MFX/MSDK and OpenCL interop on Linux ?

Hi, I am planning to optimize one of my modules with OpenCL.

I am using CentOS 7.1 and MSDK 2015R6. I looked up the example/sample codes provided by Intel. Two examples that deal with MSDK and OpenCL interop are all for Windows, as they both depend on the function clEnqueueAcquireDX9MediaSurfacesKHR() to use media surfaces as OpenCL memory objects, and that function only works with the DX9 adapter API.

Two other examples (motion estimation) that do work on Linux appear to be just OpenCL. I don't see MSDK and OpenCL interop in them.

How to Change the Target type drop-down to Correctness Analysis


This is my first post to the forum.
I am testing advisor_xe_2016.1.0.423501 on a E5-2690 v3 cpu using the nqueens tutorial.
According to the html doc "Predict Parallel Data Sharing Problems", i should be able to:

Change Intel Advisor Project Properties:
In the Intel Advisor GUI, choose File > Project Properties....
In the Analysis Target tab:
Change the Target type drop-down to Correctness Analysis.

__builtin_isinf, __builtin_isnan, __builtin_isfinite not working on Mac OS X 10.10

On Mac OS X 10.10.5 using Intel compiler version 16.0.0 the functions __builtin_isnan, __builtin_isinf, and __bultin_isfinite are not implemented correctly.

Here is a minimal test-case against the Intel compiler:


Hotspot analysis not launching application

Hi there

I am running Visual Studio 2013 on Windows 10, and Intel VTune Amplifier XE 2015.

I built my application in release mode (full optimization and debug symbols), I even enabled the Microsoft Debug Symbols server, but when I try to perform a basic hotspot analysis (or any analysis for the matter...) the exe is never launched, and eventually I get an error.

libiomp5.so (with ompt support) cannot trigger ompt_intialize() in an offload openmp environment

I'm running an Intel MIC offload openmp application using openmp runtime (with ompt support, both the CPU side and the MIC side), while libiomp5.so on the CPU side can trigger its ompt_intialize() and get profile data, libiomp5.so on the MIC side cannot trigger its ompt_intialize(), so that I cannot get the profile data I want. I'm wondering where the problem is.

Cause for remark #11074: Inlining inhibited by limit max-size

#11074: Inlining inhibited by limit max-size 
#11074: Inlining inhibited by limit max-total-size 
#11076: To get full report use -qopt-report=4 -qopt-report-phase ipo


I recently started getting these remarks when building a set of C++ files with the Intel compiler. I would like to know more about what it's trying to communicate, but haven't found much online. It's even omitted from the diag-dump list.


Does anyone have more information on it? I'd like to be able to 'fix' the root cause and remove it from my list of diag-disable warnings.


Saa3d please refrain from posting "likes" to old posts

While I do not wish to restrain you from meaningful comments on new threads, I do kindly ask that you do not post what amounts to a Facebook "like" to old threads. In doing so, this causes a great inconvenience to the contributors to the forum in the sense that we have to take some time to re-read old content in order to discover we did not need to re-read the thread. Scrolling to bottom of thread takes time. Too many of these "likes" conditions the valued responders to NOT read threads where your "like" is the last post.

The newest compiler still fail in compiling stringstream

int main()
	std::stringstream ss("");
	double doub;
	ss << 3213.0;
	ss >> doub;      // comment it then compile successfully
	return 0;

In Debug mode, it compiles successfully, but fails in Release mode.

I don't know how to solve this problem. if you know please show me, thank you.

installing Intel Paralle Studio XE Composer Edition for Fortran and C++ Windows

Dell model:T7610 I have 64bit windows 7 We've been trying to install Intel Paralle Studio XE Composer Edition for Fortran and C++ Windows. The trouble we're having is that it will not complete the install. After the certificate install. The Intel splash screen will come up and look like it was about install but then the splash screen disappears.
