OpenCL

reverendjim · ‎04-15-2018

Is there a version of OpenCL that works with the AMD Radeon R5 M335? My system is a Dell Inspiron 5759 running Windows 10 Home. My development environment is Microsoft Visual Studio 2012 but I can install whate er else is required.

elstaci · ‎04-16-2018

Here is AMD OPENCL FORUM :OpenCL .

Someone there should be able to answer your question.

reverendjim · ‎04-16-2018

I'd ask my question there but there doesn't seem to be any way to ask a question, only read what has already been posted.

Ray_AMD · ‎04-16-2018

I've moved your question to the OpenCL forums.

elstaci · ‎04-16-2018

I was able to locate on the Opencl Forum where you can post any future questions.

It is on the Upper Right Corner under "Actions" then "Create" and then "Discussion" . Pops up a window to ask your question. Future reference.

Please try this driver: Mobile

reverendjim · ‎04-16-2018

There are three downloads on that page. How am I to know which is the correct one? Also, is there any FAQ or document that describes how to set up a dev environment? A driver is the first step, but it is certainly not all that is required. I'd rather not have to install/uninstall (rinse/repeat) until I finally end up with what I want.

dipak · ‎04-16-2018

Adrenalin 18.2.1 and 18.3.4 both the drivers support this card. Adrenalin 18.3.4 is the latest one.

After driver installation, please install AMD APP SDK which provides the headers and libraries required to develop OpenCL application on AMD platform.

Note:

If you face any issue to download the installers, please try this link:

64-bit: http://amd-dev.wpengine.netdna-cdn.com/app-sdk/installers/APPSDKInstaller/3.0.130.135-GA/full/AMD-AP...

reverendjim · ‎04-16-2018

Great. I'll grab those files and start in on it. Thanks very much for the help.

Still a few bumps in the road.

Windows 10 (Home) Dell Inspiron 5759

Visual Studio 2017 (Community Edition)

When I try to build from Conway.cpp, whether I select Win32 or x64 as the platform in project properties I get the following error.

LNK1112 module machine type 'x64' conflicts with target machine type 'x86' afopencl.lib(afopencl.dll)

When I try to run the included benchmark blas_opencl.exe I just get

blas_opencl.exe - System Error

The code execution cannot proceed because afopencl.dll was not found. Reinstalling the program may fix this problem.

What, specifically, am I being asked to reinstall?

It seems more than a bit of a nuisance to have to

o Add "$(AF_PATH)/include;" to Project Properties -> C/C++ -> General -> Additional Include Directories.

o Add "$(AF_PATH)/lib;" to Project Properties -> Linker -> General -> Additional Library Directories.

o Add afopencl.lib to Project Properties -> Linker -> Input -> Additional Dependencies.

to every new project. Surely there is some way to add them in to Visual Studio so that they can be included in all new projects. Although I see you also state "You can alternately download the template project from ArrayFire Template Projects". What do I have to download and where am I supposed to put it/them?

After installing the driver and APPSDK, please try the below steps to ensure that the setup is ready for OpenCL development:

Run "clinfo" from the command-line and check the output. Clinfo output should list the CPU and GPU devices.
If clinfo is running fine, try to run couple of OpenCL sample binaries (typically located at <Users>\AMD APP SDK\3.0\samples\opencl\bin\x86_64) to confirm that OpenCL is working fine on the target device. On the other hand, if clinfo fails to recognize any device, then there might be an installation issue or the device is not supported by the driver. Retry the installation process.
Now, try to build an OpenCL application from source. For this purpose, provided VS projects against APPSDK OpenCL samples can be used (located at <Users>AMD APP SDK\3.0\samples\opencl). If the samples are building and running fine, then the setup is ready for OpenCL development. Note, depending on the target OS, please select the build version (x64 or x86).

Please check this documents for more information.

I tried to rebuild KmeansAutoClustering from the samples folder. First

of all, I noticed that the settings:

C/C++ Additional include directories:

../../../../../include

../../../../../include/SDKUtil

$(AMDAPPSDKROOT)/include

Linker additional library directives:

../../../../../lib/win64/

differed from the recommended setting on the website which were

Add "$(AF_PATH)/include;" to Project Properties -> C/C++ -> General ->

Additional Include Directories.

Add "$(AF_PATH)/lib;" to Project Properties -> Linker -> General ->

Additional Library Directories.

Add afcpu.lib or afcuda.lib or afopencl.lib to Project Properties ->

Linker -> Input -> Additional Dependencies. based on your preferred backend.

Also, when I tried the rebuild I got 320 errors. Clearly somethijng is

amiss.

Most execs of prebuild exe files run without error - here is one exception:

The AMDAPPSDKROOT variable must be set to:

C:\Program Files\AMD APP SDK\ (for 32-bit systems)

C:\Program Files (x86)\AMD APP SDK\ (for 64-bit systems)

This seems to be backwards. Surely it should be

C:\Program Files\AMD APP SDK\ (for 64-bit systems)

C:\Program Files (x86)\AMD APP SDK\ (for 32-bit systems)

The AMDAPPSDKROOT variable must be set to:...This seems to be backwards. Surely it should be...

AMDAPPSDKROOT environmental variable points to the location where CPU runtime and other developer components are placed. On Windows 64bit OS, by default, the location is: C:\Program Files (x86)\AMD APP SDK\ . So, the setting mentioned in the installation guide seems correct to me.

differed from the recommended setting on the website which were...

I guess, you are comparing APPSDK project setting with ArrayFire. These two are different projects and their dependencies (headers and libraries) are different. Each setting is valid for its own project.

