Ubuntu version of OpenCL

Polar01 · ‎04-22-2013

Hi,

Is there an installation package for Ubuntu ?

If not, it will be nice to have, a lot of customers would like to run my soft. on Ubuntu with the Intel SDK !

Thanks

Hi Polar01,

Download the Intel SDK for OpenCL Applications from Intel's web site (http://software.intel.com/en-us/articles/vcsource-tools-opencl-sdk/). After downloading, you will end with a .tgz file with an RPM inside (crazy, I know). In my case, the file is namedintel_sdk_for_ocl_applications_2012_x64.tgz.
Extract the RPM from the .tgz file:
$ tar zxvf intel_sdk_for_ocl_applications_2012_x64.tgz
This will extract the intel_ocl_sdk_2012_x64.rpm file.
Convert the RPM file to .deb format and install:
$ sudo apt-get install -y rpm alien libnuma1 # In case you don't have these packages $ fakeroot alien --to-deb intel_ocl_sdk_2012_x64.rpm $ sudo dpkg -i intel-ocl-sdk_2.0-31361_amd64.deb
Now the SDK and libraries will be installed to /usr/lib64, while Ubuntu expects them to be in /usr/lib. No problem, just make a symlink and update the library cache:
$ sudo ln -s /usr/lib64/libOpenCL.so /usr/lib/libOpenCL.so $ sudo ldconfig

That's all! OpenCL should be installed now.

Thx Ahmed ;-)

Yes, it sounds to be the way to do... but it is "complex" for basic users... I can do that but imagine that my customers are simple "artists" and they don't care about installing drivers etc... command line is a "geek" stuff for my customers :-D

I would like that Intel provide an "easy" way for theses peoples... it is important for basic users.

So, if someone of the Intel team can advice ?

But thanks for your help, Ahmed ;-)

Hello Arnon,

I have a Ubuntu 12.04 and from this link (http://software.intel.com/en-us/vcsource/tools/opencl) it looks like i should be using the Version XE 2013. The notes for this version say it has been tested on xeon processors. I do have a i5 with integrated Intel HD graphics on my machine. So which version should i install for this configuration (i5 with integrated graphics with ubuntu 12.04)? Please advise.

Thanks

Here are some steps I used with Ubuntu 13.04 and the new multi-package distribution Intel® SDK for OpenCL* Applications XE 2013:

Download the 64-bit distribution from Intel: intel_sdk_for_ocl_applications_2013_xe_sdk_3.0.67279_x64.tgz
Download the Intel public key. I had trouble finding it, but googling the filename pointed me to the correct page at Intel. Intel-E901-172E-EF96-900F-B8E1-4184-D7BE-0E73-F789-186F.pub

$ sudo apt-get install -y rpm alien libnuma1

$ sudo rpm --import Intel-E901-172E-EF96-900F-B8E1-4184-D7BE-0E73-F789-186F.pub

$ tar -xvf intel_sdk_for_ocl_applications_2013_xe_sdk_3.0.67279_x64.tgz
$ cd intel_sdk_for_ocl_applications_2013_xe_sdk_3.0.67279_x64/

$ fakeroot alien --to-deb opencl-1.2-base-3.0.67279-1.x86_64.rpm
$ fakeroot alien --to-deb opencl-1.2-intel-cpu-3.0.67279-1.x86_64.rpm

$ sudo dpkg -i opencl-1.2-base_3.0.67279-2_amd64.deb
$ sudo dpkg -i opencl-1.2-intel-cpu_3.0.67279-2_amd64.deb

The above installs the library files and intallable client driver registration in /opt/intel/opencl-1.2-3.0.67279.
Two more steps were needed to run an OpenCL program.

Add library to search path:
$ sudo touch /etc/ld.so.conf.d/intelOpenCL.conf
Edit this file, add the line:
/opt/intel/opencl-1.2-3.0.67279/lib64

Link to the intel icd file in the expected location:
$ sudo ln /opt/intel/opencl-1.2-3.0.67279/etc/intel64.icd /etc/OpenCL/vendors/intel64.icd
$ sudo ldconfig

At this point I could run an existing application. If doing developmnent, install the developer headers and tools:

$ fakeroot alien --to-deb opencl-1.2-devel-3.0.67279-1.x86_64.rpm
$ fakeroot alien --to-deb opencl-1.2-intel-devel-3.0.67279-1.x86_64.rpm

$ sudo dpkg -i opencl-1.2-devel_3.0.67279-2_amd64.deb
$ sudo dpkg -i opencl-1.2-intel-devel_3.0.67279-2_amd64.deb

It is worth noting the include path for headers is: /opt/intel/opencl-1.2-3.0.67279/include
The linking path for libraries is: /opt/intel/opencl-1.2-3.0.67279/lib64
The developer tool binaries are installed in: /opt/intel/opencl-1.2-3.0.67279/bin

Apologies for the probably-obvious question: on this page:

http://software.intel.com/en-us/vcsource/tools/opencl

It says OpenCL SDK is available for " Ubuntu* 12.04 (Host²) " - does that imply you can develop on that platform, but cannot execute?

Thanks -

Michael

Mitch_O_ · ‎06-08-2015

Is there an available OpenCL sdk somewhere at Intel. I've been playing around with the page where I keep getting sent, and all I can get is IDEs etc...

I'm running Ununtu 14.10 on an Intel Xeon(R) ES-2630

Thanks,

Mitch

Robert_I_Intel · ‎06-08-2015

Mitch,

You can download OpenCL runtime for Ubuntu here: https://software.intel.com/en-us/articles/opencl-drivers#ubuntu64

And Intel® Code Builder for OpenCL™ API 2015 for Ubuntu* (64-bit) here https://software.intel.com/en-us/articles/intel-code-builder-for-opencl-api .

