As I see you got at least one Astropulse, and those at 8MB can interfere with downloading of other stuff/general surfing on slower connections. Just consider that when you want that one to come in in one second, that you need at least a 64Mbit connection.

28) Questions and Answers : GPU applications : AMD A-10 7850K. (Message 1536489)
Posted 19 days ago by Profile Ageless
If I just understood you right, we can run stock Bonic/Seti on this cpu/gpu and will get gpu related work?

As long as BOINC recognizes the GPU and sees it as a CAL capable device, then yes. If it doesn't see it as a CAL capable device, well, bets are off at the moment. Seti uses the CAL detection at the moment to decide if an AMD/ATI GPU can run OpenCL or not. That may be weird, but the admin is working on that.

Here is why I am interested: "...the new Kaveri chips should offer a total compute power of 856 gigaflops when you combine its up-to 12 compute cores (4 CPU cores and up-to 8 Radeon R7 GPU cores)..

OpenCL is only available at Seti for GPUs, not for CPUs (yet). So the CPU cores would get 'normal' Seti v7 applications to run. The GPU would get an OpenCL application, or more than one. Depends on how we need to read that.

Compute Cores aren't synonymous to GPUs. So it's not that the GPU has 8 GPUs. It's one GPU with 8 compute cores. Which can run one OpenCL task, but across those 8 cores simultaneously.

Is there a better way to restart boinc that is safe.

See the BOINC FAQs: How to exit BOINC completely?
Then after that you just restart BOINC by going Start->(All) Programs->BOINC->BOINC Manager.

What about the completion times on the gpu units. Do they vary greatly? Thanks.

The length of run time depends on the angle at which the tasks were recorded against the night sky. The lower the angle range, the slower the task will run. The higher the angle range, the faster the task will process.

Next time check the CPU temperature. Some of these tasks fall back to running on the CPU when the GPU can't handle them.

There is still an OpenCL_ATI5_NoCAL app, perhaps that your system picks that one up.


Where?

Available by automated download when using the default science applications and an AMD/ATI GPU that doesn't any longer support CAL by hardware.

I am interested in the AMD A-10 7850K. Not this week or this month but maybe in the longer term. It LOOKS like it should be able to run a "ton" of Seti gpu tasks with 8 gpus. But since it apparently doesn't have CUDA support is there a way around that?

CUDA is the proprietary GPGPU calculation method used only by Nvidia GPUs. It stands for Compute Unified Device Architecture.

CAL was the proprietary GPGPU calculation method used by ATI GPUs. It stood for Compute Abstraction Layer.

OpenCL is what is now the open source newest format when it comes to GPGPU calculations. It stands for Open (source) Computation Language and can be used on GPUs, CPUs and a couple of other processing devices as well. It's a one language - multiple uses resource language.

Whereas ATI (now AMD) has stopped developing CAL in favor for OpenCL, Nvidia has done it the other way around and stopped OpenCL development and support for their GPUs and is only gearing towards their own CUDA.

This means that all present Nvidia GPUs can do OpenCL 1.0 or 1.1 and won't have support for the newer versions. They can run newer OpenCL, but won't use the new functions of OpenCL. A bit like being able to run DirectX 9c on a DirectX 7 videocard. It'll use the Dx7 functions in Dx9c, but not all the shiny new things that Dx9c could do. No hardware support.

Thus, the AMD A-10 7850K APU has full OpenCL support, and will be able to run 4 CPU tasks and 8 OpenCL GPU tasks.

Do you need my first 30 lines of my log too?

No, I'm asking for the partial stderr.txt in the hopes that someone who can read those things can glance at them and see where things go wrong. But that's probably something that isn't in the log.

Have you ever tried to continue to run such a task?
Have you tried to fully exit BOINC & restart it?

my app_info.xml file.

The file referred to in this thread is the application configuration file, its name shortened to app_config.xml
With this file you can configure how many tasks BOINC should schedule to run on an appointed application and GPU. This file can be used with the default project provided science applications, and the third party science applications used through the anonymous platform module.

-- -- -- -- --

The application information file (app_info.xml) is used by anonymous platform applications, and is used so the user can dictate to BOINC what application it should run instead of the default science application provided by the project. This way you can use apps that are optimized specifically for your CPU/GPU, or that you compiled yourself.

