Intel Media Server 2015 SDK for Linux (OpenCL)

[Zeshan_A_]

Hi All,

 our company interested to use the "Intel OpenCL SDK " for performance . I download the the  Intel® Media Server Studio 2015 –Driver, SDK for Linux* and install on my system.

My system specification: Intel i7 Core processor with built-in Intel HD graphics card. operating system Ubuntu 12.04 x86_64 bit.

lshw -c video -> Beschreibung: VGA compatible controller
       Produkt: 3rd Gen Core processor Graphics Controller
       Hersteller: Intel Corporation
       Physische ID: 2
       Bus-Informationen: pci@0000:00:02.0
       Version: 09
       Breite: 64 bits
       Takt: 33MHz
       Fähigkeiten: vga_controller bus_master cap_list rom
       Konfiguration: driver=i915 latency=0

according to Release Note,  Intel HD driver and OpenCL SDK is included in this package, I read the different numbers of Release note about OpenCL SDK, it is very complicated to understand , which version of OS and SDK  should i used for OpenCL  implemention.

I tried to  run the Intel Media Server  sample code, it's compiled  but for execution it's required the   lib file :

/Media_server/mediasdk-tutorials-0.0.3/_build$ ./simple_session
libva info: VA-API version 0.35.0
libva info: va_getDriverName() returns 0
libva info: User requested driver 'iHD'
libva info: Trying to open /opt/intel/mediasdk/lib64/iHD_drv_video.so
libva info: Found init function __vaDriverInit_0_32
libva error: /opt/intel/mediasdk/lib64/iHD_drv_video.so init failed
libva info: va_openDriver() returns 1
terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc
Unrecognized device ID 0166Abgebrochen (Speicherabzug geschrieben)

Q1->  i have installed the right version for OpenCL implemention.

Q2-> How i execute the sample code of Media server and OpenCL .

Q2-> Intel provide any up-to-date  document for understand the OpenCL implementation  requirements.

" i am new on Intel software , may those are  basic Question".

Best Regards,

Zeshan.

I see you have 3rd generation system, which is not officially supported. By that I mean, any releases available publicly has not been tested on 3rd generation processor and any new feature has not been added for 3rd gen or any bug fixes will not happen on unsupported platform.This is a possible reason that you are seeing issue in running tutorial. In case, you want to give it a shot then I would recommend this -  

Simple way to check if Media Server Studio is installed properly is mentioned in the 4th question "How can I check if Media Server Studio is installed correctly for my OS?"  of FAQ. Please try to run pre-compiled binaries to verify installation. Also, please make sure you have booted into right kernel. From the tutorial o/p, it looks like to kernel issue. Please check the steps mentioned in getting started guide for the pre-requisites and installation. 

For OpenCL queries, please check the documentation or FAQ here, post your questions on OpenCL forum. 

Thanks,