Most execs of prebuild exe files run without error - here is one exception:

The error reported by SimpleDepthImage sample is expected one. OpenCL 2.0 samples won't work on that gpu device as it does not support OpenCL 2.0.

when I tried the rebuild I got 320 errors. Clearly somethijng is amiss.

Normally you get so many errors when there is something wrong in the project setting. That's what I'm suspecting too.

Btw, did you get this error against APPSDK sample or arrayfire sample? If for APPSDK sample, please share the build errors.

reverendjim · ‎04-24-2018

On Windows 64 bit systems, 64 bit apps are installed, be default, in

C:\Program Files. Older, 32 bit apps are installed in C:\Program Files

(x86) so the settings in the documentation, if not a typo, are grossly

misleading (see here

<https://www.howtogeek.com/129178/why-does-64-bit-windows-need-a-separate-program-files-x86-folder/>).

The large number of errors are when I try to build the AMD SDK sample in

OpenCL1.xSamplesVS10.sln - KmeansAutoClustering. I can't copy/paste the

errors because, unlike some earlier versions of Visual Studio, each

error must be copied/pasted individually. However, I have attached a few

screencaps showing some of the errors.

The reason I am doing this in the first place is because my older son

has just started a research position in Cambridge (computational

biophysics) and will be setting up a GPU computer system. His will be

using CUDA, but after reading about CUDA and ArrayFire I concluded that

the benefit of the abstraction provided by ArrayFire would greatly ease

his programming. It would also (in theory) allow him to write code that

would be more easily ported to AMD/Radeon systems. I'm starting to

wonder if the difficulty in getting an ArrayFire development system set

up is worth the ease in programming with it.

On Windows 64 bit systems, 64 bit apps are installed, be default, in C:\Program Files. Older, 32 bit apps are installed in C:\Program Files(x86) so the settings in the documentation, if not a typo, are grossly misleading..

I understand what you are trying to point. However, I think there is some confusion in this regard. Just to clarify my earlier statements. On Windows 64bit OS, C:\Program Files (x86)\AMD APP SDK\<VERSION> is the location where the installer places the CPU runtime and other developer components. By default, AMDAPPSDKROOT environmental variable points to this base directory.

Inside that base directory, two versions of libraries and executables can be found under two different sub-folders namely "x86" and "x86_64" for 32-bit and 64-bit applications respectively. Based on the target build, an OpenCL application should set the link path accordingly. For example, for 64bit application, "OpenCL.lib" should be linked against the path "$(AMDAPPSDKROOT)\lib\x86_64" [assuming AMDAPPSDKROOT variable is set to APPSDK base directory i.e. C:\Program Files (x86)\AMD APP SDK\<VERSION>].

I have attached a few screencaps showing some of the errors.

From the attached snapshots, it looks like a project setting issue because the program was unable to include the required header files (APPSDK and OpenCL).

I decided to forego testing AMD SDK examples and just try

loading/building an arrayfire example (conway_pretty_vs_2013. This one

worked so I'll play around with things for a while.

Clearly I am missing something. The getting started guide says

The ArrayFire API is wrapped into a unified C/C++ header. To use the

library simply include the arrayfire.h header file and start coding!

But even that doesn't work. Just typing #include <arrayfire.h> fails

(not found). I started a new windows c++ console project. I made sure

the properties entries matched those in the conway pretty project. When

the IDE failed to find arrayfire.h I checked the corresponding External

Dependencies. The conway project had all the arrayfire header files. The

new project did not. I'll assume I am missing a step but I have no idea

what it is.

By now you are sick of hearing from me.

I'm having a really bad day. I noticed my new project was set to x86.

When I switched to x64 arrayfire.h was then recognized. Please ignore

the previous rants.

LoL, I have no idea what you are doing, but that last post pretty well describes must Users when they get frustrated.

I got hung on a problem with Visual Studio 2017. I set up the basic

environment with default code and the proper includes/libs etc/, then

exported the template. However, creating a new project based on the

template just results in

when I try to open the default code of

// ArrayFire1.cpp : Defines the entry point for the console application.*

**// 2018-04-24 15:41 **

**

*#include <arrayfire.h>*

*#include <iostream>*

*#include <cstdio>*

**

*using namespace af;*

**

*int main()*

*{*

** return 0;**

*}

After googling that error I found many other users with the same

problem. Microsoft's response to date has been pretty much "Your call is

important to us. Please stay on the line...". More accurately it would

be "We are prioritizing the issues and looking into them".

So I zipped the prototype project so I could recover it and decided to

use it to copy in the benchmarks/blas.cpp code from the arrayfire

website <http://arrayfire.org/docs/benchmarks_2blas_8cpp-example.htm>

#include peak)

peak = gflops;

printf(" %4.0f Gflops\n", gflops);

fflush(stdout);

}

catch (af::exception& e) {

fprintf(stderr, "%s\n", e.what());

throw;

}

printf(" ### peak %g GFLOPS\n", peak);

return 0;

}

Building that gives me

Arrayfire has its own place to report/discuss the issues. For Arrayfire related issue, I would suggest you to check their support community for better and quicker response.

Btw, MS says this about Error C1010: Fatal Error C1010 | Microsoft Docs

Thank you very much for your incredible patience and help in getting my

environment set up. I now have a prototype app with all of the custom

stuff defined. I can copy in the sample ArrayFire code and compile/run.

The last hurdle will be to take the prototype and create a template.

That is certainly not a problem that would concern you. That will

require some more research/reading on my part as I familiarize myself

with Visual Studio 2017 (Microsoft loves to keep changing where things

are and how to do things). Once I have everything documented I plan to

post the entire process from download to config on Daniweb

<https://www.daniweb.com/> so that others there can hopefully benefit

from what I have learned.

Thanks again,
