Alignment problem

Dear Intel Developers,

I'm using Intel icc 15.0.1 version on a C program. I'm trying to align a structure of arrays and the same structure is passed to a computational kernel that uses Intrinsics. I'm not sure I'm doing the right allocations:

 

Get the Power Consumption Info When Running a Program

Hi,

When I run a program using offload mode, I want to collect the information of power consumption of the MIC. Is there any way to do that?

I found that I can use the micsmc to get the Total Power info in the command line/GUI interface.(https://software.intel.com/en-us/blogs/2014/01/31/intel-xeon-phi-coproce...) Could I add a function from any libraries inside a program to collect the power consumption when use offload mode?

Installing VTune on a VM

I am trying to get VTune installed in a virtual environ. Specifically, an Amazon EC2 instance running ubuntu. I understand not all hardware counters are exposed, so functionality may be limited (Per Thomas Wilham's response). But all I need to get is a system wide hotspot (which process->function takes most time). I tried to install the drivers and have the following error throw up.

 

 

sudo ./insmod-sep3 -r -g users

ERROR: XEN dom0 is not supported ... exiting.

grep: /proc/xen/capabilities: No such file or directory

Hot spot analysis of MPI applications

Hi There,

I am using Intel's VTune Amplifier XE 2016 integrated in Visual Studio 2015 to do hotspot analysis. Can anybody tell me how to analyse an MPI application?

What I did is as follows.

In the "Application"  field of the Amplifier Project Properties, add "C:\Program Files (x86)\IntelSWTools\mpi\5.1.2.146\intel64\bin\mpiexec.exe"

in the "Application parameters" field of the Amplifier Project Properties, add "-n 4 C:\Users\wang.j\VS2015\C30\C30\x64\Release\C30.exe"

Remote procedure call, license of code call to scif library

Hi,
We have developed a low latency, remote procedure call (rpc) Framework  for Xeon <--> Xeon Phi based on SCIF, which is very successful for our applications.  We think it could be helpful for other Intel Xeon Phi  users.  We would like to share the code to communities as open-source project. However we does not know if  there are any problem with Intel's license, copyright or copyright infringement, which we believe do not. Would you please help us? Thanks, Minh

Where is HEVC hardware accelerated plugin located.

Hello,

I have installed the new Intel(R)_Media_SDK_2016.0.1 and only the following files are present (in bin win32/x64):

I also have installed Intel(R) Media Server Studio 2015 R6 and it has ONLY x64 lib's and dll's:

My questions are:

Error: [Instrumentation Engine]: Failed to allocate Injector

Hi,

I am new to this forum and Intel software.

I encountered some problems with Intel Advisor XE (2016 update 2) while I am using it for my program written in Fortran. I use with Microsoft Visual Studio 2013. Since 2 months ago, I have no problem in analyzing with Advisor XE until yesterday. My machine is x64 and I compiled in 64bit as well. Windows 7 professional 64 bit.

The error shows once I start 'Survey Target'. The error message is as below:

kernel version 3.16.x support ?

Hello,

In getting started guide it shows that it is possible to use kernel 3.14.5 (with Intel's patches).

The thing is that we use video4linux capabilities and we need a more update kernel.

We need to use at least version 3.16.X

Is it possible to patch this kernel with intel's patches and use it with media sdk server ?

Thank you for the time,

Ran

SGX - Self-modifying Code

Is self-modifying code allowed in SGX enclaves?  I created a simple example that just calls a function stored in a data buffer.  I changed the properties for the enclave DLL so that data is also executable.  It worked when I compiled the project in simulation mode, but it crashes in hardware mode.