-- -- -- -- --

The two aren't synonyms of each other. You can use an app_info.xml file at all times, with or without an additional app_config.xml file. Many of the things you can do in the app_config.xml file, you can do in the app_info.xml file. But for fine tuning the scheduling process, it's best to use the app_config.xml file.

Posted 19 days ago by Profile Ageless
For "gpu type" I think you are referring to cc_config.xml and in app_config.xml is the "coproc"?

Perhaps that the question setting makes sense for you, but it doesn't for me. So could you please elaborate? As far as I know, I didn't refer to gpu_type anywhere.

As I have written elsewhere in answer to you as well, since you continue to say app_info.xml where you mean app_config.xml:

Posted 20 days ago by Profile Ageless
It lacks well filled out examples. And it doesn't answer the question of:

app_info.xml (you mean app_config.xml - Jord) -> in the Seti at home project directory

The Application configuration section starts with:
This mechanism allows you to specify scheduling parameters for specific applications or app versions. It is available with 7.0.40+ client versions.

To do this, create a file app_config.xml in the project's directory, e.g. when the project is SETI@home: {BOINC Data directory}\projects\setiathome.berkeley.edu\


How does gpu_usage interact with cpu_usage? Why does it cause (usually) 2 tasks on each of two gpus?

One has to keep in mind that the main developer (and boss, owner etc.) of BOINC (not Bionic, certainly not Bionnic unless you know what that acronym stands for?) goes through the User Wiki and weeds out what he finds superfluous and useless information on a regular basis. So even when I today put in the information into that Wiki, I cannot guarantee that it will stay there. It may be gone by day-break tomorrow.

app_info.xml is a whole different kettle of fish. It is used by anonymous platform applications - which are non-default by project delivered, non-downloaded automatically by BOINC applications - and is described in http://boinc.berkeley.edu/wiki/Anonymous_platform. Please do not confuse the one with the other. Although both, since they work on a per-project basis, run from the project directory.

Posted 20 days ago by Profile Ageless
That line was only added to the Computer page last March [1], and the wording seems slightly misleading. It's actually a measure of how much GPU work has been done recently, not whether it has been allowed.

It is of course 0.00% for a host like my Pentium-M laptop which doesn't have a usable GPU. It would also be 0.00% for any project which doesn't have a GPU app version for the particular GPU and installed drivers. I'll assume such factors aren't involved for your case, though would rather not have to guess due to hidden computers.

I only run Seti & Einstein work on my GPU, yet my line says 0.00%
So clearly broken. :)

Edit: Apropos, my client_state.xml file, where that info should be coming from, says <gpu_active_frac>0.563743</gpu_active_frac> on a <active_frac>0.591852</active_frac> on a total <on_frac>0.162661</on_frac> :)

Edit2: Answer back from development:

37) Questions and Answers : GPU applications : ATI GPU requirements? (Message 1536319)
Posted 20 days ago by Profile Ageless
Sorry to say, but the NoCAL application has been retracted for the moment due to it giving problems on the systems of people with older videocards. Getting a driver restart (with required BOINC and/or system restart) every time that the app loads isn't something you want to go through. There is still an OpenCL_ATI5_NoCAL app, perhaps that your system picks that one up.

Posted 20 days ago by Profile Ageless
Okay, the 'normal' Seti v7 OpenCL applications work fine on AMD cards. I certainly don't have a problem with them. But the one NoCAL application seemed to be causing all this trouble for you and the original poster (and probably a lot more people). Until the administrator can find out what's causing this, he has retracted the NoCAL application.

39) Questions and Answers : GPU applications : getting an ATI Radeon HD 3400 to work (Message 1536316)
Posted 20 days ago by Profile Ageless
The 3400 doesn't support OpenCL, so the only thing you can run on it is CAL/Brook+
That was ATI's version of GPGPU before they fully embraced OpenCL.

http://setiathome.berkeley.edu/apps.php will show you that the only CAL capable application is one for Astropulse. However, your GPU doesn't have enough memory to run that. Minimum requirement on AP is I think 512miB.

You had to quote his whole post to then break his app_info.xml file? Ofcourse the end </app> needs to be there. There was one <app> at the beginning of that section.

@OP, how did you write and save the app_info.xml file? Notepad, format ANSI?