That's about it.

Uri_L_Intel · ‎07-02-2015

Hello,

The OpenCL CPU runtime for Ubuntu OS comes with Intel OpenCL Code Builder for Ubuntu package (https://software.intel.com/en-us/articles/opencl-drivers#ubuntu64)

The version you're trying to install is supported on SLES and RHEL operating systems only.

We'll modify the release notes to better clarify it.

Thanks,

Uri

Zeshan_A_ · ‎07-06-2015

Hallo Uri,

Thank you for response,

i tried to install your given link "Intel OpenCL Code Builder for Ubuntu package (https://software.intel.com/en-us/articles/opencl-drivers#ubuntu64)" , but still give the message in installing Mode " Unsupported Operating System, Does Intel Code builder for ubuntu support only 12.04 LTE OS.

i am try to install on 14.04.1-Ubuntu (64 bit) .

1) extract the tar IntelOpenCL SDK.

2) run the install_GUI .

("Message : Unsupported OS Version ")

What should i do , should i change my ubuntu version or have intel any solution for compatibility with new version of ubuntu (14.04.1-Ubuntu (64 bit) ).

it will be the great help for me ,if you advise me to install the intelOpenCL SDK steps on my system.

Best Regards,

Zeshan

The following steps worked for me on Ubuntu 15.04 based on Noah's instructions above: $ sudo apt-get install -y rpm alien libnuma1 $ tar -xvf intel_code_builder_for_opencl_2015_ubuntu_5.0.0.43_x64.tgz $ cd intel_code_builder_for_opencl_2015_ubuntu_5.0.0.43_x64 $ sudo rpm --import PUBLIC_KEY.PUB $ cd rpm $ fakeroot alien --to-deb opencl-1.2-base-5.0.0.43-1.x86_64.rpm $ fakeroot alien --to-deb opencl-1.2-intel-cpu-5.0.0.43-1.x86_64.rpm $ sudo dpkg -i opencl-1.2-base_5.0.0.43-2_amd64.deb $ sudo dpkg -i opencl-1.2-intel-cpu_5.0.0.43-2_amd64.deb The above installs the library files and installable client driver registration in /opt/intel/opencl-1.2-5.0.0.43.

I definitely have problems with the newest version intel_sdk_for_opencl_2016_ubuntu_6.0.0.1049_x64.
it seems that when it comes to "Link to the intel icd file in the expected location:" there is no file /opet/intel/opencl*/etc/*icd to link.

jaky@jaky-Satellite-S55-A:/opt/intel$ ls

Is there any detailed guide for this specific version to follow?
Is there a way to clean the installation to start from the scratch?
Thank you in advance.

Hi,

I am also facing the same problem as Jacopo. I cannot find icd files and also in rpm folder I cannot find opencl-1.2-intel-cpu-*.rpm. Can anyone help me how to solve this problem?

Regards,

Nishma Laitonjam

Robert_I_Intel · ‎04-27-2016

Hi Nishma,

You will have to install a CPU runtime for Ubuntu separately: https://software.intel.com/en-us/articles/opencl-drivers#16.1ubuntu64 .

I installed GPU runtime that came with the SDK first, then installed the CPU runtime above, then set LD_LIBRARY_PATH to point to the location of CPU OpenCL runtime dlls, and then I can see both CPU and GPU devices.

nishma_l_ · ‎04-28-2016

Hi Robert,

Thanks for your help, now I can find .icd file. But when I run (sudo clinfo), I got the following error :-
modprobe: ERROR: could not insert 'fglrx': No such device
Error! Fail to load fglrx kernel module! Maybe you can switch to root user to load kernel module directly
modprobe: ERROR: could not insert 'fglrx': No such device
Error! Fail to load fglrx kernel module! Maybe you can switch to root user to load kernel module directly
modprobe: ERROR: could not insert 'fglrx': No such device
Error! Fail to load fglrx kernel module! Maybe you can switch to root user to load kernel module directly

I am very grateful, if you can help me with this also. Thank you for your time.

Nishma Laitonjam

Robert_I_Intel · ‎04-28-2016

Hi Nishma,

I was unable to run clinfo either: different error though. Try to get Intel samples for Linux https://software.intel.com/en-us/intel-opencl-support/code-samples and build the CapsBasic one. You can also try to get it here: https://software.intel.com/en-us/articles/caps-basic - build it and run it and let me know if that worked for you. Make sure to add /opt/intel/OpenCL-1.2-5.2.0.10002/lib64 to your LD_LIBRARY_PATH.

Let me know how it goes.

nishma_l_ · ‎04-28-2016

Hi Robert,

When I run ./capsbasic, I get the following message

Robert_I_Intel · ‎04-28-2016

Hi Nishma,

1. Could you run any other of the Intel samples? Do they run on the CPU device, and you just get the error messages in the output, as above?

2. Looks like fglrx is giving you trouble (https://en.wikipedia.org/wiki/AMD_Radeon_Software_Crimson#Linux ), but the Intel CPU driver is actually doing its thing. Somehow AMD driver does not play well with our driver or vice versa.

I have no way to replicate your hardware configurations. One thing you could try is to make sure that LD_LIBRARY_PATH, in addition to pointing to Intel OpenCL libraries, points to AMD ones as well. Check this out too https://elrepo.org/bugs/view.php?id=457
