MFXVideoENCODE_Query() always returns MFX_ERR_UNSUPPORTED


I need a help with MFXVideoENCODE_Query() from Intel Media SDK. I wrote code posted below and unfortunately it doesn't work. MFXVideoENCODE_Query() always returns error MFX_ERR_UNSUPPORTED. I played with parameters, but each time failed.

At the same time, I'm able to encode video with these parameters using HW HEVC encoder on my Skylake. So, only MFXVideoENCODE_Query() doesn't work correctly for me.

I tried do the same for AVC codec and also tried to call MFXVideoENCODE_Query() after MFXVideoUSER_Load(), but in both cases I constantly get the same error.

Compiling LTTng for the Xeon Phi


I am currently in trying to compile LTTng for the Xeon Phi for the first time, I started by trying to compile Userspace-RCU which should support the Xeon Phi, as x86_64-linux-k1om is recognized. I am using GCC provided in the MPSS release, as I do not need vectorisation for it. I am using a CentOs 6.6 computer with mpss 3.4.2 installed on it. Intel Parallel studio 2015 is also installed.

I am currently trying :

CC=/opt/mpss/3.4.2/sysroots/x86_64-mpsssdk-linux/usr/bin/k1om-mpss-linux/k1om-mpss-linux-gcc ./configure --host=x86_64-k1om-linux


Memory issues in concurrent_hash_map

Dear all,

I have noticed some memory issues which were similar to what has been reported in 597165. However our context is running plugins code in host applications, which manifests the leak as the fact that unless we kill the host application, a big chunk of memory ( allocated and supposedly released by the plugin code ) was never returned to system.

Media SDK in GVT-D or GVT-G


I would like to try to use the Intel Media SDK in a GVT-D or GVT-G configuration under Xen or KVM (Esxi seems not good at any of the two technology).

The problem is: which Chipset and CPU supports GVT-*

Intel is not clear regarding the support. Reading around it seems you need a Xeon with Iris PRO. Iris and HD are not enough. Nor a Core i7 with Iris Pro.

Is there a particular place where you can check for it?

Advisor 2015 XE not working with Visual Studio 2015

I had installed Parallel Studio XE 2015 Update 5 on a Windows 10 Pro x64 machine.  Integration into Microsoft Visual Studio 2013 worked with Inspector, Amplifier, and Advisor showing up in the VS menu bar.  Integration into Microsoft Visual Studio 2015 worked only for Amplifier. How to fix Intel Inspector 2015 XE and Advisor 2015 XE with Visual Studio 2015 please help.
Thank you.

Using OpenCV with ICC and MIC


I am working on my master thesis that involves using Intel Xeon Phi for image processing. I intend to use OpenCV libraries for the image processing, matrix multiplication and similar needs.

Firstly I have set up OpenCV for classic GCC compiler, and tested some basic code in Eclipse, that worked fine.
